摘要
根据静止同步补偿器的数学模型,提出其无功电流微分几何非线性控制方法,讨论非线性控制方法中零动态稳定性问题,在其基础上提出了兼顾有功电流调节性能的优化策略,最后用Matlab进行仿真分析,仿真结果验证了数学模型的正确性,同时表明了非线性控制的优化策略的有效性,达到了良好的动态无功补偿效果。
A transient mathematic model of StatCom is presented based on switching function, and one nonlinear control strategy of StatCom＇s reactive current based on the theory of differential geometry are proposed. Then the stability of zero dynamics on nonlinear control strategy is discussed. Based on the theory of differential geometry , one optimized nonlinear control are proposed. Finally , the results of simulation and analysis about two control strategies are given by using Matlab, which validate the mathematic model of StatCom and shows the regulate performance of optimized control is superior to that of traditional nonlinear control when the direction of referenced input current was changed, and the effect of compensating reactive power is satisfied.
