TECHNICAL FIELD
[0001] Embodiments of the invention relate to control devices for at least one power system component and devices, systems and methods associated with such control devices. Embodiments of the invention particularly relate to control devices for at least one power system component having different control modes, mobile devices configured to interact with such control devices, and methods of controlling the operation of such control devices. BACKGROUND
[0002] Power systems are important infrastructure components. Power systems, such as power generation systems, power transmission systems and / or power distribution systems, comprise power system components. Switchgear, such as switches or circuit breakers, are a typical representative of power system components in primary systems.
[0003] Modern systems employ control devices to operate power system components. Intelligent electronic devices (IEDs) are one embodiment of such control devices.
[0004] Control devices can have different control modes. Providing such different control modes is useful to safeguard engineers that can have to be dispatched to the location of the control device to perform work, such as maintenance work. The different control modes can prevent the control device from being remotely controlled when an engineer of the control device sets the control device in a local control mode.
[0005] Changing the control mode can be achieved through mechanisms that require physical interaction of an engineer with the control device. Using a physical key that can be engaged with the control device or entering a code by pressing user interface elements of the control device are examples of such techniques that require physical interaction of an engineer with the control device.
[0006] There are several drawbacks to mechanisms that require physical interaction of an engineer with the control device to change its control mode. In case of a malfunction of the control device or of the power system substation in which the control device is arranged, the requirement of physical interaction can put the engineer at risk. The requirement of physical interaction also makes it more cumbersome to restore the control device to a remote control mode in case the engineer inadvertently left it in a local control mode when leaving the site where the control device is located. SUMMARY
[0007] It is an object of the present invention to provide an apparatus, a system and a method that address one or more of the above disadvantages. It is a further optional object of the present invention to provide a control device and a mobile device configured to interact with the control device that provides enhanced safety for engineers. It is a further optional object of the present invention to provide a control device and a mobile device configured to interact with the control device that facilitates setting the control device into a remote control mode even if the engineer is no longer on site.

[0172] Embodiments of the invention will be described with reference to the accompanying drawings. In the drawings, like or similar elements are referred to with like or similar reference numerals.
[0173] Although embodiments will be described in connection with a control device configured to control a switching device, embodiments are not limited thereto.
[0174] Features of embodiments can be combined with each other unless specifically stated otherwise.
[0175] Figure 1 A control device 20 for at least one power system component is shown. The control device 20 comprises at least one control circuit 30. The at least one control circuit 30 is configured to be coupled to a communication interface 21. The at least one control circuit 30 is configured to be coupled to the at least one power system component.
[0176] The control device 20 has different control modes. The different control modes can comprise a local control mode and a remote control mode.
[0177] The at least one control circuit 30 is configured to perform a transition between the different control modes of the control device 20. The at least one control circuit 30 is configured to receive data from the communication interface 21 and to set the control device 20 in the local control mode based on the received data if a user of a mobile device is located in a first location local to the control device 20.
[0178] The at least one control circuit 30 is further configured to set the control device in the remote control mode in response to a request of the user of the mobile device from a second location remote with respect to the control device 20.
[0179] The at least one control circuit 30 can also be configured to set the control device 20 to the remote control mode in response to a request by a user of the mobile device from a first location local to the control device 20. Thus, the at least one control circuit 30 can be configured to set the control device 20 to the remote control mode in response to a request from a user of the mobile device, which can be generated at a first location local to the control device or at a second location remote to the control device.
[0180] The at least one control circuit 30 can include any one or any combination of an integrated circuit, an integrated semiconductor circuit, a processor, a controller, an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), a circuit(s) including a qubit and / or a quantum gate, but is not limited thereto.
[0181] The at least one control circuit 30 can include a control mode transition circuit 31 configured to control a transition between control modes of the control device 20. The change in control mode can be performed based on determining that a user of the mobile device interacting with the control device 20 is authenticated to trigger the change in control mode. In the case where a request to set the control device 20 to the remote control mode is received from the second location remote to the control device 20, the at least one control circuit 30 can perform additional authentication operations. These additional authentication operations can be performed to ensure that the user setting the control device 20 to the local control mode from the first location local to the control device 20 also sets the control device 20 to the remote control mode from the second location remote to the control device 20.
[0182] Depending on the control mode of the control device 20, the control device 20 can be configured to perform different actions to operate the at least one power system component. To illustrate, and as will be explained in greater detail below, depending on whether the control device 20 is in the local control mode or the remote control mode, the control device 20 can be configured to react differently to an incoming signal, data, command, or request.
[0183] Figure 2 The control device 20 is shown. Reference is made to Figure 1 Features and components described are denoted by the same reference numerals as Figure 1 in the above detailed description.
[0184] The control device 20 also includes a power system component interface 22 configured to communicatively couple to the at least one power system component.
[0185] The control device 20 can further be configured to generate and output an operation signal or operation command to operate at least one power system component. The operation signal or operation command can cause a switching device of the at least one power system component to trip. To illustrate, the control device 20 can cause a circuit breaker (CB), switch or other switching device to trip.
