摘要
结合总降压变电所的实际情况,介绍差动保护原理在我公司高压供电系统中应用的三种方式,并分别对其在各自保护范围内出现的故障进行分析。运行结果表明,该套装置能够保证供电系统安全可靠运行。
The paper recommends three ways of applying differential protection theory in high voltage power supply system of the company incorporating the practice of the general voltage decreasing substation, and analyses the fault occurred in the respective protection extent. The operation shows that the device can ensure the safe and reliable operation of the power supply system.
