Shore power system for gas vessel

Abstract

The invention relates to a vessel power supply system with gas power generation as a power supply, in particular to a shore power system for a gas vessel. The shore power system for the gas vessel comprises gas high-voltage generator units, a high-voltage wire outlet cabinet, a high-voltage connection box, a high-voltage cable reel winch and a shipborne transformer substation, wherein the gas high-voltage generator unit comprises a gas engine, a high-voltage generator, a PLC and a photovoltaic conversion module, the high-voltage cable reel comprises a machine frame, a reel winch and a motor, the shipborne transformer substation comprises a high-voltage wire inlet and outlet cabinet, a transformer, a low-voltage wire inlet and outlet cabinet and a power distribution cabinet. By the adoption of the shore power system for the gas vessel, detection and judgment can be conducted according to the real-time load condition of vessel signal transmission, the number of the gas high-voltage generator units to be stopped and the number of the gas high-voltage generator units to be started are selected according to real-time work condition, power consumption can be controlled more effectively, and waste is reduced. The high-voltage connection box is reasonable in structure and convenient to use. Meanwhile, due to the adoption of the PLC, manual operation of personnel is not needed, and the operability is high.

Description

technical field [0001] The invention relates to a ship power supply system using gas power generation as a power source, in particular to a shore power system for a gas ship. Background technique [0002] The shore power system can realize the direct connection of the ship to the shore power supply of the dock when the ship is berthed, and obtain the power required by the ship's pumps, ventilation, lighting, communication and other facilities from the shore power system without using its own diesel generator set to generate electricity by itself , greatly reducing air and noise pollution. At present, the shore power system is an important form of shore power used by ships. It is in the leading position in the industry with its simple and fast operation mode, good economy and practicability. With the development and promotion of shore power technology, the scope of using shore power system It will become larger and larger, and it is expected to become the mainstream of elect...
