摘要
相控开关技术可以有效地削弱电网各类负载投切操作引起的系统暂态过程,是建设智能电网的重要技术之一。真空开关选相操作的技术关键是控制真空开关机构的运动特性,实现真空开关在不同环境下的动作时间稳定。利用模糊PID自适应控制技术,针对基于永磁机构的真空开关提出一种新型控制驱动方案;并基于TMS320LF2407A处理器实现了新型真空开关永磁机构驱动控制系统的设计。实验研究验明了该控制系统在环境因素变化时可保持合闸时间误差稳定在±0.25 ms以内。
The phase-control switching technology of circuit breakers,which provides an important technical approach for smart grid construction,can effectively mitigate the transient caused by switching operations in power systems.The key technology of phase selections with vacuum switches is to control the operating characteristic of permanent magnetic actuators in vacuum switches,so as to realize a stable operating time for vacuum switches under different environmental conditions.This paper proposed a new type of control-driven program for vacuum switches with permanent magnetic actuators using the fuzzy self-adaptive PID control technology.And the design of this new type of control-driven system for permanent magnetic actuators in vacuum switches was accomplished based on the TMS320LF2407A processor.According to the experimental results,the system can keep the switching time error within ±0.25ms under different environmental conditions.
