Optimized Planning And Reliability Evaluation Of Xianghe Power Grid

Distribution network lies at the end of power system, what is the last link in power supply and distribution straight aiming at the consumer in power system, possessing multi-nodes, structure complex. Programming of Distribution Network therefore more combine zone specialty and load specialty than programming of transmission network. The future demand of the electric power and the capacity of the power system are up to the forecast of the network gross load that is the basic of power system programming, which veracity right affect the advantage and disadvantage of the quality about the programming of power system, while, the voltage quality and running charge in power system lies on the programming of reactive power. We have to review the reliability index except seeing about the economic running index in the evaluation about the programming of distribution network, then make out the best choice during the diversified programming on the basic of two guidelines.This article analyzed the actuality of Xiang-he zone power system integrating the economic characteristic.Giving prominence analyzed the bright native load characteristic in time, space and trade, forecasting the metaphase and long-dated load. We have made out the future development about metaphase and long-dated power system, depending on the layout of local social economic progress. In conclusion we carried through dependability evaluation about the status quo and the programming target on the basic of the distribution network programming and reactive power programming that provided the viable referenced scheme for Xiang-he region.
