PROBLEM TO BE SOLVED: To provide a marine main turbine controller, a marine main turbine facility and a marine main turbine control method carrying out automatic spinning with warming-up effect by reliably rotating a turbine rotor.SOLUTION: A marine main turbine controller 100 carrying out control of a marine main turbine 2 provided with an advancing steering valve 42 and a backing steering valve 44 carries out control to alternately switch opening and closing of the advancing steering valve 42 and the backing steering valve 44 by: opening the advancing steering valve 42 when the marine main turbine 2 stops; fully closing the advancing steering valve 42 when spindle speed of a the marine main turbine 2 reaches a first threshold while the advance steering valve 42 is open and simultaneously opening the backing steering valve 44; and fully closing the backing steering valve 44 when the spindle speed of the marine main turbine 2 while the backing steering valve 44 is open and simultaneously opening the advancing steering valve 42.SELECTED DRAWING: Figure 1
【課題】タービンロータを確実に回転させ暖機効果のあるオートスピンを行う舶用主機タービン制御装置、舶用主機タービン設備、及び、舶用主機タービン制御方法を提供することを目的とする。【解決手段】前進操縦弁42と後進操縦弁44とを備えた舶用主機タービン2の制御を行う舶用主機タービン制御装置100であって、舶用主機タービン2が停止すると、前進操縦弁42を開とし、前進操縦弁42が開の場合に舶用主機タービン2の主軸回転数が第1閾値に到達すると前進操縦弁42を全閉とすると同時に後進操縦弁44を開とし、後進操縦弁44が開の場合に舶用主機タービン2の主軸回転数が第2閾値に到達すると後進操縦弁44を全閉とすると同時に前進操縦弁42を開とし、前進操縦弁42と後進操縦弁44の開閉を交互に切り替える制御を行う。【選択図】図1
