DETAILED DESCRIPTION

[0041] For the purpose of facilitating the understanding of the present disclosure, the present disclosure will be described more fully below with reference to the accompanying drawings. The preferred embodiments of the present disclosure are shown in the drawings. However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the present disclosure is more thorough and complete.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present disclosure belongs. The terminology used in the description of the present disclosure herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure.

[0043] As used herein, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise. It should also be understood that the term "comprising" and / or "comprises", when used in this specification, specifies the presence of stated features, integers, steps, operations, elements, and / or components, but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof. Also, as used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0044] The circuit breaker control method provided by the embodiments of the present disclosure can be applied to the application environment as shown in FIG. 1. Wherein, the controller 101 and the unit 102, the circuit breaker 103 can be directly or indirectly connected through wired or wireless communication mode, for example, through the power grid 104.

[0045] For example, the circuit breaker control method is applied to the controller 101, the controller 101 acquires the actual speed information of the target unit 102, and generates a frequency signal when the actual speed information of the target unit 102 meets the pre-set speed condition; then, the controller 101 acquires the state information of the target circuit breaker 103, and generates a pulse signal when the state information meets the pre-set state condition; finally, the controller 101 generates a trip signal according to the pulse signal and sends it to the target circuit breaker 103 to control the target circuit breaker 103 to open.

[0046] In some embodiments, a circuit breaker control method is provided, and this embodiment is exemplified by the circuit breaker control method applied to a controller, as shown in FIG. 2, the circuit breaker control method comprises steps S100-S400.

[0047] S100, obtaining actual speed information of a target unit.

[0048] The target unit can be a generator set for power supply of a power grid, and the actual speed information of the target unit is used to indicate an actual speed value of a generator rotor in the target unit, which is usually expressed in revolutions per minute (rpm). The speed value of the generator rotor can reflect the running state of the target unit when it is working, including the output power and frequency of the generator in the target unit. The higher the speed value of the generator rotor, the more electric energy generated by the generator in the target unit, but it will also increase the wear and tear and energy consumption of the target unit. By monitoring the actual speed information of the target unit, the running condition of the generator in the target unit can be understood, problems can be found in time and adjusted and maintained to ensure the safe and stable operation of the target unit.

[0049] As an example, the controller can use a speed governor speed measuring device to collect the actual speed information of the target unit. The speed governor speed measuring device measures the speed value by collecting signals generated by speed sensors on the generator rotor in the target unit. These speed sensors are usually installed on the rotor of the generator in the target unit and are connected to the speed governor speed measuring device to transmit the speed signals to the speed governor speed measuring device for processing and analysis. The speed governor speed measuring device can accurately measure the actual speed value of the generator rotor in the target unit by analyzing these speed signals, and the actual speed information is sent to the controller.

[0050] Alternatively, the controller can use a unit-side speed measuring device to collect the actual speed information of the target unit. The unit-side speed measuring device is equipped with two toothed disc speed measuring probes and can monitor the actual speed value of the generator rotor in the target unit in real time through external speed pulse sensors and voltage transformer signals. The unit-side speed measuring device serves as a backup for the speed governor speed measuring device. When the speed governor speed measuring device fails and cannot send the actual speed information to the controller, the unit-side speed measuring device accurately measures the actual speed value of the generator rotor in the target unit through pulse sensors and other devices, and the actual speed information is sent to the controller.

[0051] S200, when the actual speed information meets the pre-set speed condition, generating a frequency signal.

[0052] The speed condition can be a range for limiting the speed value of the generator rotor in the target unit, and the frequency signal is used to indicate the working frequency information of the target unit corresponding to the speed condition.

[0053] The working frequency information of the target unit is used to indicate the frequency of the AC power output by the target unit, which is usually expressed in hertz (Hz). The working frequency information of the target unit can reflect the stability and operating state of the target unit. Changes in the working frequency information can affect the operation of the target unit and various devices in the power supply system in which the target unit is located, including generators, transformers, motors, etc. If the frequency of the AC power output by the target unit deviates from the normal set frequency range value, it can cause the target unit and the devices in the power supply system to malfunction or be damaged.

[0054] S300, obtaining the state information of the target circuit breaker, and generating a pulse signal based on the frequency signal when the state information meets a pre-set state condition.

[0055] The state information of the target circuit breaker refers to the state information of the contacts of the circuit breaker, which can specifically be used to indicate the position of the contacts of the circuit breaker. When the contacts of the circuit breaker are in the closed position, the power supply system in which the target unit is located can normally supply power to the power grid. When the contacts of the circuit breaker are in the open position, the circuit of the power supply system in which the target unit is located is disconnected.

[0056] The pre-set state condition can be used to limit the position of the contacts of the circuit breaker.

[0057] The pulse signal refers to a set signal. When the controller generates the pulse signal, the controller can set Q15.7 to 1, where Qm.n represents that the data in the controller is represented by m bits for the integer part and n bits for the decimal part, a total of m+n+1 bits are needed to represent the data, Q15.7 represents data with 15 bits for the integer part and 7 bits for the decimal part, and the controller sets it to 1.

