摘要
Abstract
In order to better simulate external characteristics of actual grid using power quality testing supply , this pa-per proposes power quality simulation method based on equivalent model of power grid .In view of similarity theory , the similarity degree d is proposed as an index to evaluate the similarity between power quality simulated by testing supply and the prototype .With regard to H-bridge cascaded inverter topology , voltage source virtual impedance con-trol strategy based on repeated study control is also proposed in this paper .It can simulate external characteristics of actual grid in fundamental situation , meanwhile it embraces high credibility .Ultimately , feasibility of proposed control strategy and index is verified by simulation .关键词
