This paper, based on Handan network loss calculation and loss-reducing study, analyzes sensitive factors affecting the network loss of the region power grid, proposes a series of measures to reduce energy loss on transmission line, which offers a theoretic foundation for the urban and rural power grid reconstruction in Handan.The main work of this paper includes:(1) Collecting operating data of power grid and carrying on line loss calculation of overall grid.(2) Analyzing the calculated result, finding out the exited problems and developing the functions of calculating program.(3) Proposing a series of loss-reducing measures to improve grid operating environment.(4)Demonstrating the effectiveness in practical application of the loss-reducing measures.
