Embodiment Construction

[0020] In order to further illustrate the technical means and functions adopted by the present invention to achieve the intended purpose, the present invention will be described in detail below in conjunction with the accompanying drawings and flow charts.

[0021] The principle diagram of the present invention is as figure 1 shown, including the following specific steps:

[0022] The main control system 1 of the ship is responsible for controlling the work of the diesel engine 2 and the transmission system 4. The auxiliary power system used for starting and stopping the ship is introduced compared with the ordinary diesel main engine transmission system. The system processor 3, the frequency converter 5, and the high-torque AC motor 6 , Supercapacitor energy storage system 7.

[0023] The system processor 3 is responsible for monitoring the speed change command sent by the ship main control system 1 to the speed change system 4, and is responsible for identifying the curren...

Abstract

The invention provides an auxiliary power system for starting and stopping of a ship. As shown in a first figure, a ship master control system 1 is in charging of controlling work of a diesel engine 2 and work of a speed changing system 4. According to the auxiliary power system for starting and stopping of the ship, a system processor 3, a frequency converter 5, a large-torque alternating current motor 6 and a super-capacitor energy storage system 7 are introduced. The system processor 3 is in charge of monitoring a speed changing command sent by the ship master control system 1 to the speed changing system 4, identifying the current work state of a ship main machine, sending a command to control the frequency converter 5 according to obtained starting and stopping information and the power, rotation speed and torque of the diesel engine so as to drive the large-torque alternating current motor 6 connected to a drive spindle in series. After supplementing the power and torque to the spindle, the large-torque alternating current motor 6 drives a propeller 8. The power requirement of the large-torque alternating current motor 6 is met through the super-capacitor energy storage system 7. In a stable running period, the large-torque alternating current motor 6 is controlled by the system processor 3 to charge the super-capacitor energy storage system 7.

Description

technical field [0001] The invention relates to the technical field of mechatronics and automation, in particular to an auxiliary power system for starting and stopping a ship Background technique [0002] With the development of social economy and industrialization, the international oil price rises rapidly, and the fuel cost of ships increases day by day. Therefore, ship energy-saving technology has become one of the hot spots in the research of shipping industry and shipbuilding industry. At present, my country's energy situation is severe, and energy conservation and emission reduction have become an extremely important task for the development of the national economy. The ship itself is a means of transportation with high energy consumption. Therefore, the research and application of energy-saving technology to reduce the energy consumption of ships can not only save a lot of fuel costs for shipping companies, but also reduce environmental pollution caused by ships runn...
