摘要
针对四川电网的特点对传统的时变自适应综合负荷模型进行动态有功和无功补偿改进,设计了适用于四川电网的负荷建模与预测辨识软件。软件仿真结果表明改进的负荷模型能获得具有更高精度的辨识参数,有效提高了电网分析的鲁棒性。本软件具有数据处理、模型选择、参数辨识、历史数据保存等多种功能,该软件的应用能够有效提高四川电网的分析水平。
In the light of Sichuan power grid features, the traditional time-varying adaptive composite load model is compensated by using the dynamic power compensation process, modeling and forecasting recognition software is designed for Sichuan power grid. The designed software has the functions on the data processing, model building, parameter identification, historical data and so on. The software simulation results show that the robustness characteristic in the load model can be effectively improved, and the parameter estimation result has higher accuracy by using the improved model. The application of this software can effectively improve the analytic level of Sichuan power grid.
