“…This difficulty is overcome by noting a very interesting feature of the expression for Pe and Qe of the induction generator. We note that the expression for Pe (10) and Qe (13) can be recast as a quadratic function of a new variable R 2 /s. Hence, even when R 2 and s are unknown the quantity R 2 /s (say R eq ) can be computed by solving the quadratic equation in R eq involving Pe.…”

Transient stability of DFIG wind turbines at an external short‐circuit fault

2005

The fast development of wind power generation brings new requirements for wind turbine integration into the network. After clearance of an external short-circuit fault, gridconnected wind turbines should restore their normal operation without power loss caused by disconnections.This article concentrates on the transient stability of variable speed wind turbines with doubly fed induction generators (DFIGs) at an external short-circuit fault. A simulation model of a MW-level variable speed wind turbine with a DFIG developed in PSCAD/EMTDC is presented and the control and protection schemes are described in detail. The transient process of grid-connected wind turbines with DFIGs at an external shortcircuit fault is analysed, and in critical post-fault situations a measure is proposed for the voltage recovery of DFIG wind turbines after fault clearance. Simulation results demonstrate that in uncritical post-fault situations the control schemes are able to restore the wind turbine's normal operation without disconnections.It is also proved that the proposed measure is effective in re-establishing the voltage at the wind turbine terminal in critical post-fault situations.

This paper shows a model of a doubly fed induction generator (DFIG) including a simplified model of a wind turbine for the purpose of transient stability analysis of large-scale power systems with great wind farms penetration. The wind turbine model and the DFIG model are systematically deducted in this paper.Specially,the improved model of rotor-side converter and the simplified grid-side converter model are considered in our work.The corresponding machine-network interface solution based on the synchronously rotating common x-y reference frame is elaborately issued in this paper. Furthermore, a method is proposed to calculate the DFIG initial conditions as well. A simplified model of the turbine is used excluding among other components the pitch control.Recently, renewable energy sources especially like wind energy are gaining significant interest throughout the world. Since the first wind turbine for electricity generation was developed, the corresponding technology has been widely improved step by step. [1][2][3][4] By the end of the 1990s, wind energy has re-emerged as one of the most important sustainable energy resources. It is known that the wind power is increasingly considered not only a means to reduce the CO 2 /NO x /SO 2 emissions generated by traditional fossil fuel-fired utilities, but also a promising economic alternative in areas with appropriate wind speeds. 5 Wind power is expected to play a comparatively significant role in the future national energy scene. As increasing of penetration levels of wind power, the assessment of the effects of the wind power penetration to an existing interconnected large-scale power system becomes very important and imperative. In the technical point of view, power system engineers have to confront challenge regarding the network integration of wind power, especially with the consideration of transient stability analysis. A great amount of literature have been published in investigating the dynamic behaviour of wind generator system in recent years. Malatestas et al. 6 and Stavrakakis and Kariniotakis 7 investi-
