Abstract

The invention discloses an automatic detection system and method for functions of a wind power variable-pitch capacitor charger. The system and the method are based on a PLC with DI detection, voltagedetection, current detection and DO control functions and an automatic voltage regulator. The input voltage of a variable-pitch capacitor charger is controlled by an upper computer, the functions ofthe capacitor charger are automatically detected, functional data of the capacitor charger is recorded, possible abnormal problems of the variable-pitch capacitor charger are objectively judged through a solidified test program, the labor cost and the time cost are saved while full-function detection of the capacitor charger is guaranteed, and the power utilization risk in the capacitor charger test process is reduced.

Description

technical field [0001] The invention belongs to the technical field of capacitor chargers for wind power pitch systems, and relates to an automatic detection system and method for the function of a wind power pitch capacitor charger. Background technique [0002] As an important component of the wind power main brake system, the wind power pitch motor is directly related to the safety of the wind power machine. In recent years, with the continuous development of pitch technology, supercapacitors have replaced lithium batteries as the backup power supply for pitch systems. In order to ensure sufficient and stable energy stored in capacitors and improve their own operational reliability, capacitor charger technology has also been continuously improved. [0003] After the pitch capacitor charger is connected to the 380V AC power supply, it will charge the capacitor with a set constant current to maintain a constant capacitor voltage and continuously output working signals; due ...
