Abstract

The invention provides a rural load type load modeling method based on load curve decomposition. The method includes the following steps of decomposing a rural load curve, and calculating the proportion of each type of loads in all rural loads; calculating static load equivalent parameters, dynamic load equivalent parameters and power distribution network system impedance, combining the parameters and the impedance with power supply area network topology data of rural load nodes, and obtaining a rural load type load model. According to the rural load type load modeling method based on load curve decomposition, the defects of a traditional statistics and synthesis method are overcome, modeling can be rapidly, conveniently and accurately conducted on rural load stations, accuracy of power grid simulation calculation can be improved due to the load model produced through the method, and safe, reliable and economical running of a power grid is ensured.

Description

technical field

[0001] The invention relates to a modeling method, in particular to a load modeling method based on load curve decomposition in rural areas. Background technique

[0002] Power system digital simulation has become the main tool for power system planning and design, dispatching operation and analysis research. The mathematical model of each component of the power system and the mathematical model of the whole system constituted by it are the basis of power system digital simulation. The accuracy of the model is directly related to Influence simulation results and decision-making schemes based on them. The model and parameters used in the simulation are important determinants of the accuracy of the simulation. At present, the detailed mathematical models and modeling techniques of generators, excitation systems, speed control systems, transformers, and transmission lines have been well developed. The electric load model is still relatively simple, and it is of...
