The coiler of steel rolling production system

in case of power supply by power network

is normally divided into such two types as multiple coiling motors with one rectifier transformer for power supply and single motor with single rectifier transformer for power supply. Since existence of electric and power generation in the coiler and different power supply of network

the corresponding filtering compensation capacity is different in the design of dynamic filtering compensation device of coiler. According to the engineering application

the coiler concentrated and local dynamic filtering compensation design and operation effect is summarized. The difference of filtering compensation design scheme at the two power supply modes is introduced

which provides reference for filtering compensation design of DC drive system and rated capacity selection of rectifier transformer.
