The invention provides a distribution network line loss synchronization computation and multidimensional analysis method. The method comprises the following specific steps: 1, high-voltage metering devices are installed on each branch, a segment and a contact node of a10kV distribution network line respectively, and networking is carried out through a wireless public data network; 2, the high-voltage metering device on each line node acquires and synchronizes data to a remote background system in real time; 3, the data information of each line node is acquired; 4, in combination of region electric meter data of a power information acquisition system and substation outlet electric meter data in a dispatching automation system, statistical calculation of daily line loss and monthly line lossis carried out, and correlation analysis is carried out; 5, a line segment with a segment line loss rate exceeding a standard can be found out and is positioned; and 6, aided decision making is carried out, and a power company is assisted to find out the causes of the line loss. The problems that the current distribution network line loss calculation lacks line data, the line loss data are not synchronized, abnormal line loss positioning and line loss cause judgment are lacked and the like can be solved.
Description
technical field [0001] The invention relates to the field of line loss calculation of a 10kV distribution network, in particular to a synchronization calculation and multidimensional analysis method for line loss of a distribution network. Background technique [0002] With the reform of the national power system, power companies have transformed from the main body of electricity sales to the main body of power transmission and distribution, and the source of sales profits has also changed from the price difference between buying and selling electricity to "tolls" for power transmission and distribution. Therefore, the line loss in the process of power transmission and distribution will have a greater impact on the production and operation profits of power companies. In this regard, due to factors such as complex grid structure, poor line maintenance, and many types of low-voltage loads connected to the 10kV distribution network, its line loss accounts for the main body of t...
