摘要
针对不同的研究目的和应用场合,电力系统数字仿真对电力电子装置的建模要求也不尽相同,选取简繁适当的数学模型对系统仿真速度和精度具有重要的意义。文中以可控逆变器为例介绍了电力电子装置的详细模型、开关函数模型和平均值模型,分别采用这3种模型进行仿真,对3种模型的仿真结果进行了比较,进而给出了3种模型的适用范围。
The most detailed and accurate models of power electronic devices are not always necessary depending on the research objectives and scenarios in the power system simulation.Selecting appropriate models is of great significance for the speed and accuracy of simulations.Taking the controllable inverter as an example,the detailed model,switching-function model and average-value model of power electronic devices are discussed and applied in the simulation cases.By comparing simulation results of the three models,the appropriate application range of these models is presented.
