摘要

针对传统瞬时对称分量法在配电网静止同步补偿器（distribution static synchronous compensator

DSTATCOM）不平衡补偿电流检测中存在的一些问题

提出了1种基于改进瞬时对称分量法的新的补偿电流检测方法。它通过构造1个无延迟的旋转向量能准确计算出三相电量的各序分量

不需要进行三角函数计算

而且检测结果不受移相算子的影响。

Abstract

A novel compensation current detection method based on the improved instantaneous symmetrical components is proposed for DSTATCOM to compensate three phase unbalance load current.The principle of the proposed approach is based on the undelayed rotating vector which enables to calculate the positive sequence component

negative sequence component and zero sequence component of the three phase instantaneous variables.The problem of traditional symmetrical components is solved by using the proposed method.The novel current detection is tested by means of detailed simulation using PSCAD/EMTDC

where the performance is validated in the case of severe network fault and in the case of unbalanced load compensation.The results verify the improved instantaneous symmetrical component is more suitable for compensation current detection.
