由两台发电机组成的独立电力系统数学模型

摘要

针对由两台发电机组成的独立电力系统过渡过程数学模型问题,基于同步电机相坐标系数学模型推导出了由两台发电机组成的独立电力系统数学模型,并给出了其初始条件的确定方法.应用该模型不仅可以研究同时存在一种或几种扰动时的过渡过程,还可以进行对称和不对称工作状态的计算.对于工作于有限功率电力系统或独立供电电力系统中重要同步电机过渡过程的实际计算来讲,该模型应用广泛.%An independent power system mathematical model composed by double generators based on synchronous generator phase reference frame was established to solve the asymmetry in the calculation model of short-circuit current of generator in independent power system as well as confirmation of the initial condition. Not only can the transition of one or more scrambling be studied, but the calculation can be conducted in both symmetrical or asymmetrical status. To the transition calculation of crucial synchronous generators in finite power system or independent power system, this method put forward is bound to be used widely.
