Embodiment Construction

[0027] to combine figure 2 , a wind turbine simulator suitable for testing direct-drive wind turbines, including two parts: a prime mover system and an upper computer. The prime mover system includes a frequency converter, a three-phase asynchronous motor and a reduction gearbox. The asynchronous motor is electrically connected, and the three-phase asynchronous motor is mechanically connected to the reduction gearbox. The frequency converter receives the torque command sent by the upper computer, and adjusts the output torque and speed of the low-speed shaft of the reduction gearbox according to the torque instruction; the upper computer includes data acquisition. Card, industrial control computer, rotational speed encoder, anemometer, the rotational speed encoder measures the rotational speed of the three-phase asynchronous motor, and transmits the rotational speed signal to the data acquisition card, and the anemometer transmits the measured wind speed signal to the data acq...

Abstract

The invention discloses a wind turbine simulator which comprises a prime motor system and an upper computer, wherein the prime motor system comprises a frequency converter, a three-phase asynchronous motor and a reduction gearbox; and the upper computer comprises a data acquisition card, an industrial control computer, a rotating speed encoder, an anemometer and wind turbine simulation software. In each working cycle period of the wind turbine simulator, the upper computer acquires the rotating speed and wind speed signal, calculates the output reference torque of the prime motor system through the wind turbine simulation software and transmits the output reference torque to the frequency converter in the prime motor system; and the frequency converter controls and adjusts the output mechanical torque of the reduction gearbox through the torque. Aiming at the output characteristics that the conventional wind turbine simulator based on the three-phase asynchronous motor hardly realizes low rotating speed and high torque, the invention provides the wind turbine simulator applicable to testing of a direct driving type wind generating set.

Description

technical field [0001] The invention belongs to the technical field of wind power generation and testing thereof, in particular to a wind turbine simulator suitable for testing direct-drive wind turbines and a type selection method thereof. Background technique [0002] As a renewable clean energy, wind energy has been paid more and more attention by countries all over the world. The development and utilization of wind energy and the vigorous development of wind power generation technology are of great significance for solving the global energy crisis and environmental pollution. Although the most convincing test method is still the field experiment of wind turbines in the wind farm environment. However, the wind power simulation experiment platform with low cost, safety and reliability, easy installation and maintenance, and easy control of experimental conditions is very suitable for wind power scientific research institutions with preliminary research or limited funds. ...
