Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0042] To sum up the problems faced by ship load forecasting. Divide the ship load into two parts. The prediction method of machine learning is still used to predict the basic equipment of the ship and domestic electricity consumption. Since this part of the power loss is hardly affected by the external marine environment. A model for estimating power consumption is established by combining the power consumption model with the ship motion model and considering the marine environmental load on the electric propulsion load.

[0043] In order to achieve the above object, the present invention adopts the following technical solutions:

[0044] 1) According to the actual navigation status of the ship, through statistics and integration of the historical data of the ship's basic equipment and domestic power load. For cruise ships, tempe...

Abstract

The invention provides a comprehensive power load prediction method for an electric propulsion ship, and the method comprises the steps: carrying out the prediction of an electric propulsion load andship basic equipment and living power prediction, and calculating the ship basic equipment and living power prediction through a deep learning algorithm, wherein the electric propulsion load prediction comprises ship movement caused by external force and thrust required for maintaining ship propulsion; the ship motion caused by the external force comprises wave model establishment, wind energy model establishment and ocean model establishment; and the thrust required for maintaining the ship propulsion comprises a main thruster and a ship head thruster. The characteristics of an electrically-propelled ship are fully taken into account, and accurate load prediction is realized.

Description

technical field [0001] The invention relates to a comprehensive electric load forecasting method, in particular to a comprehensive electric load forecasting method for electric propulsion ships. Background technique [0002] At present, with the development of large-scale and multi-functional ships, the demand for large and super-large ships in ocean transportation is increasing, and the requirements for ship power systems are also getting higher and higher. Accurate load forecasting can reduce the cost of power system operation. There are many situations in which the ship power system is in dynamic changes, and the dynamic range of the system is also relatively large. These directly affect the stability of the power grid. We need to make timely predictions on the changes in the ship's power load, and then carry out power dispatching of the power grid. , so that the impact of load changes on the power grid can be controlled within a reasonable range to ensure the economical...
