Large Grid-connected Wind Farm To The System Influence Analysis And Its Application Studies

The pressure that the electric power demanding increment and environmental protection request promoted the development of the new energy. The wind energy was developing fastest among all kinds of renewable resources due to its a kind of renewable green power resources, its low cost and technical maturity. With the development of wind industry, there would be more wind farm of 100MW,this kind of large wind farm would bring many problems to the power system' operating. moreover, the intermittence and fluctuating of wind farm power output would produce the certain influence to voltage quality of the power system, result in voltage level fall of local network and become serious obstacle of the further utilization of the wind resource. Therefore research on characteristics of grid-connected wind farm became an important issue to the design and operation of the power system.The major research and contributions were as follows:...
