Research On The Cabin Environment Intelligent Control System Of Wind Turbine

With the rapid development of the global wind energy,the world of new energy demand continues to increase,the number of running wind turbine is increasing,with the deterioration of the wind machine long time running and the fan operation environment,the unit components will inevitably happen destructive accidents.Because most of the wind farms are in bad environment,the wind blowing dust,haze serious influence,spring catkins sky,summer temperatures and other factors,led to the fan cabin,gearbox fin pollution,dust clogging cooling system of air intake,resulting in a decline in the performance of gearbox heat changer,causes the wind turbine gearbox oil high temperature,fan power limit and even stop working.In particular,a serious impact on the power output of the wind farm in the spring and summer catkins pollution high period,must spend a lot of manpower for processing,the traditional method of artificial dust,which greatly increases the maintenance staff,because the maintenance effectiveness and delay fault judgment factors,the increase of wind turbine is not available hours,causing economic losses of the wind farm.Therefore,it is necessary to develop a highly effective and diversified intelligent control system for wind power generation units,which can simultaneously monitor and deal with wind power problems.In this context,the intelligent control system of engine cabin environment is studied in this paper.First of all,the main heat source on the unit inside the cabin are summarized and analyzed,get the causes of fever of each part of the heat source,and compared the advantages and disadvantages of existing solving measures,and provides exact data for the the location selection of the temperature sensor diagnostic system.Based on the finite element analysis software and CFD and numerical heat transfer,in this paper discussed the feasibility of the method to simulate the internal temperature of the cabin,and describes the gear bearing lubricating oil heat,heat generation,heat generation and simulation of gearbox,introduces the calculating method of the gearbox.The research provides the foundation for further study.Secondly,this paper presents the hardware design of the control system,through comparing different types of fan characteristics,choose suitable fan shaft inside the cabin,summed up the main conditions to consider ventilation components,and puts forward the selection of axial flow fan heat fan demand.In this paper,mainly discussed the selection offilter material and compared of the characteristics of four commonly used filter nets.According to the results of simulation algorithm applied in the existing literature,choose the most suitable and commonly used filter screen materials for fan cabin environment.Last,this paper analyzed the functional requirements of the cabin intelligent control system,and selects and studies suitable algorithm of the stepper motor control system.By tuning the expert self-adaptive PID parameters and judging by the algorithm,the stepper motor can be operated and controlled,and realized the air supply of cabin and the intelligent filtering system automatic replacement.Through the comparative analysis of the output power and the internal gear box temperature curve of the three groups of prototype,the conclusion is drawn that the intelligent control system of the cabin environment plays a significant role in improving the operation and efficiency of the fan,and it can solve the existing problems in the fan cabin environment.It provides a solid theoretical basis for the future prospect of this study.
