[0110] figure 1 It is based on the accurate algorithm of the three-phase full cycle integral loss of the electricity consumption information acquisition system to introduce the background diagram, as shown in the figure, the present invention evaluates the root mean square current method, the average current method, and the maximum current method, taking into account the load fluctuation of the distribution network The characteristics of strong, three-phase imbalance and distortion, the three elements of line loss analysis (model algorithm, line parameters, and collected data) within the range of medium-voltage distribution lines, distribution transformers, and low-voltage stations are studied to obtain the three-phase full cycle Accurate calculation of integral loss.
[0111] figure 2 The topological structure diagram of the medium-voltage distribution network is analyzed according to the example of the method of the present invention. This diagram is a typical medium and low-v...
