Abstract

The invention relates to a power positioning ship energy management optimization method with an automatic fault isolation function. The method comprises steps of carrying out dispatching according to energy consumption characteristics of generating units and output proportion of thereof; taking the combination of products of the ratio of output power to biggest power of each generating unit and the ratio of rated power of each power generator to the biggest power generator rated power as a feasible solution, and by use of the genetic algorithm, searching a gregarious optimal solution; using an observation device to observe operation sates of each generating unit, and when a generating unit fails, automatically disconnecting the failed generating unit, thereby finishing fault isolation; and re-scheduling the rest generating units, thereby ensuring safety and stability of the ship power grid. According to the invention, load of each ship generating unit is properly distributed, so the safety of the ship power grid is ensured, power consumption of ships is reduced and objectives of reducing ship operation cost and ship pollution are achieved.
