Mobile Communication in Power Distribution Application

This paper investigates how to interface the wireless application protocol architecture to the SCADA system running distributed network protocol (DNP) in a power process plant, DNP is a welldeveloped protocol to be applied in the Supervisory Control and Data Acquisition (SCADA) system but the system control centre and Remote Terminal Units (RTUs) are presently connected through local area network The conditions in a process plant are harsh and the site is remote. Resources for data communication are difficult to obtain under these conditions, thus, a wireless channel communication through a mobile phone is practical and efficient in a process plant environments. Since the mobile communication industries and the public have a strong interest in the WAP technology application in mobile phone network and the WAP Application Programming Interface (API) in power industry applications is one of the area requires extensive investigation.
