Application Research Of Wind Tuebine In Data Center

The main content of this paper is the application of wind turbine in the raised-floor data center.The internal load of data center is dynamic.At the same time,the internal equipment is updated irregularly,and in some Case the internal design of data center is unreasonable,so most of the cooling schemes used in raised-floor data centers are relatively conservative,which leads to an excessive supply of air-conditioning in data center.In this Case,to solve the problem of energy inefficiency in a data center caused by the excessive supply air in the data center,the wind turbine is introduced into the data center.The excessive wind energy is used to drive the wind turbine to work and the electricity generated by the wind turbine can be stored in some power storage devices and supply to the data center to fit the consumption.Energy efficiency has been improved in the data centers.The research of this paper mainly proceeds from the following aspects:(1)Firstly,using computational fluid dynamics(CFD)method,the effects of the parameters of wind turbine on the power of the wind turbines,the flow of CRAC in the data center,the flow of static pressure box under the floor,the flow at perforated tiles and the inlet temperature of cabinet in data center are discussed.Through the existing experience-based thermal environment index,the thermal environment of the data center with and without the wind turbine is analyzed.A simplified flow damping model is established based on the Betz’s theory in the modeling process of wind turbines.In this research,it is found that under the condition of properly setting of wind turbine parameters,the addition of wind turbine would not have a negative impact on the thermal environment of data center.On the contrary,the selection of some specific parameters may be helpful to improve the utilization efficiency of cold air in data center,which shows the feasibility of introducing wind turbine into data center.Sex.(2)Then,in order to optimize the parameters of the wind turbine,the entransy loss of each heat transfer process in the data center is derived on the basis of the entransy theory.According to the entransy loss of each heat transfer process,the variance analysis method is used to optimize the wind turbine in the data center.By optimizing the wind turbine,the deterioration of the internal thermal environment of the data center can be reduced to a minimum extent,and it is found that the working interval under the influence of wind turbine on the thermal environment of the data center is also the working interval where wind turbine works well.(3)Finally,in order to meet the practical application of the project,the control system of the wind turbine system in the data center was studied.In the design of wind turbine control system,fuzzy control method is introduced,and the design of fuzzy controller is studied with MATLAB.After studying the design of the fuzzy controller,the neural network is introduced into the design of the controller to improve the fuzzy controller.The completed fuzzy controller can basically meet the requirements of the control system.
