Analysis and Prospect of Power Supply Reliability in China in 2017

By depth mining, the data index of power supply reliability is analyzed, the hidden common problems and important information are found out from the large-scale reliability data, the weak links of the planning of distribution network and transportation inspection are found, and the effective measures are put forward to promote the improvement and promotion of the reliability management of the power enterprises. Measures to improve professional management are of great significance for improving the reliability of distribution network power supply. This paper summarizes and analyzes the national reliability data indicators of 2017. From the perspectives of users' blackout frequency, power outage time, power outage range and blackout causes, the overall level of national power supply reliability and the trend of change are analyzed. What's more, the current problems and challenges in reliability management are summarized, and the future development is prospected.
