摘要
Abstract
An anti-interference domestic variable frequency multi-drive system solution for the five-stand continuous cold rolling line in the steel strip cold rolling field was presented.Firstly,the mechanical equipment and rolling process of the 900 mm five-stand continuous rolling line was introduced,and matched the models of domestic AC drive devices according to the motor table.The parallel connection mode of modular rectifier feedback power supply and inverter and the fiber optic communication were briefly described.Then,the problem of instantaneous drop of the incoming grid voltage encountered by the common DC bus system and how to improve the system stability by adding capacitor banks were discussed.At the same time,the method of using encoder isolation distribution board was introduced and providing separate power supply for the encoder to solve the encoder signal interference problem.Finally,the anti-interference performance of the system was verified by comparing the speed and torque accuracy before and after the improvement.关键词
