基于模糊控制的电容器投切控制算法

Studies on switching control algorithms for capacitors based on fuzzy control theory

对于现在补偿中比较常用的“九区图法”控制规则进行了分析,指出了这种控制规则在某些系统工况下可能会造成电容器频繁投切的问题.针对这个问题提出了一种运用模糊控制理论的补偿策略,并且进行了算例和仿真分析,验证了应用该控制策略可以避免出现电容器频繁投切的现象.

The tradition voltage wattles control based on the ＂Nine area chart＂ method ,which has some disadvantages such as too many times of adjusting the switching of capacitor and causing oscillation, etc. Fuzzy control strategy is applied in this area. Simulation and practical operation show that the algorithm advances precision of compensation ,and also make powered to be on and off steady.
