A Novel Control Method for Magnetic-Valve Controllable Reactor

Accurate and swift control is the base of operating magnetic-valve controllable reactor (MCR). In this paper, a novel control method for the MCR is proposed, this method uses a flexible algorithm to get a synchro signal from line-to-line voltage by special signal process first, and then divides the synchro signal into six controllable trigger pulses precisely, operate the MCR according to associated roles that stored in memory in advance; the algorithm can be implemented by hardware easily and the requirement of high performance can be met. Based on the algorithm, a model of MCR is introduced and the algorithm is implemented by FPGA and PLC mainly. The application of the system shows that the new device has quick response, good precision, well ability of anti-electromagnetic disturbance, strong adaptability of the environment and can also operate stably for a long time.
