Description
Application Scenarios
In a recent upgrade at a regional power plant in Southeast Asia, engineers faced challenges with voltage instability during peak load conditions. The existing analog AVR struggled to maintain consistent voltage levels, leading to frequent fluctuations and potential equipment damage. By installing the WOODWARD DECS-100-B15, the plant achieved precise voltage control, significantly improving power quality and reducing the risk of voltage-related disruptions.
Another compelling use case involves a remote telecommunications facility in Northern Canada, where reliable backup power is critical. The site relies on a diesel generator equipped with the WOODWARD DECS-100-B15 to provide stable voltage during grid outages. The AVR’s ability to quickly respond to load changes ensures that sensitive communication equipment remains operational, even during sudden power demands or fluctuations.
