The present invention provides a method for synchronous calculation and multidimensional analysis of distribution network line loss, which includes the following specific steps. Step 1. Install high-voltage metering devices on each branch, segment and contact node of a 10kV distribution network line, and perform the calculation through a wireless public data network. Networking; Step 2. The high-voltage metering device of each line node collects data synchronously to the remote background system in real time; Step 3. Collected data information of each line node; Step 4. Combined with the power meter data of the power consumption information collection system Data from substation outlet meters in the dispatching automation system; statistical calculation of daily line loss and monthly line loss, and correlation analysis; Step 5. Find out the section of the line whose line loss rate exceeds the standard, so as to locate it; Step 6. Assist Decision-making to help power companies find out the cause of line loss problems. The invention is used to solve the problems of lack of line data, out-of-phase line loss data, lack of abnormal line loss location and line loss cause discrimination in the current distribution network line loss calculation.
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...
