Abstract
Control of a wind power plant as an isolated power source is analyzed. The plant consists of a wind
turbine (connected by means of a gear box to a three-phase synchronous electric generator) and a control
system. Mathematical models of the wind turbine and electrical generator have been proposed. The one-
step-ahead adaptive control technique has been adopted to govern the system. Results of a control test case
are shown in order to demonstrate the reliability of the proposed control technique. 1998 Elsevier Science

1. Introduction
Wind power plants are generally used to convert wind energy into electrical energy. These
plants consist of a wind turbine, an electrical generator and a control system. The wind turbine
converts wind ic energy into mechanical energy and the latter into electrical energy by means
of an electrical generator.
The flow field around a wind turbine is unsteady and three-dimensional. Mathematical models
are available in the literature for solving the equations for such plex flow. These may be
divided into momentum, vortex, and finite-difference models. The momentum models use actuator
surfaces to approximate wind-turbine effects and subdivide the flow domain into finite numbers
of stream-tubes [1–8]. Vortex models simulate the wind-turbine blades and use bounded, distrib-
uted vortices [9–17]. Finally, finite difference models solve the fluid-dynamic governing equations
by means of finite-volume or finite-difference methods [18–21].
