摘 要:变电站是整体电力系统的核心组成部分,其一次与二次设备的安全运行直接关系着整体电力系统的安全性与稳定性。当前阶段很多变电站的巡检工作依旧是以人工为主,这很容易因具体操作人员的个人失误而导致继电保护出现一定的运检故障问题,这种情况下,加强变电站继电保护运检防误技术的应用已经势在必行。该文就变电站继电保护运检防误要点、防误技术设计、主动式综合防误技术、技术应用措施进行了分析与论述。

Abstract: Substation is the core component of the overall power system. The safety operation of primary and secondary equipment is directly related to the safety and stability of the whole power system. At present, the patrol inspection work of many substations is still manual, which can easily lead to certain operation and inspection failures of relay protection due to the personal mistakes of specific operators. In this case, it is imperative to strengthen the application of relay protection operation and error detection technology in substations. This paper analyzes and discusses the key points, technical design, active comprehensive anti-error technology and technical application measures of relay protection in substation.
Key Words: Substation; Relay protection; Anti-error technology of transportation and inspection; Baseline algorithm
變电站继电保护运检防误技术因其本身的突出优势已经逐渐实现了在变电站运检中的应用,并且取得了较好的效果,进一步提升了变电站本身的稳定性与安全性,使其能够持续的运行为民众提供更加优质的电力产品。因此需给予其充足的重视,使其得到较为广泛的应用,降低运检中系列故障问题的同时,为电力企业创造更大的经济效益。
1 变电站继电保护运检防误要点
传统变电站在运行过程中会受到外界各种因素的影响而出现较多的安全事故,为减少该类事故的发生,应注意以下运检防误要点:其一,考虑到当前阶段变电站运检范围逐步扩大,应当建设完善、规范、先进的运检防误系统,并完善继电保护系列操作;其二,在设计规范操作手册时,建立变电站继电保护防……
