Abstract

The invention relates to a speed regulation control system based on a marine dual-power output unit. One end of a steam turbine is connected with a generator through a coupler, and the other end is connected with a feed pump device through a magnetic coupler. A speed regulation control device of the double-power output unit changes the steam admission amount of a steam turbine by adjusting the opening degree of an adjusting valve hydraulic servo-motor device connected with the steam turbine, the rotating speed of the steam turbine is controlled, and therefore the rotating speed of a generator is stabilized within the required range. The speed regulation control device of the double-power output unit is connected with the feed pump through the magnetic coupler in the feed pump device, the rotating speed of the feed pump is controlled by controlling the air gap of the magnetic coupler, the effect of regulating the feed water flow is achieved, and therefore the control device of the double-power output unit can control the rotating speed of the steam turbine and the rotating speed of the feed pump at the same time. Two control modes are integrated into the same control device, the function of double-power output of one unit is achieved, the miniaturization and light-weight design of the unit is achieved, and the space utilization rate and the power density are improved.

Description

technical field [0001] The invention relates to a ship auxiliary steam turbine, in particular to a speed regulating control system of a ship auxiliary steam turbine. Background technique [0002] Traditional steam turbine control and feed water pump control are independent of each other. The control device of the steam turbine generator set controls the speed of the steam turbine independently, and the control device of the steam turbine feed water pump set controls the speed of the feed water pump independently. The control methods of the two types of equipment are not connected and independent of each other. [0003] At present, there is no speed regulation control system and method for marine dual power output units in China. Contents of the invention [0004] The present invention aims to provide a speed regulation control system based on a marine dual power output unit, which is used to solve the problem that a conventional control device cannot simultaneously contro...
