Proportion-Digital Valve Entire Dual Programmable Governor System Control Method Research And System Realization

This article first proposed the main significance and the aim of studying this topic, summarized the development survey of the governor system, and analyzed the hydraulic turbine transient system control principle briefly. The transformation overall plan of the governor system was put forward after analyzing the transformation reason thoroughly in the Capacity enlargement project of the WuJiang hydraulic power station. In view of the proportion - digital valve entire dual programmable governor system control characteristic, carries on the overall system structure the composition, adds the turbine governor system control sequence to carry on the control design, analysis to the design of the remnant pressure and tooth gear frequency measurement regarding its frequency measurement processing , and regarding scene wiring for the oil-break switch etc has carried on the reasonable design, and the stop interlock etc pivotal loop has guarded against designs by mistake. And select the systems control parameter according to the simulation experiment at site, confirm it to satisfy the national standard request through the experiment of recording the wave. This governor system control method research satisfied the specification for the equipment transformation, had certain priority and the rationality, and has obtained the good effect applying in the project practice in sum.
