Embodiment 1

[0028] 2X1,600kW stand-alone power generation device, the 2 sets of generator sets have the same settings:

[0029] The diameter of wind turbine 2 is 2M, the thickness is 0.4M, the rated speed is 300rpm, and the weight is 300kg. According to the formula of moment of inertia: J=(m*r) / 2=(kg*r*r) / 2=(kg.m2), m-weight, r-radius, 300*1*1 / 2=150kg.m2, according to the torque formula: T=J*V / R=N.m, V-line speed v-3.14. diameter. speed / 60=3.14 *D*n / 60(m / s), r-radius of rotation, then the wind turbine main shaft 22 torque T=150(3.14*2*300 / 60) / 0.9=5,233N.m.

[0030] The rated rotational speed of the auxiliary drive motor 5 is 300rpm, and the rated power is 200kW. According to the calculation formula of torque, power and rotational speed: T=9,550P / N (T is Nm, 9,550 is a coefficient, P is kW, and N is rpm): Moment T=9,550X200 / 300=6,367Nm.

[0031] The rated speed of generator 6 is 5,000rpm, the rated power of a single machine is 1,600kW, and the required torque of generator 6 is T=9,550X1,...

Embodiment 2

[0035] 3X30,000 kW single-machine large-scale power generation device, the 3 sets of generator sets have the same settings:

[0036] The diameter of wind turbine 2 is 3M, the thickness is 0.6M, the rated speed is 500rpm, and the weight is 500kg. According to the formula of moment of inertia: J=(m*r) / 2=(kg*r*r) / 2=500*1.5*1.5 / 2=562.5kg.m2, according to the torque formula: wind turbine main shaft 22 torque T=562.5 (3.14*3*500 / 60) / 0.9=49,062.5N.m.

[0037] The rated rotational speed of the auxiliary drive motor 5 is 300rpm, and the rated power is 1600kW. According to the calculation formula of torque, power and rotational speed: torque T=9,550X3,000 / 500=57,300Nm.

[0038] The rated speed of generator 6 is 10,000rpm, the rated power of a single machine is 30,000kW, and the required torque of generator 6 is T=9,550X30,000 / 10,000=28,650Nm.

[0039] The speed increaser 4 has an input speed of 500 rpm and an output speed of 10,000 rpm, and the gear ratio of the two is 20:1.

Abstract

Disclosed is an intelligent wind power generation device. The intelligent wind power generation device is composed of an iron tower, a wind turbine, a vertical transmission shaft, a speed increaser, an auxiliary driving motor, an electric generator, an underground electricity room and an electronic regulation and control center. According to the intelligent wind power generation device, natural wind power is utilized, and meanwhile the mechanical motor is used for auxiliary driving of the wind turbine, so that the wind turbine is kept rotating at a constant speed under the all-weather condition, and the requirement of all-weather full-load electricity generation is met. By the adoption of the low-speed high-torque motor, the wind turbine and the ultra high-speed electric generator device, the maximum power consumption of the auxiliary driving motor only accounts for 13% of electricity generation power of the electric generator.

Description

technical field [0001] The invention relates to the technical field of wind power generation. Background technique [0002] At present, wind power has certain instability and natural limitations. The average annual wind power grid connection capacity in my country is 16-18 million kW, and 10 million kW of the more than 90 million kW wind power projects that have been installed have not yet been connected to the grid. At present, if there is a large-scale increase in wind power installed capacity in a short period of time, it will greatly exceed the actual grid-connected capacity, which may make wind curtailment worse. Contents of the invention [0003] The invention makes use of natural wind power and at the same time uses a mechanical motor to assist the wind turbine to keep the wind turbine rotating at a constant speed all-weather to achieve full-load power generation all-weather and to remedy the defects of current wind power. [0004] In order to solve the above techn...
