Transient Stability Enhancement using Variable Speed Wind Turbine with Direct Drive Synchronous Generators

R. Jeevajothi and D. Devaraj

Abstract—This paper investigates about the enhancement in grid transient stability while integrating the large-scale variable speed wind turbine (VSWT) with DDSG. A dynamic modeling and simulation of a grid connected VSWT with DDSG with controllable power inverter strategies suitable for the study was developed, tested and verified. This dynamic model with its control scheme can regulate real power, maintain reactive power, and generate voltage at different wind speeds. For this paper, studies were conducted on a standard IEEE 9 bus system augmented by a radially connected wind power plant (WPP) which contains 28 VSWTs with controllable power inverter strategies. Also it is proved that it has the potential to control the rotor angle deviation and increase the critical clearing time during grid disturbance with the help of controllable power inverter strategy.

Index Terms—VSWT, DDSG, rotor angle deviation and critical clearing time, transient stability, grid connected.
