Abstract
Description
なお、本実施形態では、ガスタービン14と蒸気タービン18が同軸状に設置される構成としたが、これに限られず、ガスタービン14と蒸気タービン18が並列に接続され、各々の駆動により発電する構成としてもよい。
このように、船舶推進装置10は、船舶機器44への電力の供給を最優先とし、余剰電力によって加勢モータ46を駆動させる。
なお、メインエンジン12のプロペラ回転数は一定となるように制御されるため、加勢モータ46により推進用プロペラ29の実回転数が設定回転数よりも上昇する場合は、メインエンジン12の燃料弁を絞りプロペラ回転数を設定回転数となるように制御させる。
よって、船内要求電力量に対し定格負荷が60~85%の間は加勢モータ46で余剰電力の吸収を行うといった運転が可能となり、効率良く運転するための加勢モータ46の起動させるタイミングが定まるため、加勢モータ46の起動制御を容易とすることができる。
加勢モータ46の最大消費電力量としては、例えばタービン発電機20の最大発電電力量が1400KWに対し最大船内要求電力量が700KWとした場合、この差分である700KWとすることができる。また、最大消費電力量がより小さい加勢モータ46を用いるか、設定電力量を最大消費電力量よりも小さく設定することによって、加勢モータ46の最大消費電力量を更に抑えることも可能である。
