摘　　要：为解决有源电子式电流互感器高压侧供电不稳定、"死区"等问题,提出一种双路供电系统,由母线取能和激光供能完成。设计了一种适用于母线大电流时供电的线圈,并针对激光器存在寿命短和可靠性差等问题,给出了根据信号采集系统的电能需求使用模糊PID控制算法进行动态调节激光发射功率,从而提高激光器的使用寿命,通过仿真分析,进一步说明了模糊PID控制能很好的调节激光器,最终保证了高压侧供电稳定,对高压侧供电电源研究提供了重要参考。In order to solve the problems of unstable power supply and "dead zone" in the high voltage side of active electronic current transformer, a double-circuit power supply system is proposed, which is completed by bus and laser power supply. Aiming at the problems of short lifetime and poor reliability of lasers, a fuzzy control algorithm is proposed to dynamically adjust the laser transmitting power according to the power demand of the signal acquisition system, so as to improve the service life of lasers. Through simulation analysis, it is further illustrated that the fuzzy control can control lasers well, and finally ensure reliable power supply at the high voltage side. Power supply research provides important reference.
