Green Lighting Design for 220 kV Xijing Intelligent Substation

Lighting design in 220 kV Xijing intelligent substation is optimized in accordance with the substation green lighting methods.Considering the layout of Xijing substation,LED is proposed to replace traditional light sources for energy saving in intelligent substation.Lighting distribution box is assembled in cabinet and laid in secondary equipment room to improve maintenance efficiency.Control switch is connected with auxiliary control system to realize automatic light control.The analysis results indicate that when intelligent substation uses indoor layout,the initial investment for green lighting is large,but can be recovered within short term owing to saving energy.It is also proposed that intelligent auxiliary control system adopt independent lighting distribution and control system.
