Research On Building Electrical Energy Saving

At present,all countries in the world have the energy shortage and environmental pollution problems,the outbreak of the energy crisis forcing countries to formulate corresponding measures.In our country,the building energy consumption occupies a large part of the proportion of building energy saving,so it becomes an urgent problem.The electrical energy is an important part of building energy saving,therefore this article on the issue of building energy conservation in detail.In this paper,the construction of electrical transformers,power cables,lighting lamps,electric motors for the research object,the theoretical analysis,and on this basis summed up the effective way of energy saving.In based on the analysis of transformer of the main technical parameters,power loss,formulated the energy saving scheme of transformer;according to the type of lighting,way,lighting layout,and energy saving approaches in detail;analysis of the conditions for the selection of line and method for reducing the line loss;motor selection and characteristics are summarized,further demonstrates the its application in energy saving.At the same time,the detection method of instantaneous reactive power is introduced.Using the Matlab/Simulink tool to detect the harmonic current passive filter,P-Q detection method and ip-iq detection of three methods for modeling and simulation.Secondly,with the world attention to the new energy,combined with the actual life,this paper introduced photovoltaic power generation system,scheme is put forward according to the PV design software PVSyst,find information,according to the actual situation of underground shopping malls supermarkets photovoltaic lighting power supply system for the design and simulation,get the generating capacity of the simulation results.The comprehensive building in Songyuan City children's Hospital on,will the energy-saving theory scheme and photovoltaic power generation technology is applied to engineering practice,before and after the optimization of energy consumption was carried out in this regard,not only to meet the design requirements,while also reducing the energy consumption.
