静止无功发生器的控制策略及仿真分析

Control Strategy and Simulation Analysis of Static Reactive Power Generator

随着国家和社会经济的快速发展,配电网负荷变得更具多样性,传统的补偿设备已不能满足用户对电能质量日益增长的需要。针对配电网中存在的无功补偿和谐波抑制问题,本文应用先进的静止无功发生器,采用电流直接控制策略,设计一种基于i_(d)-i_(q)法的无功参考电流的检测方法。搭建了MATLAB仿真模型,仿真结果表明,该装置对谐波有良好的抑制效果,提高了系统的功率因数,维持了系统的稳定性。

With the rapid development of the country and social economy,the load of distribution network becomes more diversified,and the traditional compensation equipment can not meet the increasing demand of power quality of users.Aiming at the problems of reactive power compensation and harmonic suppression in distribution network,this paper designs a reactive power reference current detection method based on i_(d)-i_(q)method by using advanced static reactive power generator,and adopts current direct control strategy.The simulation results show that the device has good harmonic suppression effect,improves the power factor of the system,and maintains the stability of the system.
