乙烯变电所继电保护整定计算分析

Calculation and Analysis of Relay Protection Setting in Ethylene Substation

摘要: 继电保护是电力系统的重要组成部分，它能快速切除故障构成了电力系统的第一道防线，为电力系统的安全稳定运行提供了强有力的保障。电力系统对继电保护提出了可靠性、选择性、灵敏性、速动性的要求，合理的继电保护整定计算是满足“四性”要求的关键。本文结合乙烯变电所 6 kV 开关柜更新改造，对乙烯变电所的继电保护整定计算进行分析，保证了电力系统的安全稳定运行。

Abstract: Relay protection is an important part of the power system, it can quickly remove the fault constitutes the first line of defense of the power system, for the safe and stable operation of the power system to provide a strong guarantee, power system puts forward the requirements of reliability, selectivity, sensitivity and quickness for relay protection, reasonable relay protection setting is the key to meet the "four" requirements. Combined with the renovation of 6kV switchgear of ethylene substation, this paper analyzes the relay protection setting calculation of ethylene substation, and ensures the safe and stable operation of the power system.
