Emerson Extends Control System Capabilities with Integrated Generator Excitation
Melissa Larson | December 10, 2014
Emerson Process Management has integrated generator excitation capabilities into its Ovation control system for more reliable power plant operation. This capability helps to better control the generator and, in doing so, contributes to grid stability.
Built on the Ovation control system platform, the Ovation generator excitation system offers precise excitation control for rotating, brushless or static exciters. The flexible, single-platform design allows it to be applied to generators with field current requirements of up to 8,000 amps.
While Emerson has provided excitation systems for some time, this new solution leverages the power of the Ovation platform through a high-performance I/O module dedicated to excitation control functions. Having native generator excitation capability on the Ovation platform provides a number of advantages to power generators:
Designed for any synchronous generator including those in hydro, fossil and nuclear power plants, the Ovation generator excitation system features integrated Power System Stabilizer software and a full suite of limiting and protection functions. The system is applicable to both new construction and retrofit projects, and Emerson’s team of excitation experts can tailor it to accommodate any plant’s unique layout and generator design.
