风电场升压变压器运行方法
摘要：
本发明涉及一种风电场升压变压器运行方法，包括以下步骤：1)、对风电场升压变压器数据以及风功率出力数据进行搜集整理；2)、分析升压变压器运行台数变化时的运行原理，根据并列运行的变压器台数及风功率变化时产生的有功损耗间特性；3)、根据搜集到的风电场的历史风功率出力数据计算出一年中各个月份各个时间段的风功率出力数据平均值，得到风功率出力数据的区间分布特性；4)、根据风功率出力数据的区间分布特性，在风功率小于综合区间内分界点功率的时间段内减少升压变压器的运行台数，满足电网运行经济性的需求。
摘要（英）：

The invention relates to a wind power plant boosting transformer running method. The running method comprises the following steps: 1) searching and arranging wind power plant boosting transformer data and wind power output data; 2) analyzing a running principle when the number of the running boosting transformers is changed, and performing calculation based on the number of the boosting transformers in paralleling operation and active loss characteristics generated when the wind power is changed; 3) calculating a wind power output data average value in each frame in each month in one year according to searched historical wind power output data of the wind power plant so as to obtain interval distribution character of the wind power output data; and 4) reducing the number of the running boosting transformers in the time frames when the wind power is less than demarcation point power in a comprehensive interval according to the interval distribution character of the wind power output data so as to satisfy the requirement of the power gird operational economy.
