基于Modelica语言的电力系统建模与仿真

摘要

介绍了一种利用Dymola软件进行电力系统建模的新方法。运用该方法对电力系统中各元件分别进行了模块化设计和建模,在对电力系统进行仿真时,只需将对应的元件模块按电气结线图的方式连接即可形成电力系统动态模型。通过2个测试系统,验证了用Dymola搭建的电力系统模型的可靠性,并利用该模型对测试系统进行了动态仿真和稳定性分析。%A Dymola-based power system modeling method is proposed first,whereby the each component of power system has been modularly designed and modeled.The dynamic model for power system simulation can be simply established by connecting the corresponding component modules according to the electrical wiring diagram.Two testing systems are adopted to verify the reliability of the proposed model,meanwhile the model is applied to conduct the dynamic simulation and stability analysis of the testing systems.
