Symphony Plus upgrade for one of the US' most efficient power generation units

S+ Operations provides a low-risk evolution, high-quality, state-of-the-art solution
ABB has successfully commissioned a Symphony™ Plus upgrade at Tampa Electric’s (TECO) Polk Power Station in Florida.

Polk Power Station is an integrated coal gasification combined cycle (IGCC) power plant with a generating capacity of 260 MW. The plant began commercial operation in 1996 and is among the nation's cleanest, most efficient and most economical power generation units.

ABB replaced the existing INFI 90 virtual memory system (VMS) consoles with the powerful and ergonomic S+ Operations Human Machine Interface (HMI), which is designed specifically for power generation and water applications.

ABB was selected for the project thanks to its low-risk solution that brought the plant into a modern operating environment in the most cost-effective manner, and for the inherent advantages of its simple, scalable, seamless and secure Symphony Plus control system.

"ABB’s evolution of operating displays provided an economical solution to upgrading from VMS consoles. It provi-
ded our operations team with a familiar operating environment, while at the same time adding important new functionality,” said Tom Cross, DCS Specialist, Tampa Electric. “The new Symphony Plus HMIs were commis-
sioned while the existing VMS consoles continued to operate. This allowed us to greatly reduce project risk, while allowing our operators the time they needed to become comfortable and proficient with the new system.”
