Application Research On Building Electrical Energy Saving Design

Shortage of energy resources is an important problem facing our country and around the world,on our hand,improving energy efficiency and saving energy is an important way to affect the continuous and stable development of economy in our country.In our country,building energy consumption accounts for about a third of the country’s energy consumption,the energy consumption of the first place,and main part to save energy is to save from building electricity so electric energy saving is of great urgency.Building energy waste is very serious in our country,whether it’s power supply and distribution system,lighting system,building electrical equipment,there is a large energy saving potential.Based on each link of electrical system of building energy consumption analysis,the power supply and distribution system,lighting system,and construction equipment in energy and photovoltaic power generation systems and other four content as the research focus,research purpose is to satisfy the building electric and perfect the building use under the premise of functional requirements,reduce energy consumption,improve energy efficiency.In this paper,the main research contents include:Firstly,power supply and distribution system,the analysis of the system harmonic,power factor and the harm of three-phase imbalance,on the basis,mainly is improve the PF parameter and change the three harmonic measures were studied,to improve the power supply and distribution system design,reduce the loss of power grid,improve power supply quality.Secondly,energy-saving lighting system,based on the illumination energy conservation evaluation indexes,through the comparative analysis of lighting equipment,the energy saving of lighting control,through the reasonable design,improving the quality of lighting,save power.Thirdly,building energy-saving equipment,mainly for transformer,motor,elevator energy consumption are analyzed,studied the energy saving measures of construction equipment,and has carried on the thorough discussion to intelligent control of construction equipment,through reasonable control,design,scheduling,reduce building energy consumption.Photovoltaic power generation systems.Forthly based on the principle and composition of photovoltaic power generation system were analyzed,and the design process of photovoltaic power generation system is discussed,the research determine the method of the solar cell phalanx and battery scale,including the safety and reliability requirements.
