继电保护技术原则在变电站二次设计中的应用

经济的快速发展使我国各行各业的发展随之加快,人们在日常生活和工作中的用电量大幅度增长,迫使电力系统的装配容量不断增加、网架结构越来越复杂,从而带来更多的供电设施故障和事故的可能,影响电网的安全生产.继电保护是保证电力系统安全稳定运行的重要屏障,是电力系统不可缺少的组成部分.本文主要就继电保护技术原则在变电站二次设计中的应用进行简要的探析.

Application of relay protection technical principle in substation two times design

The rapid development of economy makes the development of all walks of life in China will be accelerated, people in daily life and work of electricity consumption growth, assembly capacity forced power system is increasing, the grid structure is becoming more and more complex, resulting in more power supply facilities failure and accident may affect the safety of power grid production.Relay protection is an important barrier to ensure the safe and stable operation of power system, and is an indispensable part of the power system.In this paper, the application of relay protection technology principle in the two design of substation is briefly discussed.
