A real-time loss calculation for 10 kV distribution based on three-phase distribution monitored data

According to the practical situation of distribution automation system and some characteristics of distribution network, a new loss calculation method for 10kV distribution network is presented by making use of the three phase distribution monitored data. This new method divides feeder line into feeder sections based on the variable structure dissipated network theory, then models every facility in these feeder sections. Combined with real time monitored data, not only the calculation accuracy is improved, but also the detailed losses of feeder sections can be obtained, therefore, the loss distributing of distribution system can be required clearly.Consequently, the method can help personnel carry through distribution loss analysis and calculation simply and can give powerful reference in optimizing distribution system further.
