Analysis of Technical Losses in Hubei Power Grid

The power system loss is a very important technical and economic indicator in power enterprises. In a system, there are two types of losses: technical losses and non-technical losses (commercial losses). Out of the total system losses, technical losses can be reduced more directly and effectively. This paper focuses on the analysis of the variation and contributing factors of technical losses of each voltage class in Hubei power grid. As a result, main reasons and solutions for reducing technical losses are figured that provide a better understanding of weakness and loss composition of Hubei power grid, and are useful for power enterprises that intend to reduce electric losses as a benchmark and as a background in the planning purposes.
