The invention discloses an aviation ground inverter power characteristic test system and observing and controlling method. The aviation ground inverter power characteristic test system comprises a three-phase large-power program control load, a voltage current signal processing circuit, a data acquisition card and a computer. An A input end, a B input end, a C input end and a N phase input end of the three-phase large-power program control load are respectively connected with an A phase, a B phase, a C phase and a N wire of the aviation ground inverter power. An A input end, B input end, C input end and N phase input end of the voltage current signal processing circuit are respectively connected with the A phase, the B phase, the C phase and the N wire of the aviation ground inverter power, and an output end of the aviation ground inverter power is connected with an input end of the data acquisition card. An output end of the data acquisition card is connected with the computer. The computer is connected with the three-phase large-power program control load through serial ports. The aviation ground inverter power characteristic test system can not only meet the aviation ground inverter power characteristic test requests to the international standard international standardization organization (ISO) 6858 and the civil aviation administration of China MH / T 6018, and but also be provided with the function of analyzing and assessing. And the system structure is arranged to reasonable, and the observing and controlling method is simple. The operation is convenient to do, and the measurement accuracy is high.
Description
technical field [0001] The invention belongs to the technical field of electrical measurement, and in particular relates to a characteristic testing system and a measurement and control method of an aviation ground inverter power supply. Background technique [0002] The aviation ground inverter power supply is to convert the 220 / 380V, 50Hz mains power on the ground into a 115 / 200V, 400Hz power supply that meets the power supply requirements of the aircraft, and is used to supply power to the aircraft when it is on the ground. Since the electrical equipment on the aircraft has strict requirements on the power supply quality of the power supply system, and the ground power supply of civil aviation airports must supply power to aircraft of domestic and foreign airlines, the ground power supply must comply with the ISO6858 international standard, and at the same time comply with the MH of my country's civil aviation. / T6018 Aircraft Ground Static Power Supply Industry Standard. ...
