11型微机线路保护原理缺陷浅析与应用对策

Principle flaws analysis and application countermeasures of 11 type microprocessor-based line protection

11型微机线路保护是我国自行研制的第一代产品的典型,在全国高压网络中应用较早且数量很大。它的出现使继电保护装置的构成和实现方式产生质的飞跃,使我国的线路保护一举跃入单片机时代。结合运行中的实际问题定性分析、探讨该保护软件可完善的方面及应用注意事项,供运行及科研的同行参考。

The 11 type microprocessor-based line protection, which is the typical model of first-born products made in China, is early used with a large amount in nation-wide high-voltage networks. Its popularization makes the structure and realization of relay protection optimized fundamentally, which makes our line protection step into the period of single-chipprocessor.Based on the practical problems of its operation, this paper tries to analyse and research perfectable and applicable aspects qualitatively, so as to give a reference for people who work at the field of operation and scientific research.
