220kV智能变电站继电保护配置方案研究

Research on Relay Protection Configuration Scheme of 220 kV Intelligent Substation

变电站的运行过程会受到自然因素以及外力的影响,造成电气故障,引起电力安全事故。继电保护装置能够对电气故障起到一定的防护作用,确保变电站电网的安全性和可靠性。文章阐述了智能变电站的继电保护装置的构成,并以220 kV变电站为例,论述了智能变电站继电保护装置的技术要求、方案设计。

The substation operation process will be affected by natural factors and external forces,resulting in electrical faults,causing power safety accidents. Relay protection device can play a certain role in protection against electrical faults,and ensure the safety and reliability of substation power grid. The constitution of relay protection device in intelligent substation was analyzed and expounded in this paper. Taking 220 kV substation as an example,the technical requirements and scheme design of relay protection device in intelligent substation were expounded.
