摘要
光纤电流差动保护是高压线路主保护的发展趋势。文章阐述了光纤分相电流差动保护的基本原理,高压线路保护装置配置相同原理差动保护的不同动作特性,以及通过不同原理的差动保护来解决其速动性和灵敏性。
optical-fiber differential protection is the developing tendency of high voltage main protection. The paper discusses basic principle of dispersed phase current differential protection, high voltage transmission line protection device configures different protection action of the same principle differential protection and different principle of differential protection to solve quick-action and sensitivity of the protection.
