【摘要】 从多台二次再热机组一次调频的试验结果看,二次再热机组的一次调频能力明显弱于同容量的一次再热机组,难以达到考核标准的要求。通过分析现行一次调频考核标准的制定原理,并根据二次再热机组的结构特性,采用数理模型计算其一次调频性能,为探讨现行标准下二次再热机组一次调频能力提供依据。更多还原

【Abstract】 According to the test results of primary frequency control of several double reheat units,the primary frequency control performance of double reheat units is obviously weaker than that of single reheat units with the same capacity,and it is difficult to meet the requirements of assessment standards. The formulation principle of the current primary frequency control assessment standard was analyzed.The numerical model was used to calculate its primary frequency control performance according to the structural characteristics of the double reheat unit.It provides a basis for discussing the primary frequency control performance of the double reheat unit under the current standard.更多还原
