Abstract

The invention belongs to the technical field of wind power generation, and particularly relates to a fan variable pitch driver automatic testing system. The automatic testing system is applied to in-plant testing for an alternating current servo driver of an electric variable pitch system of a large wind turbine unit, and is mainly composed of a PLC (1), a test driver (2), a tested driver (3), a supercapacitor group (4), a motor I (5) a motor II (6), a capacitor charging and discharging resistor (7), a Hall sensor (9), a bus connection relay switch (10), a capacitor charging relay switch (11), a capacitor discharging relay switch (12) and a capacitor power supply relay switch (13). The automatic testing system is mainly applied to automatic detection for hardware functions and overall performance of a fan variable pitch driver. The automatic testing system not only can complete testing work for the variable pitch driver quickly and effectively, but also reduces requirements for the operating personnel and optimizes the human resource cost.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to an automatic test system for a wind turbine pitch driver. Background technique [0002] With the acceleration of world energy consumption and the reduction of traditional energy reserves, wind power, a green energy with inexhaustible advantages, has attracted more and more attention from human beings. As an important form of wind energy utilization, wind power has been supported by various policies around the world. In recent years, domestic and foreign wind power generators have gradually developed towards large-scale, and my country's wind power industry has also developed rapidly. [0003] The wind turbine pitch system is used to adjust the angle of the blades of the wind turbine, and is one of the safety control devices of the wind turbine. When working, the pitch control system receives control commands from the main control system of the fan, con...
