数字控制交-交变频调速技术在热连轧机中的应用

The Adjusting Speed Application of Digital Inverter in the Continuous Rolling Mill

轧机的电机功率大,干扰严重,其调速精度难以控制,文章提出的数字控制调速技术先进、可靠,解决了上述问题。变频对电网的谐波采取了滤波措施。对于变频调速的设计应用具有很大参考价值。

The paper brings forwards the adjusting speed technology to solve the problem of power big and disturb of motor and precision control difficulty. We adopt measure of filtering wave for the electric net by:inverter. It has important values for the design and application of adjusting speed of inverter.
