Abstract

Aiming at the issue that zero sequence inverse time current protection of non-faulty line occurs before the protection on the side with smaller zero sequence current in the faulty line when the system with large ground current has grounding fault

a zero sequence inverse time current protection scheme introducing zero sequence current effective value and phase mutation criterion is proposed. Firstly

the distribution characteristics of zero sequence current and the operating characteristics of zero sequence inverse time current protection in the case of grounding fault in single-circuit line and double-circuit line are analyzed. It is pointed out that the zero sequence current of adjacent non-faulty lines may be greater than the zero sequence current of the faulty line

causing the misoperation of zero sequence inverse time current protection. Then

through theoretical analysis

the changes of the effective value and direction of zero sequence current in other lines before and after the protection action on the side with larger zero sequence current in the faulty line are obtained. Finally

a zero sequence inverse time current protection scheme is proposed by introducing zero sequence current effective value and phase mutation criterion

and the zero sequence inverse time current protection of non-faulty lines is re-timed. The simulation results show that the proposed scheme can effectively prevent the misoperation of zero sequence inverse time current protection of non-faulty lines

thus improving the selectivity of protection

and the proposed scheme is still suitable for transitional grounding.
