摘要

随着静止无功补偿器（static synchronous compensator

STATCOM）的结构多重化

使得其负载电流测量点和补偿注入点因所处位置不同

从而产生较大的检测差异。针对上述问题

文中提出一种改进型ip-iq算法

分别从测量点和补偿点引入电压相位信息

通过设置相位补偿角和比例谐振（PR）控制器

消除因两处电压相位和幅值差异引起的检测误差

提高检测精度。理论分析和仿真结果验证了所提方法的有效性。

Abstract

With the diversification of the structure of static var compensator（STATCOM）

detecting point of load current and the point of injection compensation varies by location

resulting in a large difference is detected.To solve this problem

this paper proposes an improved ip-iqalgorithm

and introduced voltage phase information from the detecting point and compensation point.Eliminating detection error from the difference of voltage phase and amplitude by set up phase compensation angle and PR controller.Theoretical analysis and simulation results show the effectiveness of the proposed methods.
