SIPCO's Marion Station Realizes Outstanding Success with Emerson's Ovation System
With circa 1960s and 70s analog and pneumatic Bailey controls on the Marion plant, the existing equipment was well past its useful life. SIPCO wanted to integrate the latest technology into the plant, while developing a strong alliance with their DCS vendor for ongoing support and development of their long-range vision. The project came with a series of unique constraints. Limited resources required that the system be easily implemented without excessive demands on the plant staff. In addition, the system had to meet operating requirements while falling within budget constraints. One of these constraints was that the existing boilers needed to continue to operate while the system was being installed. The first Ovation Solaris-based system was installed in Spring 2000 on Unit 4 for boiler control, cyclone management control, miscellaneous control, motor control, and data acquisition.
Phase two of the project included repowering of units 1, 2, and 3. Emerson installed another Ovation Solaris-based system on new CFB boilers and repowered existing Allis Chalmers turbines. Emerson then replaced existing controls on the Unit 4 wet scrubber and incorporated the balance of plant for new GE Frame 7 turbines into the Ovation system. This was the largest undertaking of the entire project, and it included installation of the new Ovation system, new boilers, and new turbines.
Results
- Dramatic improvement in information management
- Improved data acquisition capabilities throughout the plant
- 20% improvement in reliability and availability
- 10% improvement in equipment wear
- Significant reduction in temperature swings and spikes
