There are many activities involved in creating lively, safe and comfortable spaces in the city. Similar to well-arranged pavements, good roads, and other accessible amenities, an important part of all public spaces includes lighting as well. It is, in fact, one of the primary aspects of urban planning. Good city lighting contributes to increasing safety alongside with being one of the primary factors in city transformation.
Over the course of the last few decades, the planning and design of lighting have changed. Bringing forth the transformation from road lighting to lighting focusing more on pedestrians, which includes parks and other public spaces. All these factors led to increased energy consumption and an increase in the overall lighting system complexity, which in turn created demand for more sophisticated lighting control system.
Belgrade’s public lighting company “Javno osvetljenje” operates a relatively old system which is getting harder to maintain and run with the increased demand for lighting monitoring and control. The system is unable to detect breakdowns or to notify operators in the headquarters if something goes wrong alongside a specific corridor, boulevard, park, playground areas, etc. Information about malfunctions is often received by citizens phone calls, and fixing problems involves sending maintenance units to places where the malfunctions occurred. This requires additional manpower and higher expenses for such a public service they provide. Since “Javno osvetljenje” does not generate profit, they decided to try to cut on expenses, therefore searched for a system that can be used both for monitoring and control of the public lighting.
Netico developed a modern light control sensor NTLC (Netico Light Control) and together with “Javna rasveta” Belgrade implement a pilot project, targeted following:
• High reliability • Two independent control outputs for turning the light On/Off (automatically, manually, and remotely, by bypassing calendar) • Light control operations (in default mode) operating by two independent calendars • Each calendar is configurable with the 1-minute time resolution • The system is also configurable remotely, using 3G or 4G mobile network • Different remote monitoring and control capabilities • Provides power quality indicators as per the Regulatory Agency’s requirements
NTLC by Netico was the perfect solution for the project. Since it is an industrial grade device capable of performing all the above requests, the system for public lightning monitoring and control provides the following features as well:
• Analyze network capabilities for three phases, records variety of energy parameters (voltage, current, power, etc.), store these for 5 years internally via SD card (8GB), additionally all of these can be access online, via web browser • NTLC’s web server is used for the system configuration or monitoring, via user-friendly web interface • System sends events to the selected IP address of an event server (which comes with NTLC) • It’s rule engine, a powerful tool for automatic monitoring and control, sends events, manage outputs etc., in case any of the predetermined logical operations are fulfilled (current is lower than threshold value, output relay is on but current is zero, etc.). It is used for detection of the burned out light bulbs.
Netico successfully fulfilled all project demands by installing monitoring and control system based on NTLC in the part of the recently reconstructed Vojvode Stepe boulevard, one of the longest ones in Belgrade. The system is connected on event server and verified system functionality. Netico also provided all the trainings and support needed, so “Javno osvetljenje” can independently run the system as per their policy. The system is periodically analyzed both by “Javno osvetljenje” and Netico over the course of two and a half years to verify its reliability, with no issues recorded.
