Distributed connected-grid generator becomes an important approach to utilize renewable energy. However, traditional distributed connected-grid inverter can't be controlled and still can not be accepted by Power Grid Company. On the basis of conventional connected-grid inverter, a novel connected-grid inverter controlled by center controller was designed, which gets separate dq current component by...
In this article, we present a novel gang control system in drive application for a six-phase induction motor, forcing on the properties of gang Variable Voltage Variable Frequency(VVVF) control system, which is based on integration of power drive modules and power electronic system. The design of VVVF system for six-phase induction motor is set up, the results of theoretical analysis and MATLAB simulation...
A novel PV power inverter applied in micro-grid is developed in this paper. It runs not only in connected-grid but also in disconnected-grid and keeps voltage stable rapidly in transient process. When the inverter is connected with the grid, the inverter produces power as a current-source with voltage-current close loop control strategy. Once the islanding event takes place, it runs as a voltage-source,...
In order to keep a parallel inverter system operating stably, it is important to restrain the circulating current effectively. Based on the theoretical analysis, the limitation of a conventional conclusion about ideal operation status of parallel inverters is studied in detail. And then, the ideal operation status of the parallel inverter system is well investigated in this paper. A new criterion...
This paper focuses on ideal operation status of the parallel inverter system. The limitation of conventional conclusion about ideal operation status of parallel inverters is discovered. And a new conclusion is introduced, that there will be no circulating current among parallel inverters when their unattached output voltages have the same frequency, phase, amplitude and be uniformly modulated. Simulation...
