电力二次系统接地及抗干扰方法研究

Research on Grounding and Anti-interference Method of Power Secondary System

电力系统二次系统接地操作过程中,需要根据工作强度和电磁环境,实施合理的变电站检修从A座分析,及时调整线路系统中的变压器短路故障问题,结合实际雷电侵扰情况,及时调整接地设备的故障问题,实施二次系统的有效应用。分析干扰方法造成的误动,对电力系统实施自动化、设备系统参数实施二次接地模式进行分析,准确判断二次系统采取的有效通信系统应用,确定具体的数据参数系统标准,确定控制模式和保护系统方法。

In the process of power system secondary system grounding operation,it is necessary to implement reasonable substation maintenance according to the working intensity and electromagnetic environment,analyze from block a,adjust the transformer short-circuit fault in the line system in time,adjust the fault of grounding equipment in time in combination with the actual lightning interference,and implement the effective application of the secondary system.Analyze the maloperation caused by the interference method,analyze the power system implementation automation,equipment system parameter implementation secondary grounding mode,accurately judge the effective communication system application adopted by the secondary system,determine the specifi c data parameter system standard,determine the control mode and protection system method.
