Intelligent series compensation device

The utility model discloses an intelligent series compensation device. Monitoring device, Voltage at two ends of a capacitor Cm acquired by the voltage transformer PT is processed by the filter circuit and then is output to the microcontroller MCU. The microcontroller MCU sends digital voltage signals and position information to the dispatching center through the wireless communication module. Themonitoring and scheduling center monitors voltage changes at the two ends of the capacitor. Knowing working conditions of series devices, Voltage at two ends of a capacitor is increased when a short-circuit fault occurs in a power distribution network line; The capacitor is cut off from the power distribution network, the dispatching center can know that the power distribution network breaks downthrough voltage change, the information comprises the position information of the series device, and the dispatching center can accurately position the fault position, quickly arrive at the accidentposition to process the fau
