基于ETAP的继电保护整定及优化

ANALYSIS OF RELAY PROTECTION AND COORDINATION BASED ON ETAP

随着石化装置规模的不断扩大,对供电的可靠性和稳定性要求更加苛刻,由此带来的继电保护整定和校验工作也越来越复杂,而借助工程软件可以极大提高整定效率和质量。对具体工程实例进行继电保护定值计算和校验,并利用ETAP进行保护曲线配合分析和定值优化调整。实际运行效果表明,借助ETAP能快速准确地输出TCC曲线,定值及曲线调整方便,可以极大地提高整定效率和质量。

With the capacity expansion of petrochemical units,the requirements for the reliability and stability of power supply become more stringent,and the relay protection setting and verification become more and more complex.The use of simulation and analysis software of power system can greatly improve the efficiency and quality of this work.This paper carries out the relay protection settings calculation and verification,coordinates the protection curves in ETAP,and optimizes the settings.The actual operation results indicate that ETAP can output the TCC curves quickly and accurately,and it is convenient to change the settings and curves.ETAP can greatly improve the efficiency and quality.
