Intelligent LNG power generation ship

Abstract

The invention relates to an intelligent LNG power generation ship. The intelligent LNG power generation ship is provided with an LNG storage tank, an LNG gasification device, a gas generator set, a gas buffer device, a central control device, a power distribution and transformation device, an emergency treatment system, a ship-shore connection system, a load metering device, a condenser, a BOG heater, a booster pump set, a sea water pump set, a BOG storage device, a liquid phase separation device and a gas metering device. According to the intelligent LNG power generation ship, the real-time parameter data of the demand side can be processed by a central processing unit to accurately control the amount of LNG extracted in an LNG tank and accurately control the amount of seawater extractedby a carburetor or the amount of burned natural gas, thereby achieving stable and reasonable gas supply; the final electricity supply meets the demand and the total amount of fuel does not cause any waste; the waste and environmental pollution generated by burning or air emission caused by the excessive pressure in the buffer tank due to excessively large amount of gasification can be avoided.

Description

AI Technical Summary

Problems solved by technology

Although it can realize the functions of power generation and external transmission, it cannot realize the precise control of LNG gasification, power generation and external transmission

When the load demand of the power grid decreases, the existing power generation ships cannot adjust themselves to reduce fuel consumption and total power generation, let alone reduce the total amount of gasified LNG and the amount of seawater pumped for gasification

There is a gap period waiting for manual intervention in energy output and consumption, which will obviously cause a variety of energy waste, safety hazards and environmental pollution risks

For example, if there is too much power generated during the idle period, but there is no load demand, the electric energy can only be lost in the form of heat in the grid; the exce...
