Abstract

The invention provides a method and a device for simulating a power electronic system in order to solve the problem of low speed of power electronic system simulation in the prior art. The method comprises the following steps of: calculating variation of a topological structure caused by starting and stopping operation of a simulation system by using a Petri Net matrix model; updating a state equation of a continuous sub system of the simulation system according to information of the variation of the topological structure; and calculating the state equation of the continuous sub system to determine a value of a state variable of the simulation system. By using the technical scheme, the power electronic system simulation can be carried out efficiently.

Description

Power electronic system simulation method and device technical field The invention relates to a power electronic system simulation method and device. Background technique In the field of power electronics and power train simulation, the continuity of the system is broken due to the switching action of power electronic devices. Therefore, power electronics and electric drive systems are typical hybrid systems composed of discrete subsystems and continuous subsystems. In addition, due to the nonlinear components in the system (such as the saturation of electromagnetic components) and the nonlinear model of the system equipment (such as the asynchronous motor model), power electronics and electric drive systems are usually nonlinear systems. For the system-level simulation of the above-mentioned nonlinear hybrid system, the core technology or technical difficulties mainly include the following three points: 1. Modeling and simulation of continuous subsystems; 2. Modelin...
