摘　　要：云南省电解铝用电负荷占比逐年攀升,建立具有工程实际价值的电解铝负荷模型及参数对开展大电网仿真工作起着举足轻重的作用。首先,基于电解铝的动态模型和生产实际条件建立其实用负荷模型。其次,考虑实用模型有功、无功参数的耦合性,采用双目标辨识方法分别确定用于频率、电压稳定分析的模型参数。最后,针对辨识过程中产生的参数一致性问题,提出了基于多曲线拟合的单点化、统一化辨识方案,并结合实测数据验证方法的可行性。The proportion of electrolytic aluminum load in Yunnan province is increasing year by year.The establishment of electrolytic aluminum load model and parameters with practical engineering value plays an important role in the simulation of large power grid.Firstly,a practical load model is established based on the dynamic model and actual production conditions of electrolytic aluminum.Secondly,considering the coupling of the active power and reactive power parameters of the practical model,the model parameters for frequency and voltage stability analysis are determined by the dual-objective identification method.Finally,aiming at the problem of parameter consistency in the identification process,a partition and unified identification scheme based on multi-curve fitting was proposed,and the feasibility of the method was verified with the measured data.
