摘要
对当前矿井供电系统与漏电保护系统进行分析,并基于MATLAB对电力系统进行仿真,提出以零序暂态能量法和零序功率法相结合的漏电保护综合选线方法,在以16位单片机MC9S12XS128MAA为控制核心的漏电保护器上搭建试验测试平台。结果表明,漏电保护综合选线方法有效改善了选线的准确性和适应性。
The current mine power supply system and leakage protection system are analyzed, and on the basis of MATLAB simulation of power system, a zero-sequence transient energy method and zero sequence power method combined single-chip MC9S12XS128MAA for with leakage protection integrated control of the core of the leakage line selection method, in 16 protection on the test set up a test platform. It is proved that the integrated route selection method of leakage protection effectively improves the accuracy and adaptability of the selection line.
