There is also the problem of high labor intensity and personal safety risks for operators because they need to frequently arrive at the site for manual operation.

[0036] The application scenarios of the relay protection remote control method and product for dispatching control system disclosed by the present invention are as follows: Figure 1 As shown, the remote control method for relay protection used in a dispatching control system disclosed in the present invention determines the set value zone number and whether the set value of the relay protection device are the same as the set value zone by remotely controlling the target zone where the relay protection device is located to be the set set value zone; remotely sets the throw-in / out state of the reclosing soft pressure plate of the relay protection device according to the target state, determines whether the throw-in / out state of the reclosing soft pressure plate and the charging and discharging state of the reclosing are the same as the target state; remotely modifies the set value of the relay protection device according to the target set value, determines whether the modified set value of the relay protection device is the same as the target set value; enables the operator to remotely operate the relay protection device and perform multiple protection checks, which can reduce the risk of human operation, improve the accuracy of operation, and improve work efficiency and accuracy.

[0037] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0038] In one embodiment of the present invention, Figures 1 to 5 As shown, a relay protection remote control method for a dispatching control system comprises:

[0039] like Figures 1 to 3 As shown, step S101, the target area where the remote control relay protection device is located is cut into the set fixed value area, and according to the execution result fed back by the relay protection device, the fixed value area number of the relay protection device and whether the fixed value is the same as the fixed value area are determined;

[0040] In this embodiment, the dispatching control system is arranged in the operation safety zone.

[0041] Exemplarily, the operation safety zone may be a pre-set safety zone.

[0042] like Figure 1 , Figure 2 and Figure 4 As shown, step S102, according to the target state, remotely set the throw-in / out state of the reclosing soft pressure plate of the relay protection device, and determine whether the throw-in / out state of the reclosing soft pressure plate and the charge-discharge state of the reclosing switch are the same as the target state according to the execution result fed back by the relay protection device;

[0043] Exemplarily, the dispatching and control system sends operating instructions to the relay protection device through a data communication gateway.

[0044] In this embodiment, the dispatching control system realizes the operation of the reclosing soft pressure plate through remote control or remote signaling services. For example, the state of the reclosing soft pressure plate changes from "on" to "off" or from "off" to "on"; correspondingly, the reclosing charge and discharge state changes from "charging" to "discharging" or from "discharging" to "charging".

[0045] like Figure 2 and Figure 5 As shown, in step S103, the setting of the relay protection device is remotely modified according to the target setting, and according to the execution result fed back by the relay protection device, it is determined whether the modified setting of the relay protection device is the same as the target setting.

[0046] This embodiment remotely controls the target area where the relay protection device is located to be the set fixed value area, determines whether the fixed value area number and the fixed value of the relay protection device are the same as the fixed value area; remotely sets the throw-in / out state of the reclosing soft pressure plate of the relay protection device according to the target state, determines whether the throw-in / out state of the reclosing soft pressure plate and the charging and discharging state of the reclosing are the same as the target state; remotely modifies the fixed value of the relay protection device according to the target fixed value, determines whether the modified fixed value of the relay protection device is the same as the target fixed value; enables the operator to remotely operate the relay protection device and perform multiple protection checks, which can reduce the risk of human operation and improve the accuracy of operation.

[0047] Based on the previous embodiment, another embodiment of the present invention further includes, before the target area where the remote control relay protection device is located is cut into a set fixed value area:

[0048] Get the actual set value of the relay protection device, and determine whether the actual set value is the same as the reference set value corresponding to the target area in the database. If they are the same, the target area is allowed to be cut into the set set value area.

[0049] In this embodiment, the relay protection device uses the dispatching data network as a data transmission channel between the dispatching control system and the relay protection device. Exemplarily, the dispatching control system can be a master station. The master station calls to obtain the actual setting of the relay protection device set in the substation. The function of the master station calling to obtain the actual setting of the relay protection device set in the substation is not defined in the IEC104 protocol. The present invention implements this function by extending the type of the application layer of the IEC104 protocol and nesting the IEC103 protocol in IEC104. Specifically, the front-end acquisition continues to use the application protocol control information APCI of the IEC104 protocol, and the application service data unit ASDU part directly uses the ASDU of the IEC103 protocol to realize the data transmission between the dispatching control system and the relay protection device in which IEC104 nests the IEC103 protocol.

[0050] In this implementation, the data transmission between the dispatching control system and the relay protection device based on IEC104 and IEC103 protocol is effectively improved the data transmission efficiency and quality of operation and maintenance work.

[0051] In this embodiment, the database is set in the dispatching control system. The database pre-stores the reference constant value corresponding to the target area.

[0052] In another embodiment of the present invention, remotely modifying the setting of the relay protection device according to the target setting includes: the dispatching control system sends a message for modifying the setting to the master station front-end program, and the master station front-end program sends the message to the relay protection device.

[0053] Based on the previous embodiment, in another embodiment of the present invention, before the dispatching control system sends the modified set value message to the master station front-end program, it also includes: after the dispatching control system and the relay protection device are pre-calibrated successfully, the dispatching control system sends the modified set value message to the master station front-end program.

[0054] In this embodiment, exemplarily, the dispatching control system, for example, the master station sends a message to modify the set value to the master station front-end program, the front-end program sends a message to the relay protection device in the substation, after the pre-calibration result of the relay protection device is successful, the master station human-machine interface displays the pre-calibration result, and then the master station sends a message to modify the set value execution to the master station front-end program, the master station front-end program sends a message to the relay protection device in the substation, after the relay protection device in the substation executes successfully, it returns a message to the master station human-machine interface to display the execution result.

[0055] By pre-calibrating the dispatching control system and the relay protection device and displaying the pre-calibration results on the master station human-machine interface, the reliability of communication between the dispatching control system and the relay protection device can be effectively improved, and the operator can promptly understand whether the communication between the dispatching control system and the relay protection device is normal.
