0903号台风对我国海上风力发电的影响

基于CCMP(cross-calibrated multi-platform)再分析风场数据,研究了0903号台风经过前后21天对我国东部5个海上风电场的影响。发现:风机的输出功率受其所处台风场的相对位置影响,台风北进过程中前沿(后沿)在2009年6月18—19(27—28)日使得风机输出功率显著增加,而6月22—23日,台风中心进入东海时, 5个站位风机输出功率最低。唐山市海港区S1站单机运营能力最低(64.3%)且额定容量最低(0);嘉兴市平湖县S4站单机运营能力最高(88.1%);南通市如东县S3站单机额定容量最大(13.1%)。0903号台风过境整个过程中,风速未超过风机的切出风速,对我国东部海洋风力发电场,提高了发电量。

Impact of typhoon No.0903 on offshore wind power generation in China

Wind data from the Cross-Calibrated Multi-Platform (CCMP) for Typhoon No. 0903, generated in the South China Sea, was analyzed for the 21-day wind field through the period of the typhoon''s passage over five offshore wind power plants. The CCMP data showed that the output power of the wind turbines was affected by the position of the typhoon wind field relative to the turbines'' location. The front edge (back edge) of the typhoon introduced a significant increase in the output power of the wind turbines on June 18-19 (27-28), 2009. On June 22-23, when the typhoon center entered the East China Sea, the output power of the five stations was lowest. Haigang S1 station in Tangshan city had the lowest single machine operating capacity (64.3%), and its rated capacity was lowest (0); Pinghu S4 station in Jiaxing City had the highest single machine operating capacity (88.1%); Rudong S3 station in Nantong City had the largest single machine rated capacity (13.1%). Over the whole passage period of typhoon No. 0903, the wind speed did not exceed the cut-out wind speed, and power generation was increased for the offshore wind farms in the eastern part of China.