[0186] The at least one control circuit 30 can comprise an operation signal generation circuit 35 configured to generate an operation signal or operation command for output via the power system component interface 22.
[0187] The at least one control circuit 30 can be configured such that, in case the control device 20 is in the local control mode, the operation signal generation circuit 35 operates the at least one power system component in response to a signal or command from a first location in the vicinity of the control device 20. The first location can comprise or be a substation in which the control device 20 is installed.
[0188] The at least one control circuit 30 can be configured such that, when the control device 20 is in the remote control mode, the operation signal generation circuit 35 operates the at least one power system component in response to a signal or command from a second location that is remote with respect to the control device. The second location can be arranged outside the substation in which the control device 20 is installed. To illustrate, the second location can be at a control center, or another location in which a monitoring system of the power system allows a user to interface with the monitoring system.
[0189] Figure 3 The control device 20 is shown. Reference is made to Figure 1 and Figure 2 Features and components described are denoted with the same reference signs as in Figure 1 and Figure 2 .
[0190] The control device 20 can further comprise an authentication circuit 32. The authentication circuit 32 can be configured to determine, based on data received at the at least one communication interface 21, whether data or a request received at the at least one communication interface 21 originates from a user that is authorized to trigger a control mode change.
[0191] The authentication circuit 32 can be configured to process data received at the at least one communication interface 21 from the mobile device to retrieve authentication keys or other authentication data therefrom. The authentication circuit 32 can be configured to compare the received authentication data with authentication data stored in a non-volatile manner in the storage means 24 of the control device 20. If the authentication circuit 32 determines that the user of the mobile device is authorized to set the control device 20 in the local control mode, the control device 20 can be configured so that the at least one control circuit 30 sets the control device 20 in the local control mode based on said data. The authentication circuit 32 can also be configured to process a request that can be received from the monitoring system to determine whether said request originates from the user of the mobile device, whether it is to result in the control device 20 being set in the local control mode.
[0192] The authentication circuit 32 can be configured to store the authentication data in the non-volatile control device storage means 24 for later use when the identity of the user needs to be determined. To illustrate, the authentication circuit 32 can store the authentication data received from the mobile device in the storage means 24. In the case where the user is located in a second location remote from the control device 20, the authentication circuit 32 can retrieve the stored authentication data when processing a received request.
[0193] The control device 20 can also be configured so that it limits the possibility of setting the control device 20 in the remote control mode from a second location remote with respect to the control device 20. The control device 20 can use various criteria such as, but not limited to, time-based criteria for limiting the possibility of setting the control device 20 in the remote control mode from the second location. The control device 20 can comprise a time condition verification circuit 33 configured to check whether a request is received within a given time interval following the setting of the control device 20 in the local control mode. The time condition verification circuit 33 can comprise a timer that is started in the case where the control device 20 is set in the local control mode based on received data. When a request is received, the time condition verification circuit 33 can be configured to compare the time elapsed since the control device was set in the local control mode with the given time interval. If the request is received within the given time interval, the control circuit 30 is configured to set the control device 20 in the remote control mode based on said request.
[0194] The control device 20 can be configured so that the duration of the given time interval is adjustable. The duration of the given time interval can be set when the control device 20 is configured or commissioned. The duration of the given time interval can be adjusted by an operator of the power system during the field use of the control device 20.
[0195] Figure 4 The control device 20 is shown. Reference is made to Figures 1 to 3The described features and components are designated with the same reference numerals in Figures 1 to 3 the middle.
[0196] The control device 20 can further comprise a code generation circuit 34. The code generation circuit 34 can be configured to generate and output a code comprising at least one parameter of a communication channel for receiving data from the mobile device. The code can comprise both the parameter of the communication channel via which the data is received and a unique control device identifier. The code can comprise a wireless security key and an identifier of the control device 20. The code can be configured to enable the mobile device and the control device to establish a communication channel via which the control device 20 receives data. The control device 20 can be configured such that the code defines the parameter of the communication channel via which the communication channel is a temporary point-to-point wireless connection between the mobile device and the control device 20. Thereby, the control device 20 can provide the mobile device with the information required to generate the data and request.
[0197] The code can comprise a visual code. The control device 20 can further comprise an optical output interface 25 configured to output the code. Thereby, the control device 20 can provide the mobile device with the information required to generate the data and / or request while ensuring that the mobile device has to be located in a first location (e.g. within visual distance of the control device 20). The optical output interface 25 can be a control device display arranged within a housing of the control device 20 to expose a display area for reading the code.
[0198] The code generation circuit 34 and the optical output interface 25 can be configured such that the code comprises a graphical code. The graphical code can comprise a two- dimensional graphical code and / or a barcode. The graphical code can comprise a two- dimensional barcode.
