以风电场宏观选址中风能资源评价方法为研究对象,首先考察了不同风电机组的能量转换性能,根据风电机组能量转换性能相似的特点,提出参考风电机组的概念。接着,以发电量为衡量标准,提出将参考风电功率密度作为风电场宏观选址中风能资源评价的指标参数,并给出了该参数的计算方法;通过对实际风电场理论发电量的估算,验证了该指标的可行性。最后,结合风电场容量系数与参考风电功率密度的关系,给出了风电场风能资源的等级划分标准。该文提出的风能资源评价指标和标准,为风电场宏观选址时进行风能资源评价提供了一种具有可操作性、相对简单的实现方法。
Taking wind energy resource assessment method of macro site selection in wind farms as the research object, the energy conversion performance of different wind turbines is investigated first. According to the similar characteristics of energy conversion performance of wind turbines, the concept of reference wind turbine is proposed. Then, based on the power generation capacity as a standard, the reference wind power density is proposed as an index to evaluate the wind energy resources in the macro-site selection of a wind farm and the calculation method of this parameter is given. Based on the theoretical calculation of wind power generation capacity, Verify the feasibility of the indicator. Finally, according to the relationship between the capacity coefficient of wind farms and the reference wind power density, the grade standard of wind energy resources in wind farms is given. The wind energy resource evaluation indexes and standards proposed in this paper provide a feasible and relatively simple method for wind energy resource evaluation during the macro-site selection.
