A Network Fault Reconfiguration Method Applicable to Aircraft Distributed Power Distribution System

Abstract

The invention discloses a network failure reconstruction method suitable for an airplane distributed distribution system. The method comprises the following steps of: setting a corresponding intelligent agent for each distribution element of a power distribution network in a control layer; making an agent action rule and an information interactive coordination strategy according to position distribution of distribution elements in the network; synthesizing and releasing a working condition of the distribution element corresponding to each intelligent agent by using each intelligent agent, informing an adjacent agent of power supply service which can be provided by the intelligent agent, and making a power supply service request by using the adjacent agent; and perceiving a state which is released by the adjacent agent and responding by using each agent, and responding to the power supply service request which is made by the adjacent agent, and generating a control command corresponding to the distribution element according to the certain response action rule and the coordination strategy. The method has the advantages of better solving the problem of the conventional failure reconstruction algorithm, automatically tracking and monitoring the topology and the working condition of a network, and restoring power supply for a loading point in the network as far as possible on the premise that a failure in the network is ensured to be isolated.

technical field [0001] The invention relates to a network system control method, in particular to a network fault reconfiguration method. Background technique [0002] At present, known fault reconstruction algorithms for power distribution networks include modern stochastic optimization algorithms and fault recovery scheme preset methods. Since modern stochastic optimization algorithms need to collect the working status of the entire network to make control decisions, they are more suitable for centralized control methods, while aircraft power distribution systems often use distributed control methods to improve system reliability, so modern stochastic optimization algorithms are not applicable Because of the control of the aircraft power distribution system, and because the important equipment on board has high requirements for uninterrupted power supply, the modern stochastic optimization algorithm cannot meet the real-time requirements of the system due to its large amou...

Since modern stochastic optimization algorithms need to collect the working status of the entire network to make control decisions, they are more suitable for centralized control methods, while aircraft power distribution systems often use distributed control methods to improve system reliability, so modern stochastic optimization algorithms are not applicable Because of the control of the aircraft power distribution system, and because the important equipment on board has high requirements for uninterrupted power supply, the modern stochastic optimization algorithm cannot meet the real-time requirements of the system due to its large amount of calculation

The fault recovery plan preset method is generally used on aircraft for reconstruction and recovery, but the problem with this method is that when the network is relatively large, it is difficult to take all fault situations into consideration and formulate a recovery plan. When multiple faults and chains occur in the system When the failure situation exceeds the preset solution, the controller cannot perform reconstruction and recovery management on the system
