The invention relates to a
transformer substation starting test
wireless nuclear phase debugging method. The method includes the following steps: using a GPS /
Big dipper satellite to provide accurate absolute time to a
system, supplying a radiofrequency
wireless time
service module; the radiofrequency
wireless time
service module using second pulse of the GPS /
Big dipper to provide accurate time service pulse to different
data acquisition modules; each
data acquisition module acquiring a three-phase
voltage of a device under nuclear phase, and based on the time service pulse, conducting
time stamping on the acquired data, recording
generation time of the data, and real-time transmitting the data to a
data processing and analyzing terminal through wireless communication; the
data processing and analyzing terminal in according with the time when the data is received,
processing the data transmitted by the different
data acquisition modules, extracting a fundamental component and a phase of the data in different phases, finally displaying
data processing results through a display and control platform. According to the invention, the method addresses the problems of large amplitude difference of the device under nuclear phase, containing of
harmonic component, and screen cabinet. The method increases accuracy and reliability of work in
transformer substation starting nuclear phase debugging.
