Abstract

The invention discloses an energy optimization and control method of a four-engine double-paddle hybrid power propelling system used for carrying out energy optimization and control on the four-engine double-paddle hybrid power propelling system so as to select and switch 8 station modes. The energy optimization and control method comprises a shipping station recognition process, a load status recognition process and a dynamic energy control process, wherein the shipping station recognition process is to obtain an existing shipping station R by adopting a fuzzy neuroid method, the load status recognition process is to compare an existing load with a light load, a middle load and a heavy load to obtain an existing load status L, and the dynamic energy control process is to preliminarily select control parameters of parts according to the existing shipping station R and the load status L, and optimally distribute system energy and switching to an optimal shipping station by adopting energy management based on a dynamic programming method, so as to realize optimal management and control of energy, and reduce fuel oil consumption and exhaust gas emission furthest when the performance of a dynamical system of the ship is ensured.

Description

technical field [0001] The invention relates to a four-engine double-blade hybrid propulsion system for a ship, in particular to an energy optimization and control method for a four-engine double-blade hybrid propulsion system for a ship. Background technique [0002] Compared with the energy transfer and management process of the traditional ship mechanical propulsion system and the pure electric propulsion system, the diesel-electric hybrid ship propulsion system has a variety of operating conditions, and its energy transfer is more, and the energy management and control are more efficient. for complex. As the International Maritime Organization (IMO) sets more and more stringent requirements on ship emissions and noise, in order to achieve energy saving, emission reduction, vibration and noise reduction of ships, ship hybrid propulsion systems have emerged as the times require. The marine hybrid propulsion system minimizes fuel consumption and exhaust emissions; it has s...
