The Research On The Line Loss In The Distrebution Network With Distributed Generations

The distributed power generation technology is now a hot spot of research in the electric power industry.The distributed power, with its flexibility to traditional distribution network ,will be generated considerable influence.Now ,when the different distributed power access to the tradional distribution,the struction and tidal current would change largely, thus cause many new problems, the most important problem is the network loss for distribution network that has made a difference.Firstly this paper in analyzing the traditional power loss calculation method, and the distributed power of electric distribution network, on the basis of influence, introduces the basic theory of the distributed power generation technology, now widely distributed power generation technology, several of the distributed power distribution of distribution network access after the effects of damaged research. Through the establishment of a typical power network model, focus on the distributed power access distributed power distribution, the capacity, access position, and the operation mode of the distributed power of the influence of the loss, the change rule of network loss rate. Established distribution system simulation model, 33 node, according to the distributed power of access, different ways of distributed power was divided into four nodes. The back/forward by the improved flow calculation method, pushing the distributed power, analyzes on the different according to different capacity of different position, after the distribution system access the voltage influence. Get the asynchronous motors as interface distributed power will reduce system of voltage level, and use other forms interface of the distributed power system voltage have support role. The distributed power access for distribution network provide valuable reference...
