基于数值积分代换的电力电子与电力系统电磁暂态联合仿真接口
Numerical Integration Substitution Based Power Electronic and Power System Electromagnetic Transient Co-simulation Interface
摘要
Abstract
The existing electromagnetic transient co-simulation system interfaces face limitations in terms of stability and difficulty in obtaining accurate equivalent parameters,which affects the precision and stability of simulations for power electronics and power systems.This paper incorporates inductors and capacitors between power electronic devices and power grid systems into the simulation interface by equivalent numerical integration,and proposes a co-simulation circuit interface model based on numerical integration substitution.Through stability and error analysis,the stability criteria for the co-simulation system are provided.Furthermore,the characteristics and applicability of the proposed interface are compared with those of the ideal transformer and other circuit interfaces.Two simulation case studies are conducted to verify the feasibility and effectiveness of the proposed co-simulation interface.关键词
