Design of B737 Simulated Power Supply and Distribution System Based on PLC and LabVIEW

B737客机作为世界范围内使用最多与最成功的商用民航客机,其供配电系统经过市场检验证明了可靠性。随着我国对于民航客机的研制越来越重视,B737客机的供配电系统的研究是十分有必要的。文章参照真实飞机系统构建了基于PLC的B737模拟供配电系统,结合LabVIEW构建相关供配电网络操控系统,并对供配电网络运行原理与故障处理原理进行了分析,根据故障处理原理分析B737飞机供配电系统故障情况下的电网重构过程。通过实验分析,展示了正常状态与故障状态下模拟供配电系统运行状况,为相关人员进行B737供配电系统网络研究提供理论与实际参考。

As the most widely used and successful commercial civil aviation aircraft worldwide,the power supply and distribution system of the B737 airliner has proven reliable by market inspection.As China pays more and more attention to the development of civil aviation aircraft,it is necessary to study the power supply and distribution system of the B737 airliner.This paper constructs the B737 simulated power supply and distribution system based on PLC by referring to the real aircraft system,constructs relevant power supply and distribution network control system combined with LabVIEW,and analyzes the operation principle and fault handling principle of the power supply and distribution network.According to the principle of fault handling,the power grid reconstruction process in the event of a fault in the B737 aircraft power supply and distribution system is analyzed.Through experimental analysis,the simulated operation status of the power supply and distribution system under normal and fault conditions is demonstrated,providing theoretical and practical references for relevant personnel to conduct research on the B737 power supply and distribution system network.
