摘要
利用MATLAB/simulink仿真软件,以汉川电厂03号启备变的实际参数为例,搭建了启备变的主保护之一的纵差动保护的仿真模型,分别模拟区内、区外故障和不正常运行状态,分析了纵差保护的动作行为,仿真结果验证了该启备变纵差动保护的主要功能。
In this paper,using MATLAB/simulink simulation software,taking the actual parameters of Hanchuan power plant No.03 start up/standby transformer as an example,a simulation model of longitudinal differential protection is established,which is one of the main protections of start up/standby transformer.The internal fault,external fault and abnormal operating condition are respectively simulated.The action behavior of longitudinal differential protection is analyzed.The simulation results verify the main function of the longitudinal differential protection.
