Provided is a reactive power compensator controller. A CAN bus of a CAN communication module and a TMS320F type DSP controller chip are adopted. The host and slave computer network structure designs of a host computer plus a DSP controller are adopted. The real-time data information of a voltage sensor, a current sensor, a temperature detection device, a voltage zero crossing detection device and a power supply detection, acquisition and compensation device are employed. The DSP controller is utilized to achieve high speed and accurate data processing. A CPLD, a photoelectric conversion module I and a photoelectric conversion module II send synchronous trigger pulse signals through fibers to a high potential plate so that a thyristor valve unit is triggered to carry out reactive compensation for a power distribution network. The CAN communication module is connected to the host computer and the DSP controller by means of a communication mode of a CAN bus technology to achieve highly efficient transmission of data and man-machine interaction. Moreover, a good control effect is achieved. The reactive power compensator controller is suitable for various reactive power compensators.
