基于离散状态事件驱动的电力电子瞬态过程仿真方法
Discrete State Event Driven Based Methods for Transient Simulation of Power Electronic Converters
摘要
Abstract
In order to calculate electromagnetic transients of power electronic systems, non-ideal physical models considering stray parameters of circuits and time delay of control loops are needed for semiconductor switching device. In this case, the mathematical models describing power electronic system exhibit high-order nonlinearity and tend to be highly rigid. The numerical solution methods through the conventional differential equations shall bring about the problems of long simulation time and poor numerical stability. Thus, this paper puts forward the improved methods for transient simulation of power electronic converters based on discrete state event driven (DSED) methods. These methods use the variation of state variable as the calculation basis rather than the variation of simulation time. It is demonstrated the methods could reduce simulation time effectively and solve the stiff problem of ordinary differential equations, which ensure numerically stable of the simulation.关键词
