电力系统中的电气二次与继电保护研究

Research on Electrical Secondary and Relay Protection in the Power System

继电保护系统对电力系统的安全运行有重要影响,为满足人们日常生活与生产对电力的需求,有必要深入研究电力系统中的电气二次与继电保护,确保其可充分发挥保护作用。以电力系统中的电气二次与继电保护作为研究对象,在对相关文献进行梳理和结合以往工作经验的基础上,对电力系统中的电气二次与继电保护价值进行简单介绍,然后分析了电力系统中的电气二次与继电保护存在的主要问题,在这一基础上提出电力系统中的电气二次与继电保护策略,包括直流故障处理、PT故障处理、CT故障处理、隐患排查及解决等,以确保电力系统安全、稳定运行,对电网运维管理具有指导和借鉴意义。

The relay protection system has an important impact on the safe operation of the power system.In order to meet the needs of people's daily life and production for electricity,it is necessary to conduct an in-depth re⁃search on electrical secondary and relay protection in the power system to ensure that they can fully play a protec⁃tive role.Taking electrical secondary and relay protection in the power system as the research object,based on combing relevant literature,and combined with previous work experience,the article briefly introduces the value of electrical secondary and relay protection in the power system,then analyzes the main problems of electrical second⁃ary and relay protection in the power system,and on this basis,proposes strategies for electrical secondary and relay protection in the power system,including DC(direct current)fault handling,PT fault handling,CT fault handling,hidden danger investigation and resolution,etc.,to ensure the safe and stable operation of the power system,which is of guiding and reference significance for the operation and maintenance management of the power grid.
