级联多电平换流器的高效仿真模型
Efficient Modeling for Cascading Multilevel Converters
摘要
Abstract
The cascading Multilevel Converter is a promising converter topology in both fields of Flexible AC transmission systems (FACTS) and Flexible High Voltage Direct Current (HVDC) Transmission. Since this topology is based on a large amount of cascading Sub-Modules, it contains many independent switch branches. If this topology is simulated by the detailed device modeling in the EMTP-type program (such as PSCAD/EMTDC), the time consumed in a single simulation instance can be so long that it becomes an obstacle in the research and design process. An modeling method, based on the EMTP principle invented by Dommel H.W. , for cascading multilevel converters was proposed in this paper which can efficiently solve this problem. The principle behind this method is clear, thus simulation results based on the proposed method are reliable. Validation simulation in PSCAD/EMTDC was provided. The simulation results show that the response of the proposed modeling method coincide with detailed device modeling, meanwhile it has a decided advantage in simulation time consumation.关键词
