Abstract

The invention provides a line loss calculation method based on multi-source data fusion, and the method comprises the following steps: 1) information synchronization: collecting data information comprising a power grid account, topological information and operation data, converting and storing the data information in a database, and obtaining multi-source data; 2) multi-source data fusion: performing data processing and data fusion on the obtained multi-source data to obtain power grid line loss related characteristic data; 3) power grid line loss calculation; and 4) element loss calculating.According to the method, the calculation process of information synchronization, data fusion, feature extraction and line loss calculation is realized, the electric energy loss of various elements ofthe power grid is accurately obtained, and the energy-saving and loss-reducing effects of power distribution network frame optimization, compensation equipment selection and matching, distribution transformer economic operation and the like are accurately evaluated and verified.

Description

technical field [0001] The invention belongs to the field of electric power, in particular to a line loss calculation method based on multi-source data fusion. Background technique [0002] The lean management of the distribution network is a complex and huge project of reform and innovation under the requirements of the two main lines of the smart grid. The promotion of lean distribution network has changed the unfavorable conditions such as difficulty in data collection and unknown power supply range, provided a data source for large-scale and in-depth subdivision theoretical calculations, improved the real-time and accuracy of theoretical line loss calculations, and provided a basis for line loss calculations. Condition monitoring and line loss lean analysis and management create conditions, and also provide a basis for the formulation of line loss assessment indicators and performance evaluation. Through the comparison and diagnosis of theoretical line loss and statisti...