[0199] The at least one communication interface of the control device 20 can comprise more than one communication interface. For illustration, the control device 20 can have a first communication interface 21 and a second communication interface 24. The first communication interface 21 can be configured to receive data from the mobile device via a wireless communication channel. The wireless communication channel can be a communication channel of a wireless point-to-point connection. The control device 20 can be configured to send an acknowledgement data to the mobile device via the first communication interface 24 in case the mobile device is located in a first location locally to the control device 20.
[0200] The second communication interface 24 can, but need not, be configured to receive data directly from the mobile device. The second communication interface 24 can be configured to interface the control device 20 communicatively with a monitoring system such as a supervisory control and data acquisition (SCADA) system and / or a fleet management (FLM) system. The second communication interface 24 can be a wired interface.
[0201] The control device 20 can be configured to receive data from the mobile device via the first communication interface 21. If the request is generated remotely from the control device 20, the control device 20 can be configured to receive the request to set the control device 20 to the remote control mode via the second communication interface 24. If the request is generated locally from the control device 20, the control device 20 can also be configured to receive the request to set the control device 20 to the remote control mode via the first communication interface 21.
[0202] Figure 5 is a flowchart of a method 40 of operating a control device for at least one power system component. The method 40 can be performed automatically by the control device 20.
[0203] In process block 41, at least one control circuit of the control device receives data from a communication interface. The data can be received at the communication interface via a wireless communication channel, such as a wireless point-to-point connection.
[0204] In process block 42, the at least one control circuit sets the control device to a local control mode based on the received data. Setting the control device to the local control mode can include authenticating a user of the mobile device based on the received data. Information about the identity of the user, such as authentication data or a unique user identifier for the user, can be stored in the control device for later use.
[0205] In process block 43, the control device receives a request to set the control device to a remote control mode. The request can, but need not, be received via the wireless interface. The request can come from a SCADA or FLM system.
[0206] In process block 44, the at least one control circuit sets the control device to the remote control mode based on the received request. Setting the control device to the remote control mode can include verifying that the request originated from the user of the mobile device that caused the data received in process block 41 to be sent to the control device.
[0207] While the request in process block 43 can originate from a second location that is remote with respect to the control device, the control device can be configured to also set the control device to the remote control mode using a request that originates from a first location that is local to the control device, e.g., within a substation in which the control device is installed.
[0208] Figure 6 is a flowchart of a method 50 of operating a control device for at least one power system component. The method 50 can be performed automatically by the control device 20. The method 50 can be performed to set the control device to a local control mode. The method 50 can be performed to implement process block 42 of the method 40.
[0209] In process block 51, the control device generates and outputs a code. The code can include both parameters of a communication channel via which data is received and a unique control device identifier. The code can include a wireless security key and a control device identifier. The code can be configured to enable the mobile device and the control device to establish a communication channel via which the control device receives data. The control device can be configured such that the code defines parameters for a communication channel that is a temporary point-to-point wireless connection between the mobile device and the control device. Thereby, the control device can provide the mobile device with information needed to generate data and make requests.
[0210] The code can include a visual code. Outputting the code can include outputting the visual code via a display of the control device. The visual code can include a graphical code. The graphical code can include a two-dimensional graphical code and / or a barcode. The graphical code can include a two-dimensional barcode.
[0211] In process block 52, the control device obtains information about the identity of a user of the mobile device located at a first location local to the control device. Obtaining information about the identity of the user can include retrieving authentication data based on data received at an interface of the control device. The data received at the interface can be data transmitted by the mobile device in accordance with communication parameters specified in the code generated and output in process block 51.
[0212] In process block 53, it is determined whether the user is authenticated to change the control mode of the control device. Determining whether the user is authenticated to change the control mode can include determining, based on the received data, whether authentication data included in the received data matches authentication data initiated locally to the control device.
[0213] In process block 54, if the user is authenticated to change the control mode, the information about the identity of the user is stored in the control device for subsequent use. The control mode is set to the local control mode.
[0214] In process block 55, if it is determined that the user is not authorized to change the control mode, the control mode can be maintained as the remote control mode.
[0215] Thereby, the control device can provide the mobile device with information needed to generate data and / or make requests while ensuring that the mobile device must be within a visual distance.
[0216] The control device can be configured to store information included in the code in non-volatile control device storage in association with a user identifier and / or remotely in a monitoring system. The stored information can include authentication keys included in the data and the code generated by the control device to enable the control device and the mobile device to establish a communication channel.
[0217] Therefore, the control device can ensure that requests to set the control device to remote control mode originate from mobile device users who are using mobile devices when the control device is set to local control mode.
[0218] Figure 7 This is a flowchart of a method 60 for operating a control device for at least one component of a power system. Method 60 can be executed automatically by the control device 20. Method 60 can be executed to set the control device to a remote control mode. Method 60 may include performing another user authentication before setting the control device to the remote control mode. Method 60 can be executed to implement process block 44 of method 40.
