Abstract

The invention relates to a breeze generator power control method, device and system, and the method comprises the steps: obtaining the current wind speed and the internal coil current of a breeze generator; querying a pre-established PWM duty ratio data table according to the current wind speed and the internal coil current to obtain an optimized PWM duty ratio; and according to the optimized PWM duty ratio, the breeze generator is controlled to work, so that the breeze generator can stably output the maximum electric power, and the power control efficiency of the breeze generator is improved. When the current of the internal coil of the breeze generator changes, namely the electromagnetic resistance changes, the PWM duty ratio is adjusted in time, and the latest maximum power point is found again; the current wind speed is monitored in real time, and the PWM power control mechanism is optimized according to the characteristics of natural wind when the wind speed changes in real time, especially in a second level, so that the power control of the breeze generator is more efficient and intelligent.

Description

technical field [0001] The present application relates to the technical field of power control, and in particular, to a power control method, device and system of a breeze generator. Background technique [0002] A wind turbine is a device that uses wind to drive mechanical rotation to generate electricity. With the increasing development of science and technology, the technology of modern wind turbines using wind energy to generate electricity is becoming more and more mature, and the efficiency is getting higher and higher. At present, with the increasingly tight energy demand and the increasing pressure of environmental pollution, wind energy, a clean, environmentally friendly, non-polluting and low-cost power source, has received more and more attention. Although the installed scale of large-scale onshore wind turbines and large-scale offshore wind turbines is increasing and developing rapidly, it is necessary to generate electricity when the wind speed is above 4-5m / s....
