摘要： 针对难以精确实现对永磁断路器分合闸电容器组恒流充电控制,提出了一种模糊恒流充电技术。在分析分合闸电容器组恒流充电工作特性的基础上,构建了恒流充电的电流偏差e、偏差变化率e_c和输出量u的隶属度函数与模糊控制规则,建立了替代复杂的模糊控制算法的二维查询表格,可有效提高模糊恒流控制系统的实时性。搭建了恒流充电系统的Matlab仿真模型与智能控制单元,仿真和实验结果表明,该方法实现了分合闸电容器组恒流充电控制,有效地提高了电容器组的充电快速性和使用寿命。

Abstract: In order to realize the precise control of breaking and making capacitors constant current charging for the permanent magnet (PM) circuit breaker, a fuzzy constant current charging technology of breaking and making capacitors is put forward. On the basis of analyzing the working characteristics for breaking and making capacitors constant current charging, the membership functions of current deviation e, deviation changing rate e_c and output variable u for breaking and making capacitors constant current and fuzzy control rules are set up. The establishment of a two-dimensional lookup table replacing the complex fuzzy control algorithm can effectively improve the fuzzy constant current control system in real time. Matlab simulation model and intelligent control unit of constant current charging system for PM circuit breaker are built and developed. The simulation and experiment results show that the fuzzy control method can achieve the constant current charging control of breaking and making capacitors and can effectively improve the charging speed and lifetime of PM circuit breaker capacitors.

Key words: PM circuit breaker, breaking and making capacitors, fuzzy constant current charging, fuzzy algorithm and two-dimensional table, intelligent control unit
