Composite estimation method and system for electric quantity backtracking under abnormal metering condition

Abstract

The invention discloses a combined type estimation method and system for electric quantity backtracking under the abnormal metering condition, and belongs to the field of secondary circuit metering of an electric power system. Various different types of faults are combined into one calculation method, and the calculation method is realized through mutual complementation of three modes including a table look-up method, a correction coefficient method and an estimation method. And a worker can quickly and normatively calculate the compensated electric quantity. And the modes of field actual measurement, field investigation of customer electric appliances and the like are provided, so that the electric quantity backtracking accuracy under abnormal conditions is improved. According to the method, various abnormal conditions are fused, an electric quantity compensation scene is expanded to a scene needing electric quantity backtracking, and the application range of the estimation method is effectively expanded. A good foundation is laid for later electric quantity compensation, gateway electric quantity measurement and calculation and the like through an optimized calculation mode and a larger application range, and the appeal of power supply and consumption parties for maintaining own interests is further promoted. According to the invention, the power supply party can reduce the business loss and improve the working quality and efficiency, and the safety electricity utilization consciousness of the electricity utilization party can be improved.

Description

technical field [0001] The invention belongs to the technical field of power system secondary circuit metering, and in particular relates to a compound estimation method and system for electric power backtracking under abnormal metering conditions. Background technique [0002] Electric energy metering devices are basic metering assets, and providing accurate metering is an important responsibility of power supply companies, and is an important basis for power supply companies to charge users for electricity. However, due to various human and non-human factors such as user stealing electricity, wiring errors and various irresistible factors such as failures and deviations of metering devices, over-metering, omission and wrong metering of electric energy metering devices are common. , the inaccuracy of power backtracking will have a greater impact on both the power supply and the power consumer. [0003] At present, in the case of most measurement abnormalities, the power tr...
