漏电防火报警系统中连续过载电流调度算法的实现

漏电防火报警系统又称剩余电流报警系统，通过探测线路中漏电流的大小来判断火灾的发生的可能性，从而能够提早预防火灾发生，起到与现有消防系统相互补充的重要作用。针对供电系统实际情况，提出基于比例因子的连续过载电流调度算法，考虑到过载长延时，过载短延时以及短路情况的不同，进一步改进控制算法，使得这种控制算法比较适合在该系统中推广。经过现场试验和时间验证，这种对多规格延时的过载电流的调度算法能够反映实际现场情况，较为满意地实现过载电流的控制。

Implementation of Continuous Overload Current Scheduling Algorithm in Fire and Leakage Alarm System

The leakage current fire alarm system also known as surplus alarm system,which detects the leakage current of the circuit to determine the possibility of fire,prevents the fire hazard,plays an important complementary role for the existing fire protection system.The continuous overload current scheduling algorithm based on scale factor is proposed according to the actual situation in power supply system.After field testing and time-tested,this specification of multi-delay overload current scheduling algorith...