[0219] In process block 61, the control device determines the user's identity based on a received request. The request may be a request to set the control device to remote control mode. The request may be received from a second location remotely relative to the control device. The request may be received from a monitoring system device remotely located (e.g., located outside the substation where the control device is located). Authentication data may be retrieved from the request. Authentication data may be uniquely assigned to a user.
[0220] In process block 62, the control device determines whether the determined user identity matches a previously stored user identity. The previously stored user identity may include data uniquely identifying the mobile device user who triggered the setting of the control device to local control mode. The previously stored user identity may be stored locally on the control device or in a location remote from the control device, such as in a monitoring system.
[0221] In process block 63, if the determined user identity matches the stored user identity, the control device may optionally determine whether a time-based criterion is met. The time-based criterion may include a timeout criterion. The time-based criterion may include checking whether the time elapsed since the control device switched to local control mode (e.g., since receiving data from a communication interface or since at least one control circuit set the control device to local control mode) is less than a threshold value at the time the request was received. This threshold value may be settable. The time-based criterion reduces the risk of unintentionally changing the control mode.
[0222] In process block 64, if the determined user identity matches the stored user identity and if the time-based criteria are met, the control device is set to remote control mode.
[0223] In process block 65, if the determined user identity does not match the stored user identity or if the time-based criteria are not met, the local control mode of the control device is maintained. In this case, the user of the mobile device can set the control device to remote control mode by going to the first location on the control device.
[0224] according to Figures 1 to 4 Any one of them can be executed Figures 5 to 7 The control device 20 of any of the methods can be an intelligent electronic device (IED). The control device 20 can be configured to interface with a data acquisition unit, such as a merging unit (MU), to operate at least one power system component. The control device 20 can be configured to interface with a monitoring system, such as a SCADA or FLM system. The control device 20 can be configured to operate switching devices, such as CBs or switches. The control device 20 can be installed in a substation of a power system, such as a substation of a high-voltage or medium-voltage power system or a DER system. The control device 20 can be an IED configured to operate in a manner compatible with IEC 61850.
[0225] Control device 20 is configured to interface with mobile devices in a communicative manner. (Refer to...) Figures 8 to 12 A more detailed explanation of the configuration and operation of mobile devices.
[0226] Figure 8 A mobile device 70 is shown. The mobile device 70 is configured to interact with a control device (such as a reference device) for at least one power system component. Figures 1 to 4 Interact with any of the control devices described in the text 20).
[0227] The mobile device 70 includes a mobile device communication interface 71. The mobile device 70 includes at least one mobile device circuit 72.
[0228] The mobile device circuit 72 is configured to send data to the control device via the mobile device communication interface 71 if the user of the mobile device 70 is located at a first location local to the control device, so as to set the control device to local control mode.
[0229] The mobile device circuit 72 is configured to enable a user of the mobile device 70 to set the control device to a remote control mode from a second position relative to the control device.
[0230] Therefore, the mobile device 70 is configured to allow the control device to be set to a local control mode, while reducing the need for direct physical contact between the user and the control device in the first location. The mobile device 70 can act as an interface device configured to connect the user to the control device.
[0231] Mobile device 70 is configured to allow the control device to be set to remote control mode without the user of the mobile device being present at a first location local to the control device. Mobile device 70 may be configured as a token providing the data or other information required to set the control device to remote control mode from a second location. For illustration, mobile device 70 is configured to enable the control device to be set to remote control mode from a monitoring system device installed outside the substation where the control device is installed or at another location remote from the control device.
[0232] The mobile device 70 can also be configured to generate and send a request to set the control device to local control mode when the mobile device 70 is located in a first position local to the control device.
[0233] Mobile device 70 may include mode control circuitry 73 configured to generate data that sets the local device to a remote control mode. Mobile device 70 may be configured to transmit the generated data via at least one mobile device communication interface 71. Mobile device 70 may be configured to control a mobile device wireless interface of at least one mobile device communication interface 71 to transmit data via a wireless peer-to-peer connection.
[0234] The mode control circuit 73 can be configured to generate and provide information that enables the control device to be set to a remote control mode. This information may, but does not need to, be output via at least one mobile device communication interface 71. Information that enables the generation of a request to set the control device to remote control mode can be output via the mobile device's interface under the control of the mobile device control circuit 72 via an interface different from at least one mobile device communication interface 71 (such as a graphical user interface (GUI)).
[0235] The mobile device 70 can be configured to perform biometric authentication on the user before generating and sending data that sets the control device to remote control mode and / or before providing information that enables the control device to be set to remote control mode.
[0236] Figure 9 A mobile device 70 is shown. (Reference) Figure 8 The described features and components adopt the same Figure 8 The same reference numerals are used in the accompanying drawings.
[0237] Mobile device 70 includes a biometric authentication circuit 74 configured to perform biometric authentication for a user. The biometric authentication circuit 74 may be coupled to a biometric sensor 77. The biometric sensor 77 may include a photoelectric sensor, such as the camera sensor of mobile device 70. The biometric sensor 77 may be configured to capture an image of the user of mobile device 70. The biometric authentication circuit 74 may perform biometric authentication based on facial recognition processing and / or iris feature recognition processing of the captured image. Other biometric authentication components, such as a fingerprint sensor, may be used.
