Problems solved by technology

[0003] However, the main engine is used to provide power for the ship's navigation, and the auxiliary engine is used to provide power for the ship's electricity. Maintenance costs are also high, so the cost of running the main and auxiliary engines at the same time is high and the exhaust emissions are extremely high
And when the auxiliary engine generates power, it will generate a lot of noise in the engine room, which will affect the ship and the surrounding environment

Embodiment Construction

[0022] see Figure 1 to Figure 3 , an embodiment of a ship main engine power generation system, including a main engine 1 and a synchronous generator 3 . The synchronous generator is a 6-pole or 12-pole low-speed generator. An electromagnetic speed regulating device 2 is arranged between the main engine 1 and the synchronous generator 3, the input shaft 25 of the electromagnetic speed regulating device 2 is connected with the output shaft of the main engine 1 through the first transmission device 4, and the first Transmission device 4 is pulley transmission device, or gear transmission device. The output shaft of the ship's main engine drives the input shaft of the electromagnetic speed regulating device to rotate through gears or pulleys. Of course, the output shaft of the ship's main engine can also be driven by a shaft coupling to rotate the input shaft of the electromagnetic speed regulating device. The output shaft 26 of the electromagnetic speed regulating device 2 is...

Abstract

The invention relates to a power generation system of a marine main engine. The power generation system of the marine main engine comprises the main engine and a synchronous generator. An electromagnetic speed regulating device is arranged between the main engine and the synchronous generator. An input shaft of the electromagnetic speed regulating device is connected with an output shaft of the main engine through a first transmission device. An output shaft of the electromagnetic speed regulating device is connected with a rotor shaft of the synchronous generator through a second transmission device. A speed measuring generator is fixed to the output shaft of the electromagnetic speed regulating device, the synchronous generator, the electromagnetic speed regulating device and the speed measuring generator are connected with a main control electricity box respectively, and the main control electricity box comprises a voltage regulator, a speed regulating controller and a power source circuit. According to the power generation system of the marine main engine, the electromagnetic speed regulating device and the synchronous generator are driven by the main engine to generate constant-frequency power energy. The power generation system has the advantages of saving energy, reducing emission, reducing oil consumption and saving cost.

Description

technical field [0001] The invention relates to the marine field, in particular to a ship main engine power generation system. Background technique [0002] Most of the existing inland waterway ships are equipped with relatively high-power main engines and relatively small-power auxiliary engines, wherein the main engines are used to provide power for ship navigation, and the auxiliary engines are used to provide electricity for ships to generate power. If the main engine is directly connected to the synchronous generator through the coupling, it will also provide power for the ship to generate electricity while providing power for the navigation. This will cause the following problems. The speed of the main engine of the ship sailing in the inland river is generally at 550 to The speed of the ship is adjusted between 1200 rpm, and the speed of the main engine changes greatly. The main engine is directly connected to the synchronous generator through a coupling. When provid...
