2、utonomous Organ of the Institution of Engineers(India),NEED OF THE HOUR,Distribution system forms the ultimate link in the power system between the utility and end user.Customer expectations also have gone up to provide,Reliable and quality power,Timely redressal of complaints,Accurate metering and

3、billing without errors,Facility&Flexibility of payment of bills from home,NEED OF THE HOUR,Many more in the wish list,This can be only possible if the human element at work is replaced to a good extent by automating the operations and use of Information technology becomes indispensable at this junct

4、ure,What do we need to do to meet the expectations,Replace still old,conventional,manual systems being continued in most of discoms,With the growth of network and the number of customers adopt newer technologies that provide faster service,NEED OF THE HOUR,Where human intervention is unable to cope

5、up,adopt automation using the available&powerful IT tools,The end result should be that customers are to be provided service levels like in other sectors like banking,communications etc.,All these would improve the image of the utility,NEED OF THE HOUR,The focus areas of IT applications are,Quality

6、and reliability of supply,Accurate of billing,Easy payment mechanisms,Better complaints handling,IT is used in energy audit,Estimation of baseline losses&,Substation/Distribution automation,AREAS OF FOCUS,IT INITIATIVES,Aims at,Improvement of efficiency by way of elimination of delays,duplication,dr

7、udgery in paperwork,Reduction in overall expenditure.,Provides quick and efficient information systems like on line billing,collection and on line report generation.,Very fast reconciliation between important activities of metering,billing and collection.,Web based servicing.,To attain transparency

8、and gain credibility.,Customer satisfaction.,New Trends,Automated Meter Reading,Web Based Servicing,Trouble Call Management System,SCADA,Consumer Analysis Tool(CAT),IT IMPLEMENTATION INITIATIVES,IT in System Planning,Load forecast is an important parameter for system planning,Requires accurate data

9、of the system like energy consumption for last 10 years,maximum demand,Methods of load forecast,Trends:The trends for the growth in energy and consumption are computed based on the past data are,To forecast the future demand/energy,IT IN SYSTEM PLANNING,Econometric Approach:,Focuses on identificatio

10、n of correlation between demand and variables such as growth in GDP,population and households in the forecast,End-use Approach:Focuses on uses of electricity,takes into account specific consumption of major appliances,degree of saturation of each appliance per customer,number of customer,Using the l

11、oad forecast developed using appropriate models,appropriate system planning package is to be selected for running the load flows,IT IN SYSTEM PLANNING,SCADA:Supervisory Control And Data Acquisition,It is a system that enables an electric utility to remotely monitor,coordinate and operate distributio

12、n components in a real time from remote location.,IT IN SYSTEM OPERATION,The basic components of SCADA system are,Control center,Controlled plant,Communication system,SCADA platform uses a master slave communication principle and controls the remote end equipment through Remote Terminal Unit,IT IN S

13、YSTEM OPERATION,RTU can perform several functions like data acquisition,switching of circuit breakers/capacitors,changing of taps etc.based on the commands received from the control centre.,IT IN SYSTEM OPERATION,In the later versions of SCADA,RTUs are being replaced with IEDs(Intelligent Electronic

14、 Devices),which have the capability of measuring,monitoring,control,protection and communicating to the local operator or to the remote host,(Ex:Numerical Relays),IT IN SYSTEM OPERATION,We can build a Distribution Automation system using the SCADA kernel which can accomplish many functions such as:,

15、Substation Automation,Feeder monitoring and control,Load Management,Automated Meter reading,Trouble call management,Load Survey&Energy audit and so on,IT IN SYSTEM OPERATION,Feeder Monitoring and Control,Trippings and breakdowns in general and in rural areas in particular is a matter of serious conc

16、ern which causes prolonged interruptions and consumer unrest and the same can be addressed through feeder monitoring,Automation of the feeder control can be taken up using Auto reclosures near the breakers and sectionalisers in the line,IT IN SYSTEM OPERATION,Feeder Monitoring and Control,For any transient fault in the line,the auto reclosure first trips and then closes after a set time,Sectionalisers help us in isolating the fault during permanent faults and the supply can be restored for the r
