Research on Fault Diagnosis Platform of Distribution Network Based on Multi-source Data Fusion

In recent years, the industries are developing rapidly in China, the supply side electricity consumption is increasing, the quality of electricity requirements are also improving. 10kV distribution network is an important hub connecting users with 66kV main network. The stability of distribution network can effectively guarantee the operation efficiency and power supply quality of the whole power system. Because the distribution network is widely distributed and the distribution equipment is scattered, the failure of the distribution network is easy to affect the power supply of residents, and even lead to the failure of the power system. Therefore, the failure of the 10kV distribution network is investigated and judged quickly, so as to carry out the repairing emergency command work in time and ensure the normal operation of the power system. It will be scattered in different areas, data source convergence in distribution network system platform and unified analysis, multi-source data integration technology is used and grid public information model of distribution network is based on data comprehensive. It will be rapid integration, deepen the distribution network fault analyzes technology, this technology can increase the rate of 10kV distribution network fault repairing and shorten the time to restore power, effectively improving the accuracy of the distribution network fault diagnosis.
