The Theoretical Line Loss Analysis Of Dandong Power Grid And Management Research

The line loss is an important technical and economic indicators of the nationalassessment of the power grid companies, also it’s the comprehensive reflection of powergrid enterprise management level of the comprehensive embodiment, Line LossManagement is an important part to reduce operating costs, increase enterprise efficiency.Do line loss calculation with the distribution network can be found the weak links in thedistribution network, learn the composition of the wear and tear, targeted to takereasonable measures to loss reduction, reduce the network losses, have very importantsignificance to improve power economic efficiency of enterprises.Based on the theoretical calculation of line losses research significance and typicaltheoretical line loss algorithm are introduced, on the basis of this discussion of reactivepower compensation, power grid structure, load distribution, distribution transformercapacity-load ratio and unbalance on the influence of line caustic, and a detailedcomparative analysis. The paper has built a line loss analysis system based on multi-agenttechnology, con ducted in-depth analysis of system structure and the main function ofagent.Combining with the regional power grid of Dandong, full of theoretical line losscalculation, and the results were pooled analysis. Through to the Dandong various voltagelevels exist problems deeply, for the Dandong area power network loss modification andpower grid planning has provided the very good reference.For the realization of loss reduction on the low pressure area management, a portableassessment metering device is designed. The device has combined the open currenttransformer and the power meter rationally, narrowed the scope of the investigation for thehigh loss district, delineated of the loss region, locked key customers, detected high-losspoint accurately, targeted to carry out an electrical check and can effectively reduce theloss of the low pressure area management. The equipment is simple produced, easy tooperate and has a good prospect of application.
