摘要(Abstract)：
应用MATLAB软件的PowerSystemBlock_Set和Simulink仿真工具 ,对一组电磁式电压互感器的铁磁谐振规律进行了仿真研究。分析、比较了二次侧微电脑消谐和高压侧中性点经电阻接地消谐两种措施的消谐效果。提出了防止中性点不接地系统PT谐振的几点建议
Through the application of Power System Block_Set and Simulink based on MATLAB software, ferromagnetic resonances of a group of electromagnetic potential transformers in the isolated neutral system are simulated and studied. This paper also analyzes two kinds of eliminating resonance methods including microcomputer resonance eliminator connected in the tertiary winding and nonlinear resistance between primary neutral point of PT and ungrounded. In the end, some protective measures and suggestions are proposed.
