Research On Synthesis Power Loss Reduction Schemes For Rural Distribution Network

The power loss percentage of rural distribution network in our nation is two or three bigger than that in developed countries,which makes it valuable to reduce the power loss. The problems that cause high power loss percentage were found out through researches on rural distribution network which had been reconstructed from 1998 to 2002.The technical effect was analyzed through BPA of power loss reduction schemes towards those problems.After the calculation methord of the saved power was studied on condition that the load grows regularly,the ecomonical effect of power loss reduction schemes was evaluated with relevant techniques.The research results of representative problems instances in local rural distribution network show that only those synthesis power loss reduction schemes including two or more techniques can resolve those problems effectively if both technical and ecomonical effect was taken into consideration, however,the schemes with just one technique couldn't.
