Single-phase ground fault is the main type of faults in the distribution network, exerting a significant impact on the safe and stable operation of the power system. Single-phase ground fault boundary complexity, randomness, a variety of factors, to explore the changes in electric energy information of single-phase ground fault in distribution network is crucial. This paper established a single-phase ground fault model of 10 kV distribution network through simulation, and explored the influence of four conditions, namely, grounding resistance, fault phase, line length and load current, on the information of single-phase ground fault electric energy. The results show that grounding resistance, line length and load current are important factors affecting electric energy, and fault phase has little influence on electric energy information. The power at the head of the bus and faulted line decreases with the increase of grounding resistance, the power value of each line decreases with the increase of line length, and the faulted line power increases with the increase of load current.
