| Abstract: |
| In order to solve the problem of the inconvenience of a cross-interval phasor check in a substation, a method of cross-interval phasor check based on radio frequency communication technology is proposed for substations, aiming at the three different applications of cross-interval phasor check between analog and analog, digital and digital, as well as analog and digital. A specific implementation scheme is provided for the two key technologies of both wireless data transmission and sample synchronization. The hardware and software designs of the device are introduced. Corresponding phase compensation algorithms are designed for the different phasor checking applications. The device is used in the relevant test at the substation scene, and the test results are analyzed. The test results indicate that by adopting radio frequency communication, the device optimizes the traditional cross-interval phasor checking method, and the actual needs of a cross-interval phasor check under different applications in substation are also satisfied.