[0238] Mobile device 70 can be configured to selectively send data to a control device based on successful biometric authentication of a user. Mobile device 70 can be configured such that the data content of the sent data (such as authentication data included in the sent data) depends on the output of biometric authentication circuit 74.
[0239] Mobile device 70 can be configured to selectively provide information that enables the control device to be set to local control mode based on another successful biometric authentication of the user. Mobile device 70 can be configured such that at least a number of pieces of information (such as the device identifier of the control device and / or the user identifier of the user) depend on the output of biometric authentication circuit 74.
[0240] For illustration, mobile device 70 can be configured to identify the user of mobile device 70 based on another biometric authentication. Mobile device 70 can be configured to retrieve a unique identifier of a control device previously set to local control mode by the identified user. Mobile device 70 can provide information depending on both the retrieved unique identifier of the control device and the identified user, enabling the control device to be set to remote control mode.
[0241] At least one mobile device circuit 72 can be configured to generate data based on biometric authentication and send the data to a control device. At least one mobile device circuit 72 can be configured to provide user authentication data based on biometric authentication of a user by the mobile device 70. The authentication data may include an authentication key required by the control device to authenticate the user of the mobile device 70. The mobile device may include a non-volatile storage device. At least one mobile device circuit 72 can be configured to identify and retrieve authentication data stored in the non-volatile storage device based on biometric authentication, in order to provide the authentication data to the control device.
[0242] Figure 10 A mobile device 70 is shown. (Reference) Figure 8 and Figure 9 The described features and components adopt the same Figure 8 and Figure 9 The same reference numerals are used in the accompanying drawings.
[0243] Mobile device 70 also includes a code capture sensor 78. Code capture sensor 78 may include another photoelectric sensor, such as another camera sensor. Biometric sensor 77 and code capture sensor 78 may be integrated into the same camera chip or may be separate camera sensors. For illustration, code capture sensor 78 may include a first camera sensor of mobile device 70 facing a first viewing direction (such as a front-facing camera sensor). Biometric sensor 77 may include a second camera sensor of mobile device 70 facing a second viewing direction different from the first viewing direction (such as a user-facing camera sensor).
[0244] The code capture sensor 78 can be configured to capture codes output by the control device. At least one mobile device circuit 72 may also include a graphic code processing circuit 75 configured to transmit data to the control device based on the captured code. The code may include parameters of a communication channel through which data is transmitted. The parameters of the communication channel may include parameters of a wireless peer-to-peer communication channel through which data is transmitted. The parameters may include a wireless security key. The code can be configured to enable the mobile device 70 to establish a communication channel with the control device to transmit data to the control device. The communication channel may be a temporary peer-to-peer wireless connection between the mobile device 70 and the control device.
[0245] The code may include visual code that can be captured by code-capturing sensor 78, which includes another photoelectric sensor. The code may also be embodied in other ways, such as signals transmitted via wired or wireless means.
[0246] The code may include a graphic code. The graphic code may include a two-dimensional graphic code and / or a barcode. The graphic code may include a two-dimensional barcode. The graphic code processing circuitry 75 may be configured to process the graphic code to determine parameters of a communication channel through which data is transmitted.
[0247] The code may also include a unique identifier for the control device. Graphical code processing circuitry 75 may be configured to process the graphical code to determine the unique identifier for the control device. The unique identifier for the control device may be stored in a non-volatile mobile device storage device 76 for maintaining a dataset that defines, in a user-specific manner, which control devices are set to local control mode using the mobile device 70.
[0248] Mobile device 70 can be configured to store information included in the code in association with a user's identifier (such as authentication data) in a non-volatile mobile device storage device 76. The stored information may include the user's authentication key (such as an authentication key stored back in mobile device 70 in response to confirmation from control device 20) and the code captured by the mobile device.
[0249] The mobile device may include a mobile device output interface. The mobile device output interface may include a GUI 79. The GUI can be configured to output information identifying the control device and the user. By providing information identifying the control device and the user, the mobile device 70 is configured to secure tokens that authenticate the user and the control device when the control device is set to remote control mode. The mobile device 70 can be configured in such a way that it enables the control device to be set to remote control mode from a second location remotely relative to the control device.
[0250] Mobile device 70 can be configured to maintain records in non-volatile mobile device storage device 76 indicating to each user which control device or control devices have been set to local control mode by the corresponding user of the mobile device. Information about the control device or control devices can be output via the mobile device's GUI 79.
[0251] Following biometric authentication, GUI 79 allows the user to select one of the control devices recorded as having been set to local control mode by the user. Mobile device 70 can be configured to generate and output information based on the selection, enabling the selected control device to be set to local control mode when the user is in a second location remotely relative to the control device. Mobile device 70 can also be configured to generate and send a request to the selected control device based on the selection, enabling the control device to be set to local control mode while the user is still in a first location local to the control device.
