Dealing with the rebuilding project of the governing system of unit3 in Xinjiang Manas Power Plant

this paper gives the transformation scheme and the control functions of the digital electro-hydraulic(DEH) control system.Applying the principle of the automatic control system

it presents the mathematical modeling of the DEH system.After the unit being transferred

the test

that the unit suddenly discharges the load

makes out that the transformation is successful and it satisfies design demands.
