Description

Technical field [0001] The invention relates to a power system simulation technology, in particular to a method for modular simulation of a ship's power system. Background technique [0002] The simulation link plays an indispensable role in the development of the shipbuilding industry. In the past when the ship power system was small in scale, full physical models or mathematical and physical hybrid models were used to simulate the actual system for analysis. However, with the continuous development of science and technology The development of power electronics technology is widely used in ship power systems, which makes the scale and complexity of ship power systems increase day by day. The above simulation analysis methods are difficult to adapt to this large-scale and complex ship power system network. [0003] In today's simulation of large-scale and complex ship power systems, digital simulation technology with good economy and practicability has been widely used by ship powe...

Problems solved by technology

[0009] However, these software are designed according to the land power system simulation scheme and are not specific to the ship power system. Many unique modules of the ship power system need to be built by themselves, such as propeller modules and special load modules. Secondly, the modeling process and conversion of power equipment The model process under the simulation platform used by Cheng is cumbersome and complicated, which brings a lot of inconvenience to the simulation researchers of the ship power system
