A kind of substation commissioning panoramic surveillance system was realized through the 3G/4G communication network and deploying tunnel communication program in the cloud server to obtain real-time measuring waveform data,equipment state and the state of the task of multiple substations to achieve the purpose of panoramic debugging and monitoring. Also each substation measuring equipments receive the second synchronous signals of GPS Satellite to get time synchronized measurement waveform data, thus to get the time association of each substation measuring data. The test results show that the system has real-time and intuitive access to the site measured waveform, equipment status and the progress of the experiment of each substation. It realizes the panoramic monitoring of start debugging of multi substations.
