  1. The Importance of Remote Monitoring in the Management of Energy Efficient Telecom Cell Sites Michael Ukabam Head, Innovation and Systems Integration Bangkok, 25th May 2012

  2. Why Remote Monitoring System?? • Network Management • BTS site Status • BTS site history • Disaster Management • Site Management • Maintenance Scheduling • Effective Resource allocation • Equipment performance history • Failure Management • Early fault identification • Site up status and nature of faults • Remote Intervention • Equipment Evaluation • Site Battery condition • DG battery condition • Site temperature • Billing • Diesel Supplies • Grid consumption

  3. Scope of a Remote Monitoring System • Basic Information • Detailed Parameter Monitoring • Integration into sub Systems • Full monitoring and control

  4. Value proposition for remote monitoring systems • Early warning of fault condition • Detailed data to understand failure mode • Early and accurate mobilization of resources • Increased Network uptime • Automated accurate fuel deliveries • Alerts sent for abnormal consumption • Improved resource utilization • Reduced opex • Reduced cost of management resources • Benchmarking of site performance • Centralized accurate billing • Centralised Network Management • Disaster management • Equipment performance optimization • Continuous improvement • Real time visibility of critical parameters

  5. System Architecture

  6. Components

  7. Central Console view • High level colour coded view of sites • Unlimited number of sites only limited to screen size • Enter individual icon for more details

  8. Detailed View The Site Details Status tab shows the current status of various monitored devices Each monitored device shows the date & time since the last change of status together with its current status

  9. Detailed View Power Management Enabled or Disabled from here. If Enabled the Power Management system will conserve Generator running time when there is no Mains Power available. The system may also be over-ridden to force to BTS Batteries or Generator power source. The Pie chart shows an overview of Site running time on the various power sources available.

  10. Detailed View A major priority fault such as a “BTS Batteries Critically Low” alarm would invoke a flashing red icon on the Console screen A medium priority alert of Low Fuel would invoke a flashing icon with “Low Fuel” superimposed on it. A low priority alert such as “Fuel Sensor Disconnected” would invoke a flashing icon with a red question mark superimposed on it

  11. Detailed View • Diagnostics • DG Reset • DG Test • System Reset

  12. Detailed View The Activity Log is a full history of all Faults and Alerts and Information received from the remote BTS site. It also logs all activities from users of the Mobile function, logging their Name and their Activity together with the date & time of the event.

  13. Fuel Monitoring Fuel Theft Fuel Deliveries

  14. Mobile Monitoring • Real-time Monitoring & Enquiries • Check status of any monitored Site • Is Generator(s) running ? , Is Generator Contactor In ? • BTS Battery voltage • BTS / Transmission Battery Charge / Discharge Current • BTS container internal temperature • Generator Fuel Level (in litres) • Is Generator Common Alarm Active • Perform functions on Gen-Set • RESET AMF panel from temporary fault and re-start generator • Force Generator to stop and enter Battery Mode • Force Generator to Start and enter Generator Mode • Force Temporary Mains Failure to test generator will start • Secure & Safe • Only mobile numbers registered in the system have access • All commands are passive or time-out fail-safe

  15. Orun Energy Hybrid System Overview

  16. DG • Cooling Standard Site Analysis • Fuel • Deliveries • Usage • AC Aircon • Surge start • Temp. Control • Solar loading • High Usage • Consumption • Sizing • BTS • PSOC • DOD • Cycle life • Charge rate • Charge curve • Temp tolerance • Site Status • Intervention • Visibility • Battery

  17. Integrated Energy Efficiency Approach SMS to Web Remote Monitoring *Temperature *Generator cycles *Fuel levels *Battery status* Site Control

  18. Power Source Brake-down 1OD • Single Out-Door GBT • Test Duration 10 Dec 2011 to 25 02 2011 (77 Days)

  19. Power Source Brake-down 1ID

  20. Usage Patterns (1ID)

  21. Sample Daily Printout (Indoor Site)

  22. Sample Daily Printout (Indoor Site)

  23. Test Savings Summary (1OD) Litres USD Opex Savings USD 6,300 / site /year Site uptime 100% $0.86 / litre $0.14 / Kwh

  24. Zero Capex: Off Grid Outdoor Site Full Component and System Warranties over 8 years
