  "description_excerpt": "The application claims priority to the Chinese patent application No. 202110177632.5 filed on Feb. 9, 2021 and the Chinese utility model application No. 202120361104.0 filed on Feb. 9, 2021, for all purposes, the entire disclosure of which is incorporated herein by reference as part of the present application.\n\nEmbodiments of the present disclosure relate to an electrical system for a mobile power generation device and a mobile power generation device.\n\nWith the development of the power industry, there are more and more devices driven by electricity and scenarios of using electricity. Usually, electricity is provided by fixed power plants and power grids; however, because of various reasons, fixed power plants and power grids cannot meet the power demand of users. For example, when the capacity of the power grids is insufficient or the power generation of fixed power plants is insufficient because of overhaul, failure, lack of fuel and other reasons, the power demand may exceed the capacity of power grids or the power generation of fixed power plants, which may lead to power interruption. For example, when natural disasters such as typhoons and earthquakes damage the power grids or power devices, power interruption will occur. For example, in some construction sites and mine scenes without power grids, there will be situations where the power demand cannot be met or the cost of laying power grids is high.\n\nOn the other hand, mobile power generation device is a kind of power generation device that can be moved or transported.",
