Power reduction in several wind power plants in a wind park

Abstract

A wind power park and a method for operating a wind power park, the wind power park has a power park master (3) and a plurality of wind power devices (1). The master control (3) of the power generation park predetermines the power output of the wind power generation equipment (1). The wind park can be operated in a normal operating mode and in a power-reduced throttling mode. The park master ( 3 ) outputs a throttling signal to the wind power plants ( 1 ) for this purpose. According to the invention an individual power reduction P is determined for each participating wind power plant by 额定，i : For each wind power plant determine the available power P 可用（i） and reduce this available power by a certain reduction ΔP i ; through the optimized condition T with the same rise time 恢复，优化 = T 恢复，i The optimization method for wind power equipment to determine the reduction ΔP i ; and repeating until the optimization method achieves a predeterminable breakout criterion. A dynamic high-quality regulation behavior of the wind park is achieved not only at power reduction but also at power rise. By taking into account the individual power boost capabilities of the individual wind power plants, the wind power plants simultaneously achieve their respective maximum power outputs. Concomitant negative situations such as overshoot or slow asymptotic approximation are effectively avoided.

Description

technical field [0001] The invention relates to a method for reducing power in a wind park. The wind power generation park includes a power generation park master control and a plurality of wind power generation equipment, and these wind power generation equipment generate and output electric energy. In addition to the normal operating mode, a reduced power operating mode is also possible, in which a signal is applied to the park master to reduce the power of the park and on this basis the wind energy installation throttles its power generation. Background technique [0002] With the development of renewable energy, wind power parks are more used to contribute to grid stability. A wind park realizes its contribution, for example, by regulating the power output, including in terms of real power output. In this context, the demands placed on wind parks with regard to the quality of regulation are becoming ever higher. In particular, higher regulation speeds are required for...
