【摘要】 为研究考虑微型燃气轮机(MT)的配电网综合负荷建模,在构建适合分布式电源的MT发电系统的基础上,详细阐述了各功能模块的模型和控制策略;通过对暂态过程中MT发电系统的动态运行特性分析,可以将MT看做是一个功率消耗为负的广义动态负荷,进而提出一种以永磁同步发电机转子角速度为状态变量的一阶微分状态方程模型来等效描述MT发电系统的动态特性;通过对不同程度扰动下的仿真建模比较分析,验证了该等效描述模型的有效性。更多还原

【Abstract】 In order to study the composite load modeling of distribution network with microturbine (MT),the MT system is established and the models of each function module and control strategy are expounded. Through the analysis of the dynamic performance of a MT power generation system in transient,the MT could be considered as a generalized dynamic load which consumes negative power. Based on this,the first-order differential state equation is proposed to describe the dynamic characteristics of the MT system. This description model is based on rotor angular velocity of permanent magnet synchronous generator (PMSG) as state variable. The validity of this equivalent description model is validated by comparison of simulations with different disturbance levels.更多还原
