This paper presents low voltage ride through (LVRT) characteristics analysis of variable speed wind turbine (VSWT) driving a permanent magnet synchronous generator (PMSG). The VSWT-PMSG is becoming very popular these days in wind power application. In some recent studies, the transient stability and LVRT characteristic of VSWT-PMSG has been reported using different types of symmetrical and unsymmetrical...
The increasing penetration level of wind farms in power system network requires better understanding of short-term voltage stability and ride through capability before their interconnection to grid. The future wind turbines must stay connected irrespective of any type of disturbance in grid. To achieve reliable operation and control, the wind turbines must be actively controlled in order to meet the...
A novel control strategy for the operation of a permanent magnet synchronous generator (PMSG) based stand alone variable speed wind turbine is presented in this paper. The direct drive PMSG is connected to the load through a switch mode rectifier and a vector controlled pulse width modulated (PWM) IGBT-inverter. The generator side switch mode rectifier is controlled to achieve maximum power from the...
