Emerson has launched automation technology for utilities and independent power producers that rely more and more on diverse renewable energy sources and that serve the fast-growing microgrid market. Its new, modular Ovation OCC100 controller cost effectively extends Emerson’s proven Ovation control technology by managing the flow of energy from various sources to ensure continuous, reliable generation for these emerging industries. This small footprint, scalable technology is also well-suited to critical water and wastewater applications.
With renewable electricity capacity expected to expand by over 920 gigawatts – an increase of 43 percent – through 2022, according to a 2017 International Energy Agency report, the OCC100 controller is suitable for power generators with growing and diverse renewable generation portfolios (including hydro, solar and wind) and microgrids that rely on a variety of distributed energy resources.
The OCC100 offers remote monitoring and control capabilities for wind farms spread out over a wide geographic area and the ability to operate in the higher ambient temperatures associated with solar facilities. For microgrids, it provides a single point of control for performance optimisation. Similarly, the new controller efficiently monitors and controls remote pump stations critical to collecting, treating, storing and distributing water to homes and businesses.
Today, power generation and water/wastewater facilities often rely on non-integrated programmable logic controllers (PLCs) with limited functionality to automate smaller, stand-alone equipment or processes. These “islands of automation” limit broad information-sharing necessary for optimal operational efficiency.
In addition to operating independently, the new controller can be natively merged into a larger, Ovation distributed control system offering greater visibility into plant-wide operations. The controller also features integrated wide-area technologies that allow it to control geographically dispersed equipment using cell or other wireless technology. This capability will help power generators harness the benefits of Industrial Internet of Things (IIoT) like never before. For example, as wind power becomes more prevalent and wind turbines become larger and more sophisticated, utilities need to more closely monitor vibration and other operating conditions. The OCC100 controller collects and aggregates information about each wind turbine, then shares that data to provide intelligence about the entire wind farm. This intelligence can be assimilated with information about other facilities in the power-generating fleet.
“Traditionally, the power generation industry has been slow to change. But now with microgrids moving into the mainstream and an increased reliance on renewable energy, it’s really a brave new world,” said Bob Yeager, president, Power & Water, Emerson Automation Solutions. “We’re adapting to the changes we’re seeing in the global power markets, offering our customers the enhanced flexibility they need to thrive in this changing landscape.”
