摘要
论述了利用光纤通讯技术及计算机技术实现数字式分相电流差动保护的方案，比较了数字式分相电流差动保护与传统导引线保护、相位比较保护的优点，指出该保护尤其适用于城网改造的短线路．
This paper describes the scheme of digital phase-splitting current differential protection which is realized using fibre-optical and computer technology,compares the advantages of the digital phase-splitting current differential protection with conventional pilot protection and phase comparison protection,and points out that the protection is especially available for short lines in power network improvement.