[0252] Figures 8 to 10 Any of the mobile devices 70 can be a portable device. Mobile device 70 can be a handheld device. Mobile device 70 can be a terminal of a cellular communication network.
[0253] Figure 11 This is a flowchart of method 80. Method 80 can be derived from... Figures 8 to 10 Execute on any of the mobile devices 70.
[0254] In process block 81, when the user of the mobile device is located at a first location local to the control device (e.g., at or within a substation where the control device is installed), the mobile device sends data to the control device for at least one power system component to set the control device to local control mode. The data may include the user's authentication data. Parameters of the communication channel captured by the mobile device from the control device can be used to send the data.
[0255] In process block 82, when the user of the mobile device is located in a second location that is remote relative to the control device (e.g., at a monitoring system device in a substation where the control device is installed), the mobile device provides information that enables the control device to be set to remote control mode.
[0256] The information may be provided via a mobile device's display or other optical output device.
[0257] The information provided in process block 82 can depend on both the user of the control device and the mobile device to be set to remote control mode. This enables a check to be performed to ensure that the control device is set to remote control mode from a remote location by the same user who set the control device to local control mode in the first location.
[0258] Figure 12 This is a flowchart of method 90. Method 90 can be derived from... Figures 8 to 10 Execute on any of the mobile devices 70.
[0259] In process frame 91, the mobile device performs biometric authentication on the user of the mobile device. Biometric authentication may include facial recognition, fingerprint recognition, and / or iris recognition. Subsequent process frames are executed based on successful biometric authentication, indicating that the user of the mobile device has been authenticated by the mobile device, to initiate a change in the control mode of the control device for at least one power system component.
[0260] In process block 92, the mobile device captures a code from the control device. The code may be a visual code captured using the mobile device's photoelectric sensors. The code may include graphic codes, barcodes, and / or two-dimensional barcodes. The code may include parameters of a communication channel through which the mobile device can send data to and optionally receive data from the control device. Process block 92 is executed when the user is located at a first location local to the control device (e.g., at or within a substation where the control device is installed).
[0261] In process block 93, with the user of the mobile device located at a first position local to the control device, the mobile device sends data to the control device to set the control device to local control mode. The data may include the user's authentication data. The data can be sent using parameters of the communication channel captured by the mobile device from the control device in process block 92.
[0262] In process block 94, the mobile device stores the control device identifier. The mobile device may store the control device identifier in association with the identifier of the user authenticated in process block 91. The mobile device may also store the control device identifier locally on the mobile device.
[0263] In process frame 95, the mobile device performs another biometric authentication for its user. This other biometric authentication may include another facial recognition, another fingerprint recognition, and / or another iris recognition. Subsequent process frames are executed based on the other biometric authentication indicating that the mobile device user has been authenticated by the mobile device in order to initiate a change in the control mode of the control device.
[0264] In process block 96, the mobile device retrieves the control device identifier. The mobile device may retrieve the control device identifier based on the user identity determined in another biometric authentication in process block 95.
[0265] In process block 97, when the user of the mobile device is located in a second location that is remote relative to the control device (e.g., at a monitoring system device in a substation where the control device is installed), the mobile device provides information that enables the control device to be set to remote control mode.
[0266] In process block 97, information can be provided via a display of a mobile device or other optical output device for acquisition by acquisition devices of a monitoring system (such as SCADA or FLM system).
[0267] The information provided in process block 97 can depend on both the user of the control device and the mobile device to be set to remote control mode. This enables the execution of checks to ensure that the control device is set to remote control mode from a remote location by the same user who set it to local control mode in the first location.
[0268] Figure 13 This is a diagram of a system including control device 20 and mobile device 70. Control device 20 may have a combination of... Figures 1 to 7 Any publicly disclosed configuration and functionality. The mobile device 70 can have a combination of... Figures 8 to 12 Any publicly available configurations and features.
[0269] In step 101, control device 20 generates and outputs code. This code can be output via a control device display or other optical output device of control device 20. The code may include communication parameters of a communication channel through which control device 20 can receive data from mobile device 70.
[0270] In step 102, mobile device 70 performs biometric authentication on the user of the mobile device and captures a code. Biometric authentication may include facial recognition, fingerprint recognition, and / or iris recognition. Mobile device 70 generates data based on the result of biometric authentication to be sent to control device 20. For illustration, the generated data may include authentication keys or other authentication data, which are stored in the mobile device of the user identified by biometric authentication. The data may also depend on communication parameters in the captured code, for example, when the communication parameters include a security key to be used to generate the data.
[0271] In step 103, mobile device 70 sends data 103 to set the control device to local control mode. Modulating data 103 into a signal may also depend on communication parameters included in the code output by control device 20 in step 101. This data may include the user's authentication key or other authentication data to authenticate the user of the mobile device via control device 20.
