一种光学电流互感器应用于多端差动保护的方法
摘要：
本发明属于继电保护领域，是将光学电流互感器应用于多端差动保护的一种新的方法。解决了新型光学电流互感器应用于多端差动保护中如何进行差动保护计算的问题。利用法拉第磁光效应原理的光学电流互感器可以完全保真的反应一次测电流的全波形，从而可以进行全波性电流多端差动保护计算。通过这种新型差动保护计算可以提高差动保护的速动性和可靠性。
摘要（英）：

The invention belongs to the relay protection field, provides a novel method of applying an optical current transformer to multiterminal differential protection, and solves the problem about how to conduct differential protection calculation by applying a novel optical current transformer to multiterminal differential protection. The optical current transformer employing the Faraday magneto-optical effect principle can reflect full waveforms of currents of a primary side in a complete fidelity manner, so full waveform current multiterminal differential protection calculation can be performed. Through the novel differential protection calculation, the differential protection speed and reliability can be improved.
