文档介绍：电网继电保护配置整定计算
摘要
继电保护整定计算是继电保护工作的一项重要内容,对于高压电网的继电保护装置,在系统发生故障时,应满足速动性、选择性、灵敏性和可靠性的要求,其中除可靠性的要求应由保护装置本身来完成外,其它三项要求应由继电保护的整定计算来满足。随着现代电力系统的迅速发展,电网规模日益扩大,继电保护整定计算的工作量越来越大,复杂程度也越来

Abstracts
Relay setting calculation is an important part of the protection work for high voltage power system protection devices in the system failure to meet the liquid, selectivity, sensitivity and reliability req
uirements, which, interreliability requirements should be the protection device plete the other three should relay setting calculation to meet. With the rapid development of modern power system, the grid scale of the growing, and relay setting calculation workload is growing, more and plexity, so the staff structure of skilled grid protection of the subscription calculations. This article describes the role of relay protection, configuration, and the principle of detailed discussion of the principle of the relay setting calculation, the basic tasks and steps. Finally, this positive into the calculation of a 110KV grid setting calculation. The results show that this setting calculation method can be a good setting calculation on the grid.
Key words:grid: protection; setting calculation
