摘要
Abstract
Grid closed-loop running or electromagnetic loop network operation can improve power supply reliability and economy, while it makes relay protection setting calculation complicated at the same time. According to the Pingtan island grid multi-loop operation, put forward a scheme of relay protection setting calculation. The problems and measures of the power grid are analyzed, such as operation mode selection, setting principle, setting order, protection coordination endless loop, protection or switch failure, reclosing ,etc. The scheme can improve the ability of line protection to adapt to various operation mode, reduces the workload of modifying fixed value or switching fixed value area. Safe and stable operation of the Pingtan island power grid shows the rationality and feasibility of setting scheme.关键词
