Description
technical field [0001] The invention relates to a marine power plant, in particular to a marine hybrid power plant. Background technique [0002] With the increasingly strict marine emission regulations, the issue of ship pollutant emission has been paid more and more attention by the shipping departments of various countries. Moreover, the continuous development of global trade has also put forward higher requirements for the carrying capacity of ships. Although the traditional diesel engine propulsion method can quickly meet the load demand during the navigation of the ship, it has shortcomings such as low energy utilization rate, excessive fuel consumption and excessive noise during operation. Although electric propulsion has the advantages of cleanliness, fast response, and high operating efficiency, it has disadvantages such as poor endurance, frequent switching of operating conditions, which is easy to cause damage to the ship's power grid, and high operation and main...
