The present invention discloses a method for measuring the operating state of a synchronous motor using composite power angle meter.1t includes the following steps: a, obtaining all kinds of signals of the synchronous motor as well as the system; b, converting the electric signals described above into digital signals by data collection part in the composite power angle meter and inputting all the digital signals to a host computer; c, inputting related parameters or commands to the host computer by using the keyboard and mouse; d, the host computer calculating the motor's related data according to a program, obtaining the coordinates of related points as well as related data, and inputting the results to a image displaying program; e, by using the coordinates of main points and the calculated results, the host computer displaying graphs on the display by the processing of the image displaying program, the graphs showing dynamic composite power angle and compound leakage magnetism in the motor's end which change along with the change in the motor's parameters. The method supplied by the present invention can reflect the operating state of the synchronous motor directly from electric and mechanic aspects, and reflect the situation of the compound leakage magnetism in the synchronous motor's end. |
