摘要
提出了考虑特殊负荷的实际电网电力负荷综合建模方法。对典型日负荷曲线进行分析,定义了特殊负荷与一般负荷的分类判据;根据特殊负荷生产特性,采用适用于电解铝类负荷的I+M型综合负荷模型和适用于铁合金类负荷的Z+M型综合负荷模型;最后根据分类结果和典型负荷节点的参数辨识,建立宁夏电网负荷模型。仿真结果和实际调研结果对比表明,该方法效果良好,建立的模型更接近宁夏电网实际负荷特性。
An approach of load modeling is proposed for the power grid with special loads. The typical daily load curves are analyzed and a criterion is defined to classify the special loads and general loads. The production characteristics of special loads are analyzed and the special load models are applied：the SLM（Synthesis Load Model） of I＋M for the primary aluminum load and the SLM of Z＋M for the steel mill load. The load models are developed for Ningxia Grid by load classification and node parameter identification. The comparison between simulated and recorded curves indicates that the load models developed with the proposed method reflect the real load characteristics of Ningxia Grid.
