摘要
在分析电网漏电故障规律的基础上,设计了一种适于不同中性点接地方式的电网的新型智能化综合保护系统。本文重点分析保护系统的原理,并介绍了硬件结构和软件框图。该保护系统经试验运行性能稳定,运行可靠,具有推广价值。
On the basis of analyzing the leakage fault laws of distribution network, a new intelligent comprehensive protective system suitable for the network with various neutral-point wiring modes is designed. The principles of protective system are emphatically analyzed and the hardware structure and software block diagrams are introduced. The trial running shows that the protective system is stable in performance and reliable in operation and will be of great popularization values.
