Abstract

The positive-sequence fault components (PSFC) in the distribution network are analyzed and an inverse-time current differential protection scheme using the PSFC is discussed.According to the current responses of distributed generations (DGs) during fault,positive-sequence fault component complex network of short circuit fault is established.Secondly,the PSFC currents of two monitoring points of protection section are inferred rigorously.And the amplitude and phase characteristics of the PSFC current distribution are invested qualitatively.Combining with the configuration and parameters of the distribution networks,the inverse-time differential protection criterion and setting principle are proposed.Finally,simulations modeled by PSCAD are used to verify the effectiveness of the proposed protection criterion.Simulation results demonstrate that:(1) the scheme presented in this paper can distinguish motor self-starting and slight fault efficiently.(2) it can also solve the contradiction between enough ability for braking saturation current of the current transformer and improving sensitivity to internal faults.(3) it can adapt to multiple situations,e.g.output randomness of DG,variety configuration of feeders.

Key words： Active distribution network inverter-interfaced distributed generations unmonitored branch current differential protection inverse-time
