Recently, the largest-scale DC-powered urban-level intelligent LED street lamp renovation project implemented by China Southern Power Grid Integrated Energy Co., Ltd. (hereinafter referred to as South Net Energy Company) completed the acceptance inspection of the LED street lamp energy-saving renovation project in Zhaoqing High-tech Zone. A total of 5,722 LED street lights were installed in the project. After third-party energy conservation assessment, the project's power saving rate reached 66, saving electricity of 4.95 million kWh per year, equivalent to saving 1,700 tons of standard coal, reducing carbon dioxide emissions by 4,690 tons, and reducing lighting load by 1,354 kW. The annual electricity cost is 4.06 million yuan. The road surface illumination is improved after the renovation. 26. The project adopts the contract energy management mode. The South Net Energy Company is responsible for all capital investment, construction, management and service. The energy-saving benefit sharing period is 9 years, and the saved electricity costs are based on the owner 15 and the South Network Energy Company 85. The proportion is assigned. The DC centralized power supply and intelligent control system built by the project integrates various technologies such as cloud platform, IoT perception, control and data processing. Through the intelligent control system, various functions such as dimming control can be realized, and the mobile terminal can also be used. The remote monitoring of the lamps and lanterns truly realizes the intelligent and refined management of the lighting system, greatly prolongs the service life of the lamps and systems, improves the stability of the system, realizes the secondary energy saving of more than 20, and greatly reduces the maintenance cost of the street lamp system.
