继电保护装置在保证电气化铁路牵引供电系统的可靠运行方面发挥着重要作用。针对牵引馈线短路瞬间电流波形发生畸变的“形态”特征,用偏度与峰度进行定量描述,提出牵引网暂态保护新方法。用牵引变电所故障录波数据进行检验,获得令人满意的判断结果。
Relay protection devices play an important role in ensuring the reliable operation of the electrified railway traction power supply system. A new method of transient protection for traction network was proposed based on the “” morphological "distortion of the current waveform of the traction feeder at moment of short circuit. The skewness and kurtosis were quantitatively described. Traction substation fault oscillographic data test to obtain satisfactory results.
