Methods to improve the precision of calculation of power system line losses

Rate of power system energy losses is an important and complicated economic and technical index which reveals the level of programming,production and management of power system.So theoretical loss is usually used to guide the operation of the network.Now the calculation based on power flow is popular but there are still some deficiencies.To solve these problems,an integrated analysis is made to find out some methods to improve the precision of the result.According to that,improvements in both management and calculation are put forward.By the use of these new methods,the result of calculation is more credible.
