First Time

The Wind Energy Group has designed and manufactured a 20 m diameter wind turbine generator, rated at 250 kW. Following an extensive period of tests, it was erected on Orkney in July 1983. It rotated for the first time in late July and was synchronized with the grid in August 1983. The commissioning tests have been completed and are to be followed by not less than twelve months of performance monitoring. This paper gives details of the machine design and specification, details of sensors and monitoring system and early results of the commissioning phase. As part of the same programme, a 60 m diameter turbine rated at 3 MW has been designed for installation in 1985 at the same location. Details are given in this paper of the design and specification of this machine.

Control Scheme

The variable speed wind turbine generator exhibits serious nonlinearity, uncertainty and difficulty accurate modeling, conventional PID controller can't achieve ideal control effect. In this paper, an adaptive inverse control scheme based on neural network identification technology is proposed to solve the above problem. The scheme firstly uses online identification of one DRNN to obtain the Jacobian information of plant. On this basis, another DRNN identifies the inverse plant model which constitutes adaptive inverse control system as controller. The simulation results verify that the adaptive inverse control scheme has excellent adaptability and robustness, which can make the actual rotational speed of wind turbine rapidly track the set point to maintain the best tip-speed ratio in order to get maximum wind energy capture in the random wind conditions.

Ac Transmission

Due to the continuous resources’ reduction and cost increase of conventional fossil fuel along with the global trend to decrease the greenhouse effect, clean energy production from renewable sources has been given a global great concern. Among renewable energy sources, wind energy conversion systems have received a worldwide notable attention. It is expected that more than 10% of the global electricity demand will to be generated by wind energy conversion systems by the year 2020. During their early implementation stage, wind turbines were to be disconnected during abnormal and fault conditions within the electricity grid it is connected to. Owing to the fact that current wind installations supply a significant portion of the load demand, disconnecting windfarms may lead to business interruption and discontinuity of power supply to the end user. As such, transmission line operators have developed strict grid codes that wind turbine generator must meet to maintain its connection to support the grid during various fault conditions. To comply with these codes, flexible AC transmission systems have been widely used with current wind energy conversion systems to modulate reactive and/or active power at the point of common coupling of the wind turbine generator and the grid. This book presents the applications of various flexible ac transmission system devices to wind energy conversion systems. Devices such as unified power flow controllers, superconducting magnetic energy storage and static synchronous compensator are covered in this book. Topologies, control systems along with case studies of the aforementioned devices are presented and discussed. This book will be useful for postgraduate research students, upper-division electrical engineering students and practicing engineers.
