  3. CRITICAL SUCCESS FACTORS FOR UTILITY Maintain Reliable Power Supply Optimize Cost of Supply Regulatory Compliance Achieved by Proper Energy Billing and Accounting Proper Asset Management Proper Network Analysis & Planning With the help of Spatial Asset Information - GIS

  4. GIS Architecture

  5. Power Utility Applications in GIS • Network Analysis • Single Line Diagram (SLD) • Load Flow Analysis (Voltage drop/ Loading) • Contingency Analysis • Switching Optimization • Capacitor Placement • Reliability Analysis • Electrical Design Manager • Work Order Processing • SAG Calculation • BoQ preparation • Other • Energy Auditing • Asset Management

  6. INFORMATION IN GIS Information on Road

  7. Information on a Sub-station

  8. Information on a HV line

  9. Information on a Transformer

  10. Network Analysis Tools • The network Analysis is carried out by using – • The Network topology and data from IS • Computerized Analysis Tool • The Network tools available – • Cyme Dist • SYNERGEE • CALPOS • WIND MIL • NEPLAN • POWER (Hitachi) • POWERNET (Global)

  11. CYMEDIST • Primary Distribution System Analysis tool • Capability to perform several type of analysis like- • Balanced or unbalanced on three-phase • Two-phase and single-phase systems • All above with radial, looped or meshed configurations. • Voltage drop and power flow analysis. • Fault calculations • Optimal capacitor placement and sizing. • Load balancing • load allocation/estimation. • Switching Optimization • Reliability Analysis

  12. CYMEDIST REQUIREMENT • For Dedicated Users : • A PC with P-IV Processor • 20 Gb HDD • Minimum 128 MB RAM • 17” Color Monitor • Window-98 or higher • CYMEDIST Software CD • CYMEDIST Hardware License key • GIS Data File of Network • For Web Users in GIS: • PC with normal configuration • Web Browser • CYMEDIST Interface with GIS

  13. NETWORK ANALYSIS IN ‘CYME’ USING GIS DATA • GIS Core • Network Connectivity • Network Asset details Compatible Format- Dw/ mif DB Access Network data from GIS • CYME • Voltage Drop Analysis • Capacitor Placement • Short Circuit Analysis • Load Allocation • Service Restoration • Reliability Analysis • Contingency Analysis Network Analysis in GIS

  14. GIS - CYME INTERFACE • GIS Core • Network Connectivity • Network Asset details Access Cyme Algorithms DB • CYME • Voltage Drop Analysis • Capacitor Placement • Short Circuit Analysis • Load Allocation • Service Restoration • Reliability Analysis • Contingency Analysis Network Analysis in GIS

  15. CYMEDIST – Details and Demo • Network Modeling • Load Flow Analysis • Contingency Analysis • Tie Point Optimization • Reliability Analysis • Capacitor Placement

  16. Demo • Network Modeling • Import GIS Data • Modeling • Load flow Analysis: • Input the Loading Conditions • Find Voltage Drop in all elements • Find Loading (both active/ reactive loads) • Find Technical Losses • Contingency Analysis: • Study impact of Single Outage on the System • Find optimize Switching Plan to restore max. load

  17. Tie Point / Switching Optimization : • Help determining optimum feeder configuration to • minimize losses • Improve voltage regulation • Based on user defined thresholds- • Suggest Closing/ Opening of existing switches • Suggest addition of new switches • Reliability Analysis: • Run the scenario to the impact of Distribution Automation can be evaluated • The system indices such as SAIFI, SAIDI , ENS can be evaluated
