摘要
针对综合电力系统(Integrated Power System,简称IPS)包含大量非线性元件等特点,在传统电力系统混合仿真原理基础上提出时步保持算法,利用EMTDC软件的用户自定义模块及其与Matlab兼容的功能,在两种软件中分别搭建不同网络的仿真模型并采用不同步长进行仿真。利用该方法不用计算解耦后系统的等效网络,在未能获取含有大量开关器件及特殊元件的电磁网络诺顿等值参数的情况下仍能实现多步长混合仿真。对比验证了该方法的精确度、观测系统动态特性和可操作性。
In accordance of the characteristics of IPS with many non-linear elements, this paper introduces a time-step-holding method for the simulation of integrated power system （IPS） based on traditional hybrid simulation theories, which makes full use of EMTDC＇s function of self-define component and its compatibility with Matlab to build models for different networks with the two kinds of software using different time steps respectively. In this way, the obtaining of equivalent decoupled network becomes unnecessary, and hybrid simulation may be undertaken without the Norton equivalent parameters of electromagnetic network being worked out. Comparison with standard simulating results demonstrates the precision, the observability of system dynamics and the feasibility of this method.
