Embodiment Construction
[0038] figure 1 It is a flowchart of a method for eliminating ferromagnetic resonance in an active compensation system provided by an embodiment of the present invention.
[0039] see figure 1 , a ferromagnetic resonance elimination method in an active compensation system provided by an embodiment of the present invention is used to eliminate ferromagnetic resonance, which can shorten the resonance elimination time, reduce the resonance elimination cost, and improve the resonance elimination efficiency to ensure power distribution The safe and stable operation of the network.
[0040] Specifically, the elimination method includes the following steps:
[0041] S1. Detect the neutral point voltage of the distribution network system according to the predetermined detection cycle;
[0042] After the active compensation system is used to compensate the voltage of the distribution network system, the active compensation system exits the compensation state, and the system returns ...
