摘要
重点分析了分布式电源并网和高压直流输电对继电保护的影响以及智能电网对保护的要求,从而得出以下结论:智能电网背景下要求继电保护有更快的反应速度,更好的协调能力和更强的适应能力。
This paper focused on the influence of distributed generation connection and HVDC transmission to relay protection, and on the requirement of smart grid to relay protection. The conclusion was that smart power grid required faster reaction speed, better coordi- nation ability and better adaptive capacity to relay protection.
