摘要/Abstract

摘要： 针对大量分布式电源接入后的工业园区配电网电压跌落检测问题进行深入分析,开展了基于多dq坐标旋转变换的正负序分离法和基于S变换法的详细设计研究。最后,为验证方法的正确性,在MATLAB/Simulink中搭建了仿真模型,结果表明基于多dq坐标旋转变换的正负序分离检测法更满足电压恢复控制的实时要求,为工程设计奠定理论基础。

关键词: 电压跌落, 多dq坐标系旋转变换, S变换, 动态电压恢复

Abstract: The problems of voltage sag detection of the industrial park distribution network after a large number of DGs were analyzed.The detailed design research based on the positive-negative sequence separation method of multi-dq coordinate rotation transformation and the S-transform method was carried out.Finally,in order to verify the correctness of the method,a simulation model was built in MATLAB/Simulink.The results show that the positive and negative sequence separation detection method based on multi-dq coordinate rotation transformation meets the real-time requirements of voltage recovery control,which lays a theoretical foundation for engineering design.

Key words: voltage sag, multi-dq coordinate rotation transformation, S-transform, dynamic voltage recovery
