基于背靠背ANPC的配电网柔性合环系统建模研究
Research on Modeling of Flexible Closed-loop System of Distribution Network Based on Back-to-Back ANPC
摘要
Abstract
The back-to-back active neutral-point-clamped(ANPC)converter,as the core component of the unified power flow controller of the distribution network,is widely used for the flexible closed-loop operation.However,the ANPC converter has more switching devices and commutation paths,which significantly increases the complexity of modeling.To solve the above problems,an average modeling method of the ANPC converter was proposed.The controlled source equivalent substitution method was used to replace the switching devices.The resistance-capacitance-inductance devices of other parts of the circuit were retained while averaging each branch,which greatly simplified the circuit model of the ANPC converter.On this basis,combined with the flexible control principle based on back-to-back ANPC converters,the average model of a back-to-back ANPC flexible control system was further built.By comparing the simulation results of the switch model and the average model,it was shown that the average model was consistent with the switch model in the internal branch and external characteristics,which verified the correctness and accuracy of the proposed average model and its feasibility in the application of flexible closed-loop system.关键词
