摘要

调节死区和调速器下垂是火电机组一次调频中的两个重要性能指标。调节阀的煤质、运行方式、非线性等因素可能导致调频性能指标与设定值存在偏差。本文根据发电机组的日常运行数据，得到了静态频率特性曲线，并提出了估计机组死区和调速器下垂的方法。通过工业实例验证了该方法的有效性。

Performance assessment of primary frequency regulation based on static characteristics

Regulation deadband and speed governor droop are two important performance indicators in the primary frequency regulation of thermal power unit. Coal quality, operation mode, and non-linearity of a regulating valve may cause the deviation between the frequency modulation performance index and the set value. In this paper, a static frequency characteristic curve is obtained from the daily operation data of the generator unit, and the method of estimating the deadband and the speed governor droop is proposed. The effectiveness of the proposed method is verified by industrial examples.
