摘　　要：电力系统的快速发展对继电保护提出了更高的要求,继电保护整定计算是继电保护系统中非常重要的组成部分,也是继电保护能否发挥功能的重要保障。定值整定是否正确直接关系到继电保护的动作正确与否。只有充分发挥继电保护装置的作用,才能在电网发生故障时快速、正确地做出反应,保证整个电网的安全运行。主要对火电厂6 kV系统继电保护的保护配置和计算步骤做了初步介绍。The rapid development of the power system puts forward higher requirements for relay protection. Relay protection setting calculation is a very important part of the relay protection system, and it is also an important guarantee for the performance of the relay protection. Whether the setting is correct or not is directly related to the correctness of the relay protection action. Only by giving full play to the role of relay protection devices and responding quickly and correctly when the power grid fails can the safe operation of the entire power grid be ensured. The protection configuration and calculation steps of 6 kV System Relay Protection in thermal power plant are introduced.
