In China,most of distribution system is neutral noneffectively grounded. And the single-phase fault often happens through cement pole. In this paper,firstly,the voltage of the fault phase and the current of cement pole are derived in 10kV neutral noneffectively grounded distribution systems when cement pole has single-phase ground fault.Secondly,the online fault location method is proposed based on voltage gradient of cement pole.Thirdly,the resistence characristic of cement pole is analyzed and the distance obtained from the gradient voltage of cement pole is given.Finally, the theoretical analysis and simulation experiments show that the method is feasible.

Based on the analysis of the transient process of the electric line’s developing ground fault, this paper applies the oppositely-directed travelling wave fault location method to fault location in distribution network. Simultaneously, this paper chooses proper wavelet generating functions to find the modulus maximum of oppositely-directed travelling waves and summarizes the methods and steps of this oppositely-directed travelling wave fault location. Finally, PSCAD/EMTDC is used to simulate the single-phase ground fault to verify the oppositely-directed travelling wave fault location method.

Due to the high ground fault resistance and the complexity of power distribution network structure (such as too many nodes, branches and too long lines), adopting common traveling wave method and ac injection method can not effectively locate the single-phase grounding fault in the distribution network system.To solve above problems and determine the position of the point of failure prisely, this paper adopted the dc location method of injecting the dc signal from the point of failure under the power outage offline. This paper introduces the single phase dc method and the method of three phase dc, and the simulation shows that the dc location method is effective and feasible.
