AUTOMATION Improved Efficiency Increased service reliability WHY Flexible control Effective utilization of assets Service Continuity 2

DISTRIBUTION AUTOMATION IEEE Definition: ‘‘A system that enables an electric utility to remotely monitor, coordinate, and operate distribution components in a real-time mode from remote locations. ’’ v. The concept of distribution automation first came into existence in 1970’s 3

SCADA SYSTEMS Commonly used in generation & transmission systems Monitors metered and status data Operator’s aid It is an open-loop control system. 4

SCADA Human Machine Interface (HMI) Supervisory (computer) system Remote terminal unit (RTUs) Programmable logical controller (PLCs) 5

Typical SCADA system Automated Distribution Systems 7

System level functions of Distributed Automation v. Transformer Load Balancing v. Capacitor Bank Switching v. Fault Isolation and Sectionalizing v. Voltage Regulation v. Voltage Monitoring 7

Consumer level functions of Distributed Automation v. Automatic Meter Reading (AMR) v. Demand Side Management (DSM) v. Load Management v. Quality of Service (Qo. S) Monitoring 8

AMR ØAutomatic Remote Meter Reading ØAutomating the process of measurement through digital communication techniques. ØBring “intelligence” into the revenue cycle and manage it: Metering Billing Operations Customer Service 9

AMR Simulink model

Critical Benefits from AMRs n Ability to detect tamper events and outage occurrences. n Remotely Connect/ Disconnect power supply through meter. n 15 minute interval data gives accurate load information for supply scheduling, switching operations, planning etc n Monitor voltage at each premise to know conditions when to operate capacitor switches or regulators n Consistent and data for improved accuracy
