Abstract

This paper reviews the successful master controller revamp of Sappi Fine Paper North America's #3 paper machine at its Skowhegan, Maine mill. The rebuild project included upgrading the press section and increasing the speed of the paper machine by 500 FPM (150 MPM). The existing original drive system had been installed with sectional AC drives. The original drive system was becoming more difficult to maintain due to unavailability of parts and the out-of-date diagnostic system. The revamp involved the re-use of 76 existing drives and the installation of 8 new AC sectional drives. A new master controller was added with an enhanced diagnostic HMI. The new master controller architecture communicated with, controlled and diagnosed the old drives as well as the new drives. The unique combination of existing drives and new drives formed a cohesive system with all of the advantages of a new drive system. A staged installation was performed to reduce the outage time impact. The paper machine rebuild project was completed in March 2003 and has met the expectations of a successful revamp.

独特的纸机驱动系统改造

本文回顾了Sappi Fine paper North America在缅因州Skowhegan工厂的3号造纸机的成功主控制器改造。改造项目包括升级压榨部分，并将造纸机的速度提高500 FPM (150 MPM)。现有的原始驱动系统已安装了分段交流驱动器。原来的驱动系统变得越来越难以维护，由于不可用的零件和过时的诊断系统。改造包括重新使用76个现有驱动器和安装8个新的交流分段驱动器。添加了一个新的主控制器，具有增强的诊断HMI。新的主控制器结构既能与旧驱动器通信，又能控制和诊断新驱动器。现有驱动器和新驱动器的独特组合形成了一个具有新驱动系统所有优点的有凝聚力的系统。执行分阶段安装以减少停机时间的影响。造纸机改造项目已于2003年3月完成，并已达到成功改造的预期。
