The Model of Distributed Grid-Connected Dc micro network Inverters and Double loop Control Method

摘要：

　　In this paper,for parallel operation of the three-phase PWM inverter control system,we put forward and set up the equivalent grid inverter mathematical model.In the process of grid inverter equivalent model is discussed,for the three-phase inverter system is a nonlinear system,in order to facilitate the performance of the system analysis and design of the control system,the transfer function of the system were analyzed to the linearized system.After the linearization control the theory system can be discussed using the method of classical.On the premise of system average model we get the static working point system,according to the law of small signal,we can obtain the small signal mathematical model.At the same time,discusses the three phase inverter design of double loop control system.
