Title: Differential relay system
Inventor: YAMAURA MITSURU
IPC: H02H3/28
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To obtain a differential relay system which has no possibility of making incorrect judgment even for a long distance power transmission line by adding a zero phase component of a net difference current as a restricting amount. SOLUTION: In a differential relay method judging the presence or absence of an internal fault of a three-phase power transmission line comprising a data creating section 2, a data transmitting section 3, a data receiving section 4 and a judging section 5-1, a net difference current Jd is calculated in the judging section 5-1, and further an amount Jdo corresponding to 3 times the zero phase portion of the net difference current Jd is calculated. Next, a ratio restricting amount K (|JAp |+|JBp |) of a judging equation and the restricting amount G|Jdo | by the zero phase portion of the net differential current is added in addition to a constant restricting amount Ik . Then, if this judging equation is found to be valid, a circuit breaker of power transmission line is tripped by an output OP.  By doing this, even though an error occurs at a sound phase with a zero phase current by an internal fault of other phase, error judgment can be prevented by the restricting amount g|Jd0 |.
