POWER CONTROL OF A WIND PARK

摘要

The invention relates to a method for controlling a wind power plant (1) or a wind park. A power control module (55) for the power output into a power grid is, according to the method, supplemented with an additional power device (6). This additional power device is operated in such a manner that, according to the voltage in the grid (9), a current reserve is established and is applied in the form of a correction value to the power control module (55). The invention makes use of the fact that components used for transmitting are, in their nominal output, designed for the worst instance of a low grid voltage. The power reserves arising from grid voltages above a tolerance value can, according to the invention, be used for transmission. This makes it possible to achieve a considerable increase in the transmission output without additional constructional effort. The invention also relates to wind power plant or wind park operated according to the method.
