An Investigative Study of the PMSG Based Wind Turbine Using Real Time Simulation

This paper presents, transient and steady-state control strategy of a three-phase grid connected Permanent Magnet Synchronous Generator (PMSG) based on Wind Energy Generation System (WEGS). The converters have been interfaced with variable speed PMSG based on wind turbine and the power grid. The authors of the paper have put their significant contribution towards detecting the prior effects of the well-known faults in the operation of WEGS when connected to the power grid. When the faults occur at the grid, grid-side converter suffers because of change in inertia of the prior system due to which operation of the PMSG gets affected. It is observed that tuning of grid side converter is required due the fault occurred in the grid. Thus, it is observed that maintaining the constant DC link voltage is required for the abrupt-less operation. The simulation results of the faults such as three-phase line to line, line to ground, and realistic grid faults have been discussed in detail. This paper also reports the effectiveness of the power quality injected into the grid during the variable wind-speed turbine system. To pursue the above analysis a real time simulation tool RTDS has been used.
