Problems solved by technology

For the navigation energy prediction of electric cruise ships, the important influencing factors are cruise ship navigation speed, followed by hydrological conditions and channel information. The energy estimation method in the above patent is not suitable for ship navigation energy prediction, so it is necessary to invent an electric ship Navigation Energy Consumption Prediction Method

Embodiment Construction

[0062] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0063] A method for predicting and controlling energy consumption of an electric cruise ship, the steps are as follows:

[0064] S1. Set cruise sailing time

[0065] The cruise line is fixed, such as figure 1 As shown, the sailing process includes uplink, docking and downlink, where the uplink time is recorded as T 1 ,T 1 ∈[5,7], the docking time is denoted as T 2 ,T 2 ∈[1.5,2], the downlink time is denoted as T 3 ,T 3 ∈[3,5]; the total sailing time is recorded as T 0 ,T 0 =T 1 +T 2 +T 3 ,T 0 ∈[9.5,13], the unit is h;

[0066] S2. Obtain navigation information in real time

[0067] Obtain the channel information of the route from the shore monitoring system, including the location information of the congested segment and the recommended speed of the segment, divide the route into n segments according to the channel information, a...

Abstract

The invention discloses an electric cruise ship navigation energy consumption prediction and control method. The method comprises the following steps: S1, setting cruise ship navigation time; S2, acquiring navigation information in real time; S3, loading historical navigation information; S4, calculating total energy consumption required by cruise ship navigation; S5, calculating uplink and downlink energy consumption of the cruise ship; S6, cruise ship navigation speed planning: according to the calculation formula of the total energy consumption of navigation and the energy consumption of the ascending and descending processes, combining with the constraint condition, taking the minimum total energy consumption required by the navigation of the cruise ship at the t moment as a target condition, calculating to obtain the current optimal speed value of the cruise ship, and meanwhile, obtaining the minimum total energy consumption required by the cruise ship at the t moment; s7, planning the openness of recreational facilities; and S8, cruise ship navigation energy consumption control: controlling the cruise ship navigation speed and the recreational facility power according to the ascending or descending real-time navigation speed calculated by the system and the recreational facility openness.

Description

technical field [0001] The invention belongs to the field of control of electric cruise ships, and in particular relates to a method for predicting and controlling energy consumption of electric cruise ships. Background technique [0002] Faced with the increasing pressure of energy saving and emission reduction in the shipping industry, many countries around the world have implemented strict ship emission standards, forcing ship manufacturing to change to a cleaner direction. The electrification of cruise ships is an inevitable trend of future development. At present, most cruise ships in my country use diesel engine power systems, which generate a large amount of oily water, harmful gases and particulate matter during navigation and port entry, which have a serious impact on the ecological environment of water areas. [0003] Electric cruise ships are driven by lithium batteries. Compared with 2,000-ton fuel-powered ships of the same scale, they can save nearly 100 tons o...
