摘　　要：为了研究含微型燃气轮机发电(microturbine generation,MTG)的配电网综合负荷模型,建立了适合用于分布式发电仿真的MTG数学模型,提出了MTG三阶微分状态方程的等效描述模型,通过建模仿真验证了模型的有效性.在此基础上,提出了含MTG的配电网广义综合负荷模型结构——MTG等效描述模型并联传统综合负荷模型.在3种不同负荷水平、不同扰动程度条件下对该广义综合负荷模型的有效性进行了检验,验证结果表明,本文所提出的广义综合负荷模型具有较好的自描述能力、泛化能力和参数稳定性.In order to study the composite load modeling of distribution network with microturbine generation（MTG） system,the grid-connected MTG system was established.The third-order differential equation of state description equivalent model of MTG system was presented,and the validity of this equivalent description model was verified.Based on these,the model structure of the generalized load model of distribution network with MTG system could be described as traditional synthesis load model paralleled with MTG equivalent description model.The model validation was testified by the simulation modeling of different disturbance levels and different load levels,The verification has indicated that the generalized synthesis load model proposed has good description ability,generalization ability and parametric stability.
