摘要
针对配电网日益严重的电能质量问题,从无功功率波动角度加以分析;介绍了比常用无功补偿装置更具优势的静止同步补偿器(STATCOM)的dq0系统数学模型及瞬时无功功率检测理论,并推导出了其解耦控制方程。最后基于MATLAB构建了35 kV配电网,对常见电能质量问题进行了仿真,得出STATCOM对配电网电能质量改善有显著效果。
The problem of increasingly serious power quality in distribution network is analyzed from the perspective of reactive power fluctuation.The instantaneous reactive power detection theory and dq0 STATCOM mathematical model are described,which has a comparative advantage among the common reactive power compensation equipment,and derived out its decoupling control equations.35 kV distribution network is constructed based on Matlab,and common power quality issues are simulated.It is concluded that STATCOM could greatly improve the power quality which has a good guide for STATCOM in the power distribution network.
