  1. There is difference frequency measurement requirement for every part of pid regulating, difference between dynamic quality and static quality in response time and accuracy. according to these, it use the interrupt functions and high - speed counter of the simens s7 - 200 plc cpu226 basic unit and some peripheral circuit to measure frequency ; in software designed, the procedure frame of hydraulic - turbine governor and disperse process of parallel pid are analyzed, an improved pid algorithm is adopted to realize a pid regulation mode with variable structure and parameters ; the mechanical liquid - pressure system of the hydraulic - turbine governor is with electric - hydraulic converter unit of step motor. according to the drive character of five phase of response step motor, a variable frequency regulated voltage driver unit is designed in order to realize interface between plc and driver of step motor

    本文利用s7 - 200plc自身的特點設計了頻率測量單元,根據pid調節各個環節的特點,以及調速器動態特性、靜態特性對頻率測量的實時性和精度要求的不同,利用s7 - 200plc基本單元中內置的高速計數器以及相應的外圍放大整頻電路,實現了水輪發電組頻率的測量;在軟體上,對微調速器的整個程序框架、並聯pid的離散化過程進行了析,用改進的pid演算法實現了變參數、變結構的pid調節模式;調速器的械液壓隨動系統具有步進電電液轉換元件,採用五相反應式步進電,根據其驅動特性設計了變頻調壓驅動器,實現plc與步進電驅動器間數介面。
