A method for LED lamp life increased 5 times

According to Nanfang Daily reported that the 16 day was informed by the Guangzhou Power Supply Bureau substation management two and South network energy company, the joint implementation of the whole network first green lighting intelligent substation in Guangzhou Luo Yong 220 thousand volt substation. The project has the lighting industry Oscar said the "2015 Aladdin" Award (Engineering)".

The original project 965 old indoor and outdoor lamps are replaced for energy-efficient LED lights substation customization, and the use of intelligent lighting control system of HVDC centralized power supply based on the illumination data acquisition, real-time monitoring and intelligent dimming and other advanced features.

South Network's first green lighting intelligent substation

Guangzhou Power Supply Bureau Luo Yong substation is one of the main substation in Guangzhou area, since the 2010 lighting update, substation lighting system gradually aging damage, high energy consumption, maintenance operation workload, lighting quality can not meet the demand of substation work situation.

In order to change the lighting system, behind the old station fundamentally since September 2014, Guangzhou Power Supply Bureau substation two UN south network energy company, full transformation substation lighting system startup. The project team developed a "lamp, lamp pole, a driving power supply, intelligent control system, professional lighting design modeling" series of products, the amount of customized "five in one substation green professional lighting solutions" to help the substation to achieve a "green upgrade".

Guangzhou existing 300 substations will transform

From September 2014 onwards, the project team spent 3 months, completed the transformation of the green Luo Yong substation, LED lamp station 70 of the original traditional outdoor lighting lamp lamp and 895 indoor lamps are replaced with high efficiency and energy saving, and the use of intelligent lighting control system for high-voltage DC centralized power supply.

After the transformation, the regional average illuminance of substation substantially increased by 7 times (from the previous 1-5 to 23-148 lux Lux), the lighting power consumption from the previous year 163 thousand kwh dropped to 33 thousand kwh, power plant lighting power fell from 4.4718 kilowatts to 1.7394 kilowatts, lighting power decreased by 61.1%, and through the intelligent control of light at two energy-saving, comprehensive energy saving rate up to 80%. By running 10 hours a day, a year can save electricity 130 thousand kwh, an annual reduction of about 90 thousand yuan electricity.

After the transformation, LED lamp life increased 5 times, up to 50000 hours or more, since the lighting equipment failure rate 5 months from 30% down to 0%, can save maintenance costs 16 thousand yuan per year.

It is understood that the present Guangzhou area a total of 300 substations, 500 thousand volt substation 6, 220 thousand volt substation 49, 110 thousand volt 245, the annual lighting power consumption were 40, 20 and 100 thousand kwh, such as the implementation of all LED green energy saving, will bring considerable energy saving and economic benefits: the equivalent of 25 thousand tons of carbon dioxide emissions per year, with 10 thousand tons of standard coal, equivalent to planting 40 thousand, to reduce annual lighting costs 25 million yuan for Guangzhou power supply bureau.

According to the Guangzhou power supply bureau "13th Five-Year" plan, Guangzhou Power Supply Bureau will be combined with the construction of the 3C green substation and four savings and environmental protection work, study in the new substation and the existing substation in the comprehensive promotion of green intelligent lighting solutions.
