Power positioning ship energy management optimization method with automatic fault isolation function

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.

Description

technical field [0001] The invention relates to a ship energy management system, in particular to a dynamic positioning ship energy management optimization method with automatic fault isolation. Background technique [0002] Ship energy management refers to the unified dispatch, management and control of ship electric energy generated according to the actual needs of the ship power system. Its purpose is to comprehensively consider the maneuverability of the ship, economy, and the stability and reliability of the power grid operation according to the actual working conditions of the ship, coordinate and control the electrical equipment, realize the optimal allocation and management of electric energy, and take into account the economical power on the basis of continuous stability and safety. type to ensure the minimum energy consumption of the ship. [0003] Genset scheduling has been widely used on land. After the State Council promulgated the "Measures for Energy-Saving ...

AI Technical Summary

Problems solved by technology

[0005] At present, the main method of ship generator set scheduling is to ignore the energy consumption characteristics of each generator set and distribute the load of each generator set in equal proportions, which will easily lead to high energy consumption and heavy pollution of ships

Although the scheduling method of onshore generating sets can reduce the energy consumption of ships and achieve a certain optimization effect, it has not been properly improved for the ship power grid and cannot meet the requirements of ship energy management optimization.
