摘要
针对试飞中机载电源系统中三相交流电源参数的测试需求,设计了基于FPGA的三相交流电源参数测试系统,实现对飞机三相交流系统稳态和瞬态特征参数进行采集、分析计算、数据传递和存储等功能。该系统可以用来分析检测飞机三相交流供电系统的电源品质,在飞行试验中对机载供电系统进行关键参数测试,通过分析对机载供电系统进行设计优化。通过动态信号分析仪对交流电源参数测试系统进行系统测试,比对该方法与标准仪表测试的畸变系数,通过误差分析,均低于0.5%,满足国军标测试要求,对飞机电源系统有一定的应用价值。
This paper is designed to test the three-phase AC power supply parameters in the airborne power system of the test flight.The three-phase AC power supply parameter test system based on FPGA is designed to collect and analyze the steady-state and transient characteristic parameters of the three-phase AC system.Functions such as calculation,data transfer,and storage.The system can be used to analyze and detect the power quality of the aircraft three-phase AC power supply system.In the flight test,the key parameters of the airborne power supply system are tested,and the design of the airborne power supply system is optimized.The system is tested by the dynamic signal analyzer on the AC power parameter test system.The distortion coefficient of the method and the standard instrument test is less than0.5%,which meets the national military standard test requirements.which has certain application value to the aircraft power system.
