Abstract
The article discusses the methodology for recalculating the coefficients of ZIP load model in nodes of electric networks 35–220 kV, according to the experimental data obtained for some another network nodes. The need to recalculate the static load characteristics for nearby parts of the network arises due to problems between networks owners and the insufficient number of certified measuring equipment during the active experiment, as well as the impossibility of connecting the measuring equipment in some places of the electrical network. For recalculation, a model of an electrical network section is formed and standard models of network elements such as transformers, currentlimiting reactors and power lines are used. These models are divided into elementary multipoles and the calculation is performed sequentially for each of them. The given technique is general and allows recalculating the ZIP model coefficients of the load at an arbitrary point of the electrical network according to experimental data at some points of the network.
