摘要

随着风电装机容量的与日俱增，实现大规模的风电并网是风电发展的必然趋势。然而，由于风能是一种波动性、随机性和间歇性极强的清洁能源，导致风电并网调度异于常规能源。基于此，本文将针对风电场层的有功功率分配开展工作，主要工作概括如下：

(1)对风电机组和风电场展开研究，分析风力发电机组运行特性、风

力发电机组控制策略、风电场的控制策略。

(2)提出了一种简单有效的风电场有功功率分配算法，可以合理利用

各机组的有功容量，优化风电场内有功调度分配指令，减少机组控制系

统动作次数，平滑风电机组出力波动。

(3)优化风机控制算法后，通过现场实际采集数据将所提方法与现有

方法进行了比较，验证了所提方法的合理性。

关键词：风电机组、风电场、有功功率控制、AGC

Abstract

With increasing wind power capacity, to achieve large-scale wind power is an inevitable trend of wind power development. However, since the wind is a volatile, random and intermittent strong clean energy, resulting in wind power dispatch is different from conventional energy sources. And the wind farm is an organic combination for a large number of wind turbines, wind farms under active intelligent distribution layer hair is also included in the grid scheduling section. Based on this, the active allocation and scheduling for grid scheduling side active layer wind farm work, the main work is summarized as follows:

(1)Wind turbines and wind farms to expand research, in-depth analysis of the operating characteristics of wind turbines, wind turbine control strategy, control strategies of wind farms.

(2)This paper proposes a simple and effective wind power active power allocation algorithm, can reasonable use each unit capacity, according to the optimization of wind farms in active dispatching command, decrease The Times of turbine control system action smooth wind power output fluctuation unit.

(3)After optimization of the fan control algorithm, through the practical field data collected will be presented method are compared with those of the existing method, the rationality of the proposed method was verified.

Keywords:wind turbine, wind farm, active power control
