Wind Power Turbine and Its Aerodynamic Characteristics

By Xianyi Qian Yiming He

DOI: https://doi.org/10.5815/ijeme.2012.07.11, Pub. Date: 29 Jul. 2012

We have mainly studied wind power turbine’s aerodynamic characteristics in this paper. We first introduced the types of wind power turbines, and then analyzed the force on the vanes which caused by air flow. We also studied the geometry shape of vanes’ type and its aerodynamic characteristics. At last, we concluded the corresponding formulas about wind power turbine’s aerodynamic characteristics. All what we have studied have important role to design wind power turbine’s vanes.

Power Factor Analysis of the Linear Motor in Mines

By Xianyi Qian

DOI: https://doi.org/10.5815/ijwmt.2011.01.04, Pub. Date: 15 Feb. 2011

This paper introduces the structure of linear motor in mines. Analyze the power relation of power-AC -linear motor – vibrant machine, based on this, count the power factor; and make mechanical analysis to the vibrancy, get the power factor, which should be: in the precondition of without collision for the top and bottom magnet, do best to decrease the δ_0 to close to ΔΧ_m (ΔΧ_m depends on the technique of the vibrant load), make Κ_δ close to 1 and λ_e close to critical maximum λ_(em) . It is significantly useful to design linear motor.

Structure and Control of Flywheel Energy Converter

By Yiming He Xianyi Qian

DOI: https://doi.org/10.5815/ijwmt.2011.01.06, Pub. Date: 15 Feb. 2011

On the basis of the flywheel energy converter’s structure in wind power turbine, we have used permanent-magnet synchronism motor as energy converter and built mathematical model. We have studied and realized control method of wind power turbine’s constant output power. By analyzing the mathematical model, we have concluded that the needed time of stored energy is three times longer than constant torque control time, and the needed motor power is one second of constant torque control. When flywheel starts from zero speed to basic speed ([(ω_max)/5]), the constant torque control method will be acquired. When flywheel speeds up between [(ω_max)/5] and ω_max , the amplitude power control will be acquired. What we have studied is very important to realize constant output power.

Electromagnetic Field of Resonance Linear Motion Actuator and its Finite Element Analysis which Applied to Coal Mine

By Xianyi Qian Yiming He

DOI: https://doi.org/10.5815/ijem.2011.01.01, Pub. Date: 8 Feb. 2011

In this paper, we have introduced the structure of resonance linear motion actuator which applied to coal mine. And we have built two-dimensional analyzing model by using finite element method. On the basis of the analysis, we have calculated the motor’s air-gap field and magnetism, and we also have studied the affection of motor which caused by permanent magnet’s size. We have studied motor’s winding current when it operates at constant amplitude, and the corresponding experiment results have verified the correctness of finite element model. We have studied the numerical value calculation of resonance linear motion actuator and calculation of its magnetism characteristic. What we have analyzed shows that the air-gap field of motor changes continuously and the magnetism is proportional to winding current. And the results can help technologists to design this kind of motor.
