| Abstract: | Digital Electru-Hydraulic(DEH) system is the important apparatus using computer to modulate,surveil and control the turbine.A pure DEH system of low oil-pressure was adopted as the unique control instrument in the reform of No.3 unit of Datun power plant,which realizes the control for rev and load during the start-up,net-joining and load-carrying of the unit,and ensures the well-balanced operation of the unit. The paper Combines with the practical project, and briefly introduces the structure,working principle,reform circs,and application effect of the DEH system. |
