Abstract
A controller of a marine main steam turbine gear unit is characterized in that two CPU (central processing unit) cards, three VC cards, three SD (secure digital) cards, two DIO (digital input/output) cards, an AI (analog input) card, an AO (analog output) card and a VOTE card are inserted on a bus board and are integrally mounted in a marine cabinet; the CPU cards are used for completing I/O (input/output) scanning, algorithm execution, third-party equipment communication and online debugging; the VC cards are used for controlling signal output and driving ahead and astern valve positions together with the VOTE card; the SD cards collect three paths of revolving-speed signals respectively; the DIO cards are used for on-off input and output. The controller has the advantages that related operation parameters such as revolving speed of the unit and valve replacement are collected in real time and are subjected to adjustment calculation by an advanced control algorithm, and an analog output channel outputs valve position control signals to an electro-hydraulic actuator to control displacement of a hydraulic servo-motor, so that the opening of a steam inlet valve of a steam turbine is changed, and further, the revolving speed of the unit is finally controlled to adapt to changes of a given value.
