[0002] The marine power station system is the power generation and power supply equipment on board, and is one of the most important systems on board. After the power station system is installed on board, it needs to be debugged and tested, and then mooring test and navigation test are carried out. The land joint commissioning is to pre-commission and test the equipment that constitutes the shipboard power station system, such as diesel generator set, main switchboard, power station monitoring device, insulation monitoring device, etc., at the land joint commissioning site.

[0003] Since the equipment of the entire power station system is widely distributed on the ship, and the space on the ship is small, it is inconvenient to inspect and maintain it. In addition, since the entire power station system is composed of many devices, each device has many direct wiring and communication interfaces, which are prone to errors and failures. Therefore, in order to facilitate the inspection of the technical status and performance indicators of the power station system before loading, it is very necessary to conduct joint commissioning tests on the entire power station system in a simulated ship environment at the onshore joint commissioning site, which is convenient for fault query and elimination, and can also save time for commissioning the power station system after loading.