[0058] S400, generating a trip signal according to the pulse signal and sending it to the target circuit breaker to control the target circuit breaker to disconnect.

[0059] The trip signal is used to control the target circuit breaker to place the contacts in the open position to control the circuit of the power supply system in which the target unit is located to be disconnected to prevent circuit damage or fire.

[0060] In the above circuit breaker control method, the controller can monitor the rotational speed value of the rotor of the generator in the target unit in real time, and when the rotational speed value is in a specific rotational speed value range, the actual frequency of the AC power output by the target unit is obtained. Subsequently, when it is determined that the contacts of the target circuit breaker are in the position required by the pre-set state condition, a trip signal is automatically generated to control the circuit breaker to disconnect the circuit, thereby realizing intelligent opening control of the circuit breaker. The above circuit breaker control method does not require manual control, reduces labor costs, and promotes the optimal allocation of power resources.

[0061] In some embodiments, the rotating speed condition comprises that the actual rotating speed information indicates that the actual rotating speed value of the target generator set does not reach a first proportion of the preset rotating speed value, or the actual rotating speed information indicates that the actual rotating speed value of the target generator set is not zero.

[0062] For example, the step S200 comprises: generating the frequency signal when the actual rotating speed information indicates that the actual rotating speed value of the target generator set does not reach a first proportion of the preset rotating speed value, or the actual rotating speed information indicates that the actual rotating speed value of the target generator set is not zero.

[0063] The first proportion of the preset rotating speed value can be 90% of the preset rotating speed value.

[0064] After obtaining the actual rotating speed value of the rotor of the generator in the target generator set, the controller further determines whether the actual rotating speed value of the rotor of the generator reaches a first proportion of the preset rotating speed value, and if not, generates the frequency signal, and if so, further determines whether the actual rotating speed value of the rotor of the generator is zero, and if not, also generates the frequency signal.

[0065] In some embodiments, the state condition is that the target circuit breaker is in the closed position.

[0066] For example, the step S300 comprises: generating the pulse signal based on the frequency signal when the state information indicates that the target circuit breaker is in the closed position.

[0067] After obtaining the state information of the contact of the circuit breaker, the controller determines whether the contact of the circuit breaker is in the closed position, and if so, generates the pulse signal, and if not, does not generate the pulse signal.

[0068] In some embodiments, the circuit breaker control method further comprises:

[0069] receiving a control signal, and controlling the target circuit breaker to open according to the control signal;

[0070] The step 208 comprises: generating a trip signal and sending the trip signal to the target circuit breaker to control the target circuit breaker to open when no control signal is received within a preset time length after the pulse signal is generated.

[0071] The control signal can be a low frequency to interlock GCB open signal, and the control signal is used to instruct the contact of the target circuit breaker to open to disconnect the circuit of the power supply system in which the target generator set is located.

[0072] The preset time length can be, for example, 2 seconds.

[0073] The controller automatically generates the trip signal to control the target circuit breaker to open if the controller does not receive a control signal from the worker externally initiated to control the target circuit breaker to open within a preset time period after the pulse signal is generated.

[0074] In some embodiments, the circuit breaker control method further comprises:

[0075] The generation of the trip signal is stopped when the reset signal is obtained within the preset time period.

[0076] The reset signal refers to resetting the data set to 1 by the controller according to the pulse signal to 0.

[0077] The controller stops generating the trip signal if the reset signal that resets the data set to 1 by the controller according to the pulse signal to 0 is detected within a preset time period after the pulse signal is generated.

[0078] In some embodiments, the method for generating the reset signal comprises:

[0079] The actual speed information of the target unit is continuously obtained within a preset time period after the pulse signal is generated, and the reset signal is generated when the actual speed information indicates that the actual speed value of the target unit reaches a first proportion of the preset speed value, or the actual speed information indicates that the actual speed value of the target unit is zero.

[0080] The controller continuously obtains the actual speed information of the target unit within a preset time period after the pulse signal is generated, and determines whether the newly obtained actual speed value of the generator rotor reaches a first proportion of the preset speed value, and generates the reset signal if the actual speed value of the generator rotor reaches the first proportion of the preset speed value, and further determines whether the actual speed value of the generator rotor is zero if the actual speed value of the generator rotor does not reach the first proportion of the preset speed value, and generates the reset signal if the actual speed value of the generator rotor is zero.

[0081] It should be understood that although each step in the flowchart involved in each of the above embodiments is displayed in sequence according to the direction of the arrow, these steps are not necessarily executed in sequence according to the direction of the arrow. Unless otherwise specified herein, the execution of these steps is not strictly limited in sequence, and these steps can be executed in other sequences. Moreover, at least part of the steps in the flowchart involved in each of the above embodiments can include multiple steps or stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution sequence of these steps or stages is not necessarily sequential, but can be executed in rotation or alternation with at least part of other steps or stages in other steps.
