Whole ship power balance control system and control method for refrigerated container ship

Abstract

The invention discloses a whole ship power balance control system and control method for a refrigerated container ship. The control system comprises an environmental data collector, a cold box controller, a cold box centralized controller, a fan controller, a fan centralized controller and a refrigerated container ship whole ship power balance control system. According to the system and the method, whole ship refrigerated containers are taken as a unified management object, the power consumption of all loads except the whole ship refrigerated containers is predicted, the refrigerated containers are dispatched, a ship power station is controlled, the whole ship power balance control is formed, the states of the refrigerated containers are separately monitored, the refrigerated containers are dispatched, compared with a method of maintaining the power balance of the refrigerated containers, the method of the invention has the advantages that the load prediction of other loads and the control of the ship power station are added, and the effects of reducing an installed capacity and reducing the operating cost are also more remarkable.

Description

technical field [0001] The invention relates to the electric power balance aspect of a refrigerated container ship and the research field of refrigeration control, in particular to a whole ship power balance control system and a control method of a refrigerated container ship. Background technique [0002] Ship power station is one of the important components on board. For refrigerated container ships, it provides necessary power for refrigerated container refrigeration and other electrical equipment, and is the core part of the ship's power system. At present, on a refrigerated container ship, the cooling power of the refrigerated container accounts for about 40% of the total power of the entire ship, and the power of other electrical equipment accounts for approximately 60% of the total power of the entire ship. With the development of container ships in the direction of large size, the number of refrigerated containers that can be loaded is also increasing. The carrying c...

AI Technical Summary

Problems solved by technology

[0003] Under the current design criteria for ship power stations, in order to ensure the safety of the ship's power system, the generator set configuration on the ship must be configured according to the maximum probability working condition of the refrigerated container refrigeration site. The larger the capacity, the greater the redundancy. In this way, on the one hand, the greater the installed capacity of the ship's power station, the cost response of ship construction increases; , increased operating costs