[0272] In step 104, the control device performs user authentication. The authentication in step 104 differs from the biometric authentication in step 102. The authentication in step 104 can be performed based on data 103. The authentication in step 104 can be performed based on the mobile device user's authentication key or other authentication data included in data 103.
[0273] In 105, the control device stores user information for the mobile device user. The user information can be any unique identifier for the user, such as the authentication key or other authentication data included in data 103. The control device can store the user information locally on the control device or in a monitoring system.
[0274] At step 106, the control device outputs confirmation data. This confirmation data can indicate that the user has been authenticated not only by the mobile device 70 but also by the control device 20. The confirmation data may include the user's unique identifier, which can then be stored back in the mobile device 70.
[0275] In step 107, the control device is set to local control mode. The control device 20 can respond to data 103 or further transmissions from the mobile device 70 if the user has been authenticated by the control device. Figure 13 (Not shown in the image) is set to local control mode.
[0276] In step 108, the mobile device can store a unique control device identifier that controls the device. This unique control device identifier can be included in the code captured in step 102. The unique control device identifier can be stored in association with the user identified in the biometric authentication process in step 102.
[0277] In step 109, the mobile device provides information that enables the control device to be set to remote control mode. The provision of this information may depend on whether the mobile device is used by the same user as in process block 102. Mobile device 70 may perform further biometric authentication to determine the identity of the mobile device user. The provision of information may include output information (e.g., via the mobile device display) for acquisition and use by the monitoring system.
[0278] In step 110, the control device receives a request 110 to set the control device to remote control mode. Request 110 may, but does not need to, be generated by the mobile device 70. For illustration, the mobile device may output the information in step 109 via its display for the monitoring system to collect. The monitoring system device can then generate request 110. Request 110 may include the user's authentication key or other authentication data.
[0279] In step 111, control device 20 can perform another user authentication. Further user authentication can be performed based on the user's authentication key or other authentication data included in request 110. This additional user authentication may include checking, based on request 110, whether the user of the mobile device providing information in 109 has been authenticated by control device 20 to request a change in control mode. This additional user authentication may also include verifying, based on the user's authentication key or other authentication data included in request 110, whether the mobile device user providing information in 109 is the same user who caused control device 20 to be set to local control mode and whose identity is stored in 105.
[0280] In step 112, control device 20 may optionally check whether a time-based criterion is met. For illustration, request 110 may be selectively processed based on whether it was received within a given time period after data 103 was received or after local control mode operation was initiated in step 107.
[0281] In step 113, if the other user authentication in step 111 and the time-based standard in step 112 are both successful, then the control device 20 is set to remote control mode.
[0282] Figure 14 and Figure 15System 10 is shown. System 10 includes at least one power system component 11. At least one power system component 11 may include switching devices, such as CB, switches, or disconnectors. Switching devices may include, but are not limited to, switching devices for high-voltage or medium-voltage power systems or DER systems.
[0283] System 10 includes a control device 20 configured to operate at least one power system component 11 by issuing an operation signal or command 12. The control device 20 may have a combination of... Figures 1 to 7 or Figure 13 The configuration and functionality described in any of the above.
[0284] System 10 includes a mobile device 70 configured to interact with control device 20. The mobile device 70 can also be configured to interact with a monitoring system. The mobile device 70 may have a combination of... Figures 8 to 13 The configuration and functionality described in any of the above.
[0285] System 10 includes a monitoring system with monitoring system equipment 13. Acquisition device 14 (such as a camera) may be included in or coupled to the monitoring system equipment 13.
[0286] Control device 20 and mobile device 70 can be configured such that when user 15 of mobile device 70 is located at a first location 16 local to the control device (e.g., at a substation where control device 20 is installed or at a first location within a substation), user 15 can use mobile device 70 to set control device 20 to local control mode, such as... Figure 14 As shown. Setting the control device 20 to local control mode may involve an authentication process. The authentication process may include a multi-stage authentication process, including biometric authentication of user 15 at mobile device 70 and authentication of user 15 at control device 20 based on authentication data received by control device 20 from mobile device 70.
[0287] The control device 20 and the mobile device 70 can be configured such that when the user 15 of the mobile device 70 is located at a second location 17 remotely relative to the control device (e.g., at a monitoring system device 13 outside the substation where the control device 20 is installed), the user 15 can use the mobile device 70 to set the control device 20 to a remote control mode, such as... Figure 15As shown. Setting control device 20 to remote control mode may involve an authentication process. This authentication process may include a multi-stage authentication process, including further biometric authentication of user 15 at mobile device 70, and authentication of user 15 at control device 20 based on authentication data received by control device 20 from monitoring system device 13. Monitoring system device 13 may be configured to process information output by mobile device and collected by acquisition device 14. Monitoring system device 13 may be configured to determine the user's identity and a unique control device identifier based on the information output by mobile device and collected by acquisition device 14, in order to generate a request that causes control device 20 to be set to remote control mode.
