Abstract

The invention provides a wind generating set power characteristic testing system based on a DSP, and mainly relates to the field of wind generating set power characteristic testing and analysis. The wind generating set power characteristic testing system based on the DSP comprises a host processor, a DSP chip, a wind speed sensor, a wind direction sensor, a temperature sensor, an air pressure sensor, a current sensor and a voltage sensor. The wind generating set power characteristic testing system is characterized in that Python software is arranged in the host processor, the DSP chip is in serial communication interface (SCI) connection with the host processor, and the wind speed sensor, the wind direction sensor, the temperature sensor, the air pressure sensor, the current sensor and thevoltage sensor are electrically connected with the DSP chip. The wind generating set power characteristic testing system based on the DSP has the beneficial effects that the accuracy of testing the power characteristic of a wind generating set is improved, so that equipment is more portable; and a good man-machine interaction interface is achieved so that data can be displayed and analyzed in real time.

Description

technical field [0001] The invention mainly relates to the field of testing and analyzing the power characteristics of a wind power generating set, in particular to a DSP-based power characteristic testing system for a wind generating set. Background technique [0002] my country's research on the power characteristics test of wind turbines started late, and it is relatively backward compared with foreign countries. However, after years of hard work, a unified standard has gradually been formed for the power characteristics test of wind turbines. It is formulated according to IEC61400-12-1 National standard GB / 18451.2-2012 Test method for power characteristics of wind turbines. The standard system for testing the power characteristics of wind turbines has been preliminarily formed, which has improved the capabilities of testing, evaluating, and certifying the power characteristics of wind turbines. Perfect, the experimental and testing facilities are not yet complete, there ...
