摘要
微机继电保护装置是煤矿供电系统中的重要工具。针对煤矿电力系统常见故障,提出一种基于快速傅里叶算法的新颖微机继电保护方案。该方案优化了煤矿配电网的选相判据,为煤矿继电保护发展提供了一定参考价值。利用数字信号处理器(DSP)为控制核心,独立设计部分外围电路,通过编程和运行,可实现煤矿配电网的继电保护功能。
The Microcomputer relay protection device is a significant tool in the coal mine power system. Aiming at the common faults in coal mine power system, one innovation Microcomputer relay protection scheme is proposed based on fast Fourier transformation (FFT). This scheme optimizes the phase selection criterion of coal mine distribution network and has reference value for relay protection development. This scheme takes the digital signal processor (DSP) as the control core, independent designs part of outer circuit and writes the programs. Through the programs operation, realizes the relay protection functions of coal mine distribution network.
