The mobile energy storage power supply module is arranged on the mobile energy storage vehicle.
As shown in fig. 1, the mobile energy storage power supply sub-module and the fixed energy storage power supply sub-module of the distributed multi-power supply module can be used as power supplies, and can interact with power supplies of an airport power distribution network, a public power grid (local power grid power supply sub-module) and a solar power supply sub-module, a wind power supply sub-module, a water conservancy power supply sub-module, a garbage power generation power supply sub-module and a diesel generator power supply sub-module.

As shown in fig. 1, each control sub-module and each power supply sub-module perform information interactive management, and each control sub-module can still complete power supply energy management and operation optimization of the airport power supply system under the condition that the remote centralized control background fails. The management software of the centralized control background integrates the working state, current, voltage and other information of each distributed multi-power supply module, can be combined with the historical power utilization condition of the airport power utilization system to pre-judge the power utilization load of the airport power utilization system, automatically controls the input and the output between each power supply module and the airport power utilization system through the intelligent control module, and can also control the input and the output of each power supply module manually by remote control personnel in the application of the centralized control background.
As shown in fig. 1, when the power supply system of the airport works normally, the control submodules of the intelligent control module and the power supply submodules of the distributed multi-power-supply power supply module collect the operating current and the operating voltage of the power supply submodules in real time, the operating states of the power supply submodules are interacted with information of centralized control background software in a wired or wireless manner, and the information interaction among the control submodules can be realized. In the invention, the intelligent control module preferentially controls the solar power supply module, the wind power supply module, the water conservancy power supply module and the garbage power supply module to supply power for the airport load.
As shown in fig. 1, in application, when various data of the power supply load of the local power grid power supply sub-module are ideal and the electric energy of the fixed energy storage power supply sub-module is low, the local power grid power supply control sub-module of the intelligent control module controls the local power grid power supply sub-module to be in a main use state to supply power to the airport load; the intelligent control module respectively controls the solar power supply sub-module, the wind power supply sub-module, the water conservancy power supply sub-module and the garbage power generation power supply sub-module, and a single or a plurality of power supply sub-modules with better power supply and electric energy quality charge the fixed energy storage power supply sub-module. After the fixed energy storage power supply sub-module is charged, if the intelligent control module detects that the electric energy quality of each module of the solar power supply sub-module, the wind power supply sub-module, the water conservancy power supply sub-module and the garbage power supply sub-module is still good, the intelligent control module controls one or more sub-modules with good electric energy quality of the solar power supply sub-module, the wind power supply sub-module, the water conservancy power supply sub-module and the garbage power generation power supply sub-module to be in a main use on one hand, and supplies power for airport loads; on the other hand, the intelligent control module cuts off local power grid power supply sub-modules, starts a grid connection function, and sends electric energy generated by one or more of the solar power supply sub-modules, the wind power supply sub-modules, the water conservancy power supply sub-modules and the garbage power generation power supply sub-modules into the local power grid for local users to use.
As shown in fig. 1, in practical application, when the mobile energy storage power supply sub-module has a poor electric quantity and needs to be charged, the intelligent control module preferentially controls the solar power supply sub-module, the wind power supply sub-module, the water conservancy power supply sub-module and the garbage power generation power supply sub-module to charge the mobile energy storage power supply sub-module, and after charging is completed, the intelligent control module automatically stops a charging procedure; if the electric energy quality of the solar power supply sub-module, the wind power supply sub-module, the water conservancy power supply sub-module and the garbage power generation power supply sub-module is poor, the intelligent control module controls the local power grid power supply sub-module to charge the mobile energy storage power supply sub-module, and after charging is completed, the intelligent control module automatically stops a charging program. When a local power grid power supply sub-module has power failure or poor power quality, meanwhile, the solar power supply sub-module, the wind power supply sub-module, the water conservancy power supply sub-module and the garbage power generation power supply sub-module are poor in power quality and difficult to meet airport load application, the fixed energy storage power supply sub-module is preferentially adopted to supply power to an airport load, if the fixed energy storage power supply sub-module is poor in power quality and cannot meet load requirements, the intelligent control module firstly starts the mobile energy storage power supply sub-module to supply power to the airport load, and when the load use cannot be met, the intelligent control module starts the diesel generator power supply sub-module to serve as a main use to.
As shown in fig. 1, in the invention, a remote centralized control background monitors the operation condition of each distributed multi-power supply module in real time through an intelligent control module, data includes operation current, operation voltage and the working state of a power supply module, the centralized control background collects, analyzes and stores the data, and pre-judges the power load by adopting technologies such as big data, internet of things and the like and intelligent methods such as a neural network and the like, and performs energy management and operation optimization, visual protection and control on an airport power supply system to realize the optimized operation of the power supply system. Under special conditions, airport personnel can carry out switching control on each distributed power supply module through a remote centralized control background remote control or an intelligent control module on site, manual switching belongs to the highest priority, and optimal automatic switching control of each power supply module of the system can be locked. In practical cases, the optimized automatic switching control of each power supply sub-module of the system can be started only when the manual authorization allows.
