1. Distribution Automation System (DAS)
Purpose of Distribution Automation 
System
Characteristics of distribution grid
•Widespread and complexly connected, thus difficult to acknowledge the emergency situation
•Natural disaster and operational mistakes are major causes of the fault.
•Failure and fault directly influence on the customers outage.

Reduction of outage time
Long outage time causes income decrease and negative effects to industrial 
economy.
FDIR: Fault Detection, Isolation and recovery
Utility’s personnel tries to detect the fault section, then restores 
manually.

Advanced Metering Infrastructure (AMI) is a broader concept than AMR.
AMI includes home display, Meter Data Management System (MDMS) in addition to AMR.
AMI can provide Demand Response (DR) Solution.
Smart Meter
Measures instantaneous values including power 
consumption, voltage, current, frequency and other 
data and sends values to the meter data 
management system and home displays.
Meter Data Management System
(MDMS)
Remote metering of data measured by the smart meter. 
Real time data collection, management and analysis.
Home Display
Displays electric energy used, 
electric energy sold, CO2 
emissions and other data 
measured by the smart meter.
