摘要

分析了影响DSTATCOM系统稳定性因数

通过提出控制角δ大范围多工况建立DSTATCOM动态控制系统数学模型来实现全局控制

并依据劳斯判据得出了DSTATCOM的非线性控制参数与系统参数之间的稳定性关系。最后分别由控制角δ的大范围多工况模型和瞬态工况模型所得控制策略对DSTATCOM闭环控制系统进行了仿真分析

仿真结果表明大范围多工况模型控制系统突变程度较瞬态工况模型控制系统少

并且恢复到稳定运行时间较瞬态工况模型控制系统短

使系统有更强的稳定性。

Abstract

Factor affecting the DSTATCOM system stability is analyzed

the DSTATCOM dynamic control system mathematical model is set up by way of proposing control angle wide range and multiple conditions to achieve the overall control and the stability relations between DSTATCOM non linear control parameters and system parameters based on LAWES criterion is obtained. Finally

simulation analysis for DSTATCOM closed loop control system is analyzed by the control strategy obtained by the wide range and multiple condition model of control angle and transient condition model respectively. It is shown by the simulation result that the abrupt variation degree of the wide range multiple condition model control system is less compared with the transient condition model

the recovery time to the stable operation is shorter than transient condition model

thus keeping the stability of system stronger.
