摘要
基于Matlab/Simulink仿真软件所研发的实时仿真器,在电力系统继电保护装置测试环节有较高的实用价值。Simulink元件库所提供的动态负荷元件在特定的仿真工况下,其外特性呈现剧烈震荡的现象,不利于被测试装置稳定工作。基于动态负荷元件的工作原理,分析了动态负荷外特性异常的形成机理,并提出了相应的改进策略。在仿真测试平台上搭建算例进行试验验证,试验结果表明该改进控制策略是有效可行的。
The real time simulator based on Matlab/Simulink simulation software has high practical value in power system relay protection test. The dynamic load components provided by the Simulink component library under the specific simulation conditions, the external characteristics of the phenomenon of severe shock, is not conducive to the stability of the test device. Based on the working principle of dynamic load components,this paper analyzes the forming mechanism of the abnormal characteristics of dynamic load, and puts forward the corresponding improvement strategy. The simulation results show that the improved control strategy is effective and feasible.
