摘要
根据多端线路电流差动保护的要求，提出了一种基于ＧＰＳ的新型数字式分相电流差动保护硬件方 案，同时还提出了较为完善的抗干扰措施。通过引入ＧＰＳ定时技术解决了远距离多端同步采样问题，从而使 电流纵差保护具有更高的可靠性。
A GPS -based new digital phase -split current differential protection hardware scheme is suggested together with better anti -interference measures to provide current differential protection for multi -terminal circuits. GPS timing technique is used to realize remote multi -terminal synchronized sampling thereby enhancing the reliability of longitudinal difference protection of current.
