Wind power plant data acquisition system

Abstract

The invention discloses a wind power plant data acquisition system. The wind power plant data acquisition system comprises a data acquisition assembly and a wind driven generator, the wind driven generator is rotationally provided with wind power generation fan blades in a matched mode, and meanwhile the wind driven generator is electrically connected with an electric power storage assembly. When the collected electric quantity in the electric power storage assembly corresponding to a certain wind driven generator in the wind power plant exceeds a set sufficient value, if the wind speed of the environment where the wind driven generator is located is lower than a certain value, the fixing assembly operates to fix the rotating end of the wind driven generator, namely, the whole wind driven generator is stopped, and when the wind speed exceeds a certain value, the rotating end of the wind driven generator is fixed. Even if the electric quantity in the electric power storage assembly reaches a certain value, the second wind speed sensor interferes with the effect of the first wind speed sensor, it is ensured that the fixing assembly cannot be triggered, normal operation of the wind driven generator is facilitated, and the situation that the benefit obtained by low-efficiency energy storage of the wind driven generator in unit time is lower than the loss maintenance cost of the wind driven generator is avoided.

Description

technical field [0001] The invention relates to the technical field of wind farm data acquisition, in particular to a wind farm data acquisition system. Background technique [0002] Wind farms are places for wind power energy conversion, mainly to install wind power generation equipment in places with natural wind energy to realize the function of converting wind energy into electric energy; general wind farms have data acquisition systems, which are used to Wind data and energy conversion data are collected and stored for research by relevant staff. Because the wind power generation equipment in the wind farm is easy to rotate and store energy under the action of low wind speed, and during the rotating operation, the entire equipment is lost and requires a certain cost of maintenance, and the wind turbine continues to perform inefficient energy storage. There is a situation that is lower than the loss and maintenance cost of wind turbines, but the data acquisition system ...

AI Technical Summary

Problems solved by technology

Because the wind power generation equipment in the wind farm is easy to rotate and store energy under the action of low wind speed, and during the rotation operation process, the entire equipment will suffer from loss, requiring maintenance at a certain cost, and the benefits of continuous low-efficiency energy storage of wind turbines There is a situation that is lower than the loss and maintenance cost of wind turbines, but the data acquisition system of general wind farms only has the ability to collect wind data and electric energy data, and cannot deal with this situation
