Symphony Plus for one of the largest PV solar project in the US

ABB is supplying a Symphony Plus solution for a new 125 MW photovoltaic power plant in Arizona.

ABB has won a contract from Fluor Corporation to supply a Symphony™ Plus plant automation system for the Arlington Valley Solar Project (AVSE II) at Arlington. The plant is scheduled to become operational in 2013. It will consist of five array blocks of PV panels made of crystalline silicon cells on a single axis tracking system.

The Symphony Plus system will monitor and control the various plant systems, including trackers, inverters, substations, the well water supply and treatment system, and the interface with the plant meteorological station.

Relevant plant information will be made available to a remote site and to the California Independent System Operator. All plant data will be synchronized using two GPS clocks in primary and backup configuration.

ABB's scope of supply includes S+ Operations as the system’s Human Machine Interface (HMI) to fulfill stringent requirements of scalable yet flexible architecture. S+ Operations will support 60,000 redundant tags with 1,000 historian logs. Hardware provided by ABB includes one remote terminal unit, 67 network switches, a GPS clock, control room furniture, two server/client PCs, one client PC, eight communication servers, two printers, UPS backup power supply, and one engineering station.

This advanced solution from ABB adds value to the operations and maintenance of this project by maximizing plant availability, production efficiency and overall low maintenance costs. Green energy delivered from this project will be beneficial for the state of California, which has its own green energy efforts.
