PLC-Based Street Lighting Energy-Saving Equipment and its Remote Monitoring System

Abstract:

PLC (programmable logic controller)-based street lighting energy-saving and remote monitoring system is designed to improve energy-saving technology and management level. The designed illumination economizer contains PLC-based controller unit and compensating transformer unit, which can realize closed-loop voltage control at the stage of voltage stabilization, and reduce the negative influence of power line voltage fluctuation upon lamp service life and visual luminance. On the basis of the illumination economizer, a GPRS-based street light remote monitoring and control system is designed with configuration software. The whole system has been operating reliably in Harbin, China for many years with an over 50% energy-saving rate, decreasing the illumination management cost and promoting the intelligent management level.
