应用模型拼接建立的全电网模型

为提高电网分析的准确性,调度中心采用的电网模型应从外网等值模型逐步过渡到全电网模型。通过BPA(bonneville power administration)电网模型与能量管理系统电网模型进行模型拼接可生成全电网模型,分析了模型拼接的难点、步骤。算例结果表明应用全电网模型进行电网分析可提高计算精度。

Creation of Complete Power Network Model by Splicing Power Network Model for EMS With External Network Model Built by BPA

To improve the accuracy of power network analysis,the network model currently applied in dispatching center,in which the external power network is expressed as equivalent model,should be graded into complete power network model.By means of splicing power network model for EMS with external network model built by BPA,a complete power network model can be created,and the difficult points of model splice and the procedures for it are analyzed.Case study results show that by use of complete power network model,...
