Abstract

The invention discloses a draught fan converter management system; the draught fan converter management system comprises a data collecting device, a wireless communication device, a control device and a management device; the data collecting device is used for collecting running parameters of a converter which is mounted on a wind power generator; the wireless communication device is used for implementing wireless communication; the control device is used for controlling the data collecting device and the wireless communication device; and the management device communicates with the wireless communication device. Comparing to the prior art, the disclosed draught fan converter management system achieves remote monitor and management of the running parameters of the converter of the wind power generator, thus saving manpower, and reducing the maintenance cost.

Description

technical field [0001] The invention relates to a management system, in particular to a wind turbine converter management system. Background technique [0002] Wind turbines convert the kinetic energy of wind into electrical energy. As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. As the wind speed changes, the rotational speed of the generator also changes, so the voltage amplitude and frequency output by the generator change, while the voltage amplitude and frequency of the grid are constant. In order to send the alternating current with varying frequency and amplitude output by the generator to the grid, the converter acts as an intermediate link. The normal operation of the converter is related to whether the wind turbine can feed stable electric energy into the grid. Therefore, it is necessary to monitor the converter to obtain the operating status of the converter in real time. Because wind turbines ...
