摘要：Aim at large aircraft power supply which use variable frequency ac power supply and has complex power system structure, the parameters test system needs to store the large amount of data, puts forward a data storage strategy based on the system time; To meet the testing requirements of voltage phase difference, three-phase voltage unbalance and other characteristic parameters, the article designs a measuring way behind on equipment synchronization trigger; Chooses the root mean square method as a means of voltage effective value calculation and analyzes the relationships about the calculation method between each cycle of sampling points and the relative error; Based on multi-channel measurement equivalent model of establishing the multiplexing card, analyzes the causes of errors in signal acquisition and put forward the solutions; Finally, testing on voltage parameters of a certain aircraft variable frequency ac power system, the test results show that the system is stable and reliable, it has reached the design requirements.
