Hydropower Plant Inspection System Based On Handheld Computer Technology Research

With the development of the automation of substation, the inspection of substation is becoming more important. In order to avoid the inadvertence of inspection tour and increase the data utilization ratio, a new portable inspection tour installation has been brought into service in this field. The inspection tour system adopts the bar code to identify the power equipment, collects the parameters with a pocket PC and then manages them by database. The system can analyze the operation tendency of equipment and displays the curves between any two parameters. The results can be browsed in the Web site. It is proved by practice that the inspection tour system can ensure the inspection tour be on time and on spot.This paper emphasizes the application of pocket PC technology in the inspection system. The palm with scanner is adopted as the inspection facility that can easily record equipment bug and run parameter. So inspection ratio will be improved availably. The significance of the system means improving of inspection efficiency and equipment's safety.