[0288] Setting the control device 20 to remote control mode from the second position 17 can be selectively implemented based on whether a time-based criterion is met. For illustration, setting the control device 20 to remote control mode from the second position 17 can be selectively implemented for a period of time after the control device is set to local control mode. This time period can be fixed or configured, for example, during power system commissioning or configuration.
[0289] Control device 20 and mobile device 70 may optionally be configured such that when user 15 of mobile device 70 is located at a first location 16 local to control device 20 (e.g., at a substation where control device 20 is installed or at a first location within a substation), user 15 can use mobile device 70 to set control device 20 to remote control mode, such as... Figure 14 As shown. When user 15 is in the first position 16, the communication channel (such as a wireless point-to-point communication channel) established between mobile device 70 and control device 20 for setting control device 20 to local control mode can be re-established to use mobile device 70 to set control device 20 to remote control mode.
[0290] The monitoring system device 13 includes or is coupled to the acquisition device 14. The acquisition device 14 is configured to capture information output by the mobile device 70, wherein the output information includes a control device identifier and a user identifier. The monitoring system device 13 includes at least one monitoring system device circuitry configured to generate a request based on the acquired information to set the control device 20, identified by the control device identifier, to a remote control mode. The monitoring system device 13 may include a SCADA or FLM system device.
[0291] Acquisition device 14 may include a photoelectric sensor, such as a camera, configured to capture information from the mobile device display of mobile device 70. Monitoring system device 13 may be configured to receive reference information from control device 20, depending on a control device identifier and a user identifier. Monitoring system device 13 may be configured to generate a request based on a comparison of the reference information with the acquired information.
[0292] The monitoring system device 13 can be configured to determine the control device 20 based on the collected information. The monitoring system device 13 can be configured to provide a user identifier to the control device 20 based on the information.
[0293] If you have already referred to Figures 1 to 15 The disclosed devices, systems, and methods allow for setting control modes for control devices used in at least one power system component. The devices, systems, and methods reduce the need for physical contact between the user 15 and the control device 20. The devices, systems, and methods provide enhanced versatility in setting control modes for the control device 20.
[0294] To ensure safety requirements are met when user 15 is controlling the device 20 from location 17, the device, system, and method allow user 15 to be authenticated at the second location 17 to change the control mode of the control device 20 from the second location 17. The device, system, and method are configured to ensure that the user setting the IED to local control mode is the same user who can set the IED to remote control mode from the second location 17 or optionally from the first location 16. The device, system, and method are configured to provide an authentication scheme that ensures the person changing the control mode to local control mode can set the control mode to remote control mode.
[0295] User 15 can set control device 20 to local control mode by establishing a wireless connection from mobile device 70 to control device 20. On mobile device 70, biometric authentication may be required to grant user 15 access to the data needed to set the control mode of control device 20. Biometric authentication may include facial recognition, fingerprint recognition, and / or iris recognition, which are unique identifiers for the user.
[0296] The connection to control device 20 can be configured as a temporary wireless connection, which can be performed as follows: Control device 20 can generate and display a code (such as a barcode) containing encoded connection parameters, including an identifier of control device 20. Mobile device 70 can read the code. A peer-to-peer connection can be established between mobile device 70 and control device 20. The connection can be established based on whether the person identified on mobile device 70's authentication system matches the authentication on control device 20. This means that user authentication has been provided on control device 20. If successful, mobile device 70 again shares the authentication code with control device 20. After matching with control device 20, mobile device 70 can configure control device 20 to local control mode.
[0297] The authentication code and the identifier of control device 20 can be stored back on mobile device 70. This provides a general understanding of which control devices have been set to local control mode by user 15 and remain in local control mode. This information allows control device 20 to be securely set to remote control mode from second location 17. To verify whether the change in control mode from second location 17 was authorized by the same user 15, mobile device 70 can perform another biometric authentication.
[0298] To set control device 20 to remote control mode while user 15 is still in the first position 16, mobile device 70 is configured to allow user 15 to select control device 20 from one or more control devices stored in mobile device 70 that operate in local control mode. Mobile device 70 can re-establish point-to-point wireless communication. Based on another successful authentication of the user, control device 20 can be set to remote control mode.
[0299] To set control device 20 to remote control mode when user 15 is at second location 17, access to control device 20 can be implemented in a manner that ensures user 15 at second location 17 is the same user who previously set control device 20 to local control mode. Mobile device 70 can output another code (which could be another graphical code, such as another barcode). This other code can include a combination of the control device identifier and communication parameters previously captured by mobile device 70 from control device 20. This other code can be scanned by an FLM or SCADA system and grant permission to access control device 20 from second location 17. The status of control device 20 can be set back from local control mode to remote control mode via FLM or SCADA system. Upon success, a status overview can show control device 20 operating in remote control mode. The process of setting control device 20 to remote control mode can be time-limited to reduce the risk of unintentionally setting control device 20 to remote control mode during extended maintenance work.
