【摘要】：开展长年代风能资源评估可为海上风电场的可行性研究和风险评估提供依据和支撑。创新性地引入了气候预测系统再分析(CFSR)数据,以江苏响水海上风电场为例开展了长年代风能资源评估,结果表明:CFSR数据10 m高度风速与海上气象塔10 m高度风速的平均偏差为-0.2 m·s~(-1),均方根误差为1.9 m·s~(-1);CFSR数据10 m高度风速与海上气象塔90 m高度风速的相关系数范围在0.359~0.619,相比气象站的相关系数提高了40%~90%;长年代订正得到海上气象塔90 m高度近30 a的风数据,多年平均风速为6.9 m·s~(-1),标准差为0.2 m·s~(-1)(2.9%);测算出海上风电场近30年的等效满负荷小时数,多年平均值为2 423 h,标准差为112 h(4.6%);评估出25 a一遇(海上风电场的寿命期)、10 a一遇、5 a一遇的最小年平均风速分别为6.6、6.7和6.8 m·s~(-1),最小年等效满负荷小时数分别为2 227、2 280和2 329 h。利用CFSR数据开展海上风电场长年代风能资源评估在技术上是可行的。
[Abstract]:The long-term wind energy resource assessment can provide the basis and support for the feasibility study and risk assessment of offshore wind farms. Taking Xiangshui offshore wind farm in Jiangsu province as an example, the long-term wind energy resource evaluation is carried out. The results show that the average deviation between the wind speed of 10 m height and the wind speed of 10 m height of the offshore meteorological tower is -0.2 m 路s-1). The root mean square error is 1.9 m 路s ~ (-1); The correlation coefficient between the wind speed of 10 m height and the wind speed of 90 m height of the marine meteorological tower is in the range of 0.359 ~ 0.619, which increases the correlation coefficient of the meteorological station by 40 ~ 90% compared with that of the meteorological station. The annual mean wind speed is 6.9 m 路s-1, and the annual mean wind speed is 6.9 m 路s-1). The standard deviation is 0.2 m 路s ~ (-1) and 2.9m 路s ~ (-1). The equivalent full load hours of offshore wind farm for nearly 30 years are calculated. The annual average value is 2 423 h, and the standard deviation is 112 h / 4. 6%. It is estimated that the minimum annual mean wind speed of the offshore wind farm is 6.66.7m 路s-1 and 6.8 m 路s-1, respectively, for the life cycle of the offshore wind farm (the minimum annual mean wind speed is 6.66.7m 路s-1 and 6.8 m 路s-1, respectively). The minimum annual equivalent full load hours are 2227 2280 h and 2 329 h, respectively. It is technically feasible to use CFSR data to evaluate the wind energy resources of offshore wind field for a long time.
