Problems solved by technology
[0004] However, when some current software performs modeling and simulation, the overall fluid network and all internal equipment often use a set of fixed time steps to simulate and solve the ship power system, so the equipment itself has a shorter time step. Matching the time step of the fluid network may cause distortion, divergence, and errors in the simulation calculation of specific phenomena of some equipment, thereby affecting the performance of the overall dynamic operating characteristics of the system

The invention provides a ship power system simulation method, system and device and a medium, and the method comprises the following steps: building a global fluid network model; determining a global fluid network model and a time step length of each device; equipment of which the equipment time step length is smaller than the time step length of the global fluid network model is screened out, the equipment and the fluid network in the surrounding range are set as a local fluid network model, and the part except the local fluid network model is set as a basic fluid network model; the time step of each local fluid network model is set as the time step of the equipment, and the time step of the basic fluid network model is consistent with the time step of the overall situation; when simulation runs to a certain moment, one party runs for an integral multiple of time step length and the other party at least runs for one time step length, and parameter transmission is carried out; and performing simulation debugging, and outputting a convergence result. According to the technical scheme, the accuracy of simulation operation of the ship power system is effectively improved.
Description
technical field [0001] The present application relates to the technical field of simulation of dynamic characteristics of ship power systems, and in particular, to a simulation method, system, equipment and medium of ship power systems. Background technique [0002] For the ship power system, a large number of piping systems (including fuel oil, lubricating oil, steam, cooling water, air, etc.) and equipment (including boilers, main engines, heat exchangers, condensers, etc.) are composed of thermal fluid circulation. In the design, demonstration, evaluation and subsequent training and use of the ship power system, it is often necessary to simulate the overall dynamic operating characteristics of the ship power system system in the form of simulation modeling. The general system-level dynamic simulation is based on the thermal fluid network model. The thermal fluid system of the ship power system can be simulated and solved according to the fluid network model, so as to eval...
