The Realization of Improved Power Regulation Control Structure and The Frequency Primary Regulation for Hydraulic Turbine Governor

针对现有调速器功率调节的参数通用性低,难以满足不同工况下功率调节和一次调频要求的问题,本文提出了一种改进型功率调节控制结构,幵在此基础上采用功率偏差增量式PID算法,建立了新的水轮机调速器功率调节模型。电站投运结果表明该方法参数调整方便,通用性强,能够较好的满足水力发电厂关于功率调节及功率模式下一次调频的要求。

For the existing governor power regulation parameters have low generalities and cannot meet the requirements of the power regulation and the frequency primary regulation under the different work condition, the article proposes a improved power regulation control structure, and adopts the power offset increment PID algorithm to build a new type turbine governor power regulation model. According to running result of the power station which adopts the improved control structure, the governor parameters have high generalities and are easy to adjust, and can meet the requirements of the power regulation and the frequency primary regulation under the different condition.
