摘要
电压源逆变器在可再生能源并网、变频调速系统、不间断电源(uninterrupted power source,UPS)等领域得到了广泛的应用。文章针对以电压源逆变器并网的微源,研究其典型的控制方式,以电压源逆变器电路模型为出发点,基于Digsilent平台搭建电压源逆变器典型控制器模型。在风、光、储微电网模型上进行验证,并对典型控制器模型的控制过程进行仿真分析,仿真结果表明,控制器模型基本能够满足微电网存在的并网运行和离网运行两种工况的正常运行要求。
In renewable energy grid,variable frequency speed regulation system,uninterruptible power source and other fields voltage source inverter has been widely used.Aiming at the micro source of voltage source inverter,the typical control mode is studied.Starting from the circuit model of voltage source inverter,a typical controller model of voltage source inverter based on Digsilent is built.The proposed model is validated on a micro grid model with a combination of wind,light,and storage.The control process of typical controller model is simulated and analyzed.The simulation results show that the controller model can basically meet the requirements of the 2 operating conditions of grid connected operation and off grid operation.
