Development of a generalized database for power system network of Bangladesh with reference to supervosory control and data acquisiton (SCADA)

Abstract

An electric power system network contains generation, transmission and distribution of power. There are number of authorities involved with power system and everyone maintains its own system and there is no consistency with each other. To address this problem a generalized database is designed considering aforementioned three components. Two databases are designed one local database for substation where data is directly collected from the EMS (Energy Measurement System). And another central database for SCADA (Supervisory Control and Data Acquisition) center where data is sent (collected) continuously from remote substations. Proposed system uses EDGE (Enhanced Data rates for GSM Evolution) or DSL (Digital Subscriber Line) network technology for sending data from remote terminal unit to SCADA center. Developed database has been implemented for power utility company DES CO. Finally a set of reports format have been designed from both RTU (Remote Terminal Unit) and MTU (Master Terminal Unit) perspectives.
