StreetlightingBeijing sees the light with AmplightThe Beijing Capital HighwayDevelopment Company (BCHDC)concentrated on streetlightingwhen it was tasked with reducingcarbon emissions to meet Chineseemission reduction targets and managedto not only reduce energy use, but alsocut maintenance costs and improveservice.The company employed the AmplightEnterprise System, a centralisedstreetlight control system from Amplex.The system consists of modularcomponents and that allowed thecompany to configure Amplight to theclient’s needs.In Beijing, lights are now dimmedthroughout the night, returning to fullvoltage as the morning rush hourbegins. The system has allowed BCHDCto achieve 28 per cent energy savings.“The control and monitoring system isvery practical and easy to operate,”project manager Wang Desen said.“Our original target was 25 per cent,so we are pleased that we could exceedthis>’The system gave the company’smanagers detailed overviews of thecontrol cabinets, simplifying andaccelerating the process of detectingfaults and power leaks.An AmpLight solution is a completeweb-based server solution withadvanced communication design andeasy integration to existing installations.A centralized solution is easy toimplement and requires less equipmentand fewer manhours than a pole-basedsolution. The solution features:➔ Central control➔ Complete monitoring➔ Dimming➔ Remote metering➔ Power quality metering➔ Voltage stabilization➔ Control room installation.The system combines lowered costs andless emission without compromisingquality and safety. Energy and costsavings result from:➔ Dimming at off-peak traffic hours➔ Reduced maintenance costs➔ Burn hour optimizationA turnkey AmpLight solution enablesdetection of significant errors in thecontrol cabinetsand provides energy savings of up to35 per cent. Key advantages of acentralized solutioninclude:➔ Control cabinet fault monitoring➔ Automated reading of digital powermeters in control cabinets➔ Burn hour reports for proactive bulbchange➔ High up-time and immediate faultrectification➔ One central photocell ensuringuniformity➔ Improved quality of light➔ Simplified maintenance➔ Real-time control➔ Load balancing➔ Area-specific settings➔ Fast reaction to special traffic orweather conditionsAmplex has also designed a specializedcontrol room installation, where theclient gets full overview of AmpLight andany related systems. Projectors form aseamless widescreen image of the entiregeographic area at the backwall, wherethe operators monitor the streetlight anddispatch maintenance teams. Any alarmsand their exact location are shown onthe map for easy and fast overview.Amplex is a world leader in intelligentmonitoring and control of low-voltagepower grids, streetlight systems,metering networks and waterdistribution services.The company’s solutions helpmunicipalities and utilities all over theworld to intelligently monitor andcontrol their infrastructure assets so theycan minimize waste, save energy,streamline operations and improveresponse to demand.New ZEALAND LOCAL GOVERNMENT - SEPTEMBER 2009 23
