配电静止同步补偿器模糊控制的优化设计

Optimal design of fuzzy control for distribution static synchronous compensator

针对复杂配电静止同步补偿器模糊控制参数难以调整的问题,建立了基于直接电流控制和简化FBD检测法的配电静止同步补偿器数学模型,在传统模糊PI控制原理的基础上,提出了基于混沌粒子群算法的模糊控制参数优化设计方法。仿真和试验结果表明,该优化方法能精准控制直流侧电压并使其抗干扰能力增强,同时使补偿电流能够快速准确跟踪补偿电流指令值,大幅提高了控制效果。

For problem that fuzzy control parameters of complex distribution static synchronous compensator is difficult to adjust, mathematical model of distribution static synchronous compensator based on direct current control and simplify FBD detection method was built, and an optimal design method of fuzzy control parameters based on chaos particle swarm algorithm was proposed on the basis of analysis of traditional fuzzy PI control principle. Results of simulation and experiment show that the optimization method can control DC voltage precisely and enhance noise immunity, meanwhile make the compensating current track the compensation current command value quickly and accurately, which improve the control effect significantly.
