Embodiment Construction

[0027] Below in conjunction with accompanying drawing, the technical scheme of invention is described in detail:

[0028] The dynamic planning and management method of aircraft power grid is as follows: figure 1 shown. The input is the description of the power grid structure, the description of the constraints, and the power supply capacity of the power system, the working status of the power supply system, and the flight phase of the aircraft. The distribution network management is approximated as a multi-level optimal decision-making problem, with a specific performance index of the power grid as the power grid management goal, and under the inherent constraints of aircraft power grid management, according to different flight states and flight stages, step-by-step decisions are made to select secondary power generation The optimal power supply path from the aircraft to the load end is obtained, the optimal grid structure scheme is obtained, the control signal of the aircraf...

Abstract

The invention discloses an aircraft power supply network dynamic programming management method, mainly solves problems that an aircraft power supply network conventional management method is high in workload and low in operation speed and has no generality of different aircraft types, and belongs to the technical field of aircraft power supply network management. The optimal control theory is applied to aircraft electric energy management, the dynamic programming power supply network management method is applied to realize aircraft power supply network management, the optimal power supply structure of a power supply network is acquired, and redundant power supply and fault-tolerant reconstruction of the power supply network can be realized. Besides, the management method is simple and great in generality. A method of exhaustion can be effectively replaced by the method so that aircraft power distribution network automatic management is realized, reliable power distribution of the power supply network is guaranteed, and the novel method is provided for multi-electric-aircraft multichannel complex power supply network management.

Description

technical field [0001] The invention discloses a method for dynamically planning and managing an aircraft power grid, which belongs to the technical field of management of multi-electric aircraft power grids. Background technique [0002] With the development of more electric aircraft, the complexity of the aircraft power supply system, the increase in the number of onboard electric drive loads, and the increase in the demand for electrical power, the requirements for power grid management of the electrical system of more electric aircraft are gradually increasing. Therefore, it is necessary to propose a more optimized power grid management strategy to realize the selection of power supply and distribution paths, the control of each contactor in the distribution network, and the fault-tolerant reconstruction of the distribution network under fault conditions to ensure the uninterrupted power supply of key loads. Power grid management is an important means to improve the reli...
