摘要
比较了美国SEL-321-5微机线路保护与国产微机线路保护之间的差异，深入分析了SEL微机保护的高频及振荡逻辑，就如何整定SEL微机保护和运用及编制其逻辑方程进行了较详细的论述。
The difference of numerical line protective relay SEL and domestic protection relays is compared in this paper.Then the high-frequency logic and oscillation logic of numerical line protective relay SEL are thoroughly analyzed. How to set protective relay SEL and how to program the SELOGIC control equation are discussed in detail.
