Research On Power Supply Mode Of Tower Elevator Based On Abandoned Wind Power

The rapid development of the wind power industry promotes the development and utilization of renewable energy,and the fan is widely connected with electricity.The system,however,has a large amount of wind power that cannot be connected to the network,and there is a serious problem of abandoning wind,which causes huge energy waste and economic loss.At present,there are two main ways to solve the problem of abandoning wind power,one is to use energy storage to adjust the external consumption of wind power,and the other is the internal consumption of wind power plant.Wind fan in the daily maintenance,mainly rely on the inspection personnel climbing assignments to complete,this gives wind fan daily maintenance and troubleshooting the inconvenience,at the same time,increased security hidden danger and accident risk.However,the problem facing the elevator in the fan tower is that the power consumption of the wind farm will increase.Therefore,this paper combines the concept of wind power consumption with the concept of wind power consumption and elevator power consumption,and proposes a method to solve the power consumption problem of the fan tower drum by using the wind power.The main contents of the paper are as follows:Firstly,the matching relationship between real-time wind abandonment forecast and real-time elevator power consumption under daily maintenance plan is analyzed.Coordination control strategy of wind abandonment and energy storage is formulated based on real-time wind abandonment and real-time elevator power consumption and energy storage allocation.Secondly,in the analysis and calculation of the actual quality parameters of components of multi-rope friction hoisting system,the dimensionless method is adopted to select reasonable reference value,and the car weight,wire rope weight and car weight are obtained by satisfying static tension ratio and anti-skid criterion.The safety evaluation model of tower elevator is established,and the primary investment cost of tower elevator and energy storage and the abandoned wind power are taken into account.The economic evaluation model is established based on conversion value,dimensionless elevator investment cost and energy-saving operation cost,introduction of tower elevator to reduce the conversion value of personnel input,and conversion value of tower elevator power consumption.Finally,the feasibility of the combined power supply mode of wind abandonment and energy storage is demonstrated and simulated with MATLAB.
