Abstract
Description
Technical Field
[0001] The present application relates to the technical field of shipbuilding, and particularly to a modeling method for a ship power system. Background Art
[0002] The ship power system has characteristics such as complex composition, numerous devices, and high coupling degree, which pose great challenges to the modeling and simulation of the system. In traditional modeling methods for ship power systems, the total parameter method or one-dimensional method is mainly used for simulation modeling, that is, modeling and calculating the main devices of the power system. Although the above traditional methods can describe and analyze the steam power system to a certain extent, in practical applications, they have obvious limitations. On the one hand, it is difficult to meet the actual requirements in the response speed of the calculation results. For example, when the working conditions change rapidly, the traditional model often cannot quickly give an accurate response. On the other hand, there are also deficiencies in the calculation accuracy.

Among them, the operating condition information contains all the key information of the target system operating under different operating conditions. When the operating conditions of the target system are different, at least some of the equipment parts have different performance parameters under different operating conditions.

[0088] Among them, the total resistance coefficient is the sum of the friction resistance coefficient and the local resistance coefficient. Based on the total resistance coefficient, the medium pressure loss data can be calculated using the Darcy formula.
[0089] Among them, the pipeline flow parameter data is the theoretical calculation value of the pipeline model. By comparing the simulation results of the management model with the theoretical calculation value, the accuracy of the established pipeline model can be verified to ensure that the established pipeline model is accurate and reliable.
[0090] In an alternative embodiment, the step of verifying the pipeline model in steps S61 to S63 can be performed after step S6. Optionally, after constructing the target system model, the following steps are further included: performing a simulation calculation on the established target system model; obtaining the simulation results of the pipeline model according to the simulation results of the target system model.
