Hydroelectric Powerhouse Sequential Event Recorder and Annunciation Upgrades – Design Philosophy and Lessons Learned

摘要

The US Army Corps of Engineers owns and operates 75 hydroelectric powerhouses throughout the United States. Many of our hydroelectric powerhouses still use light box style annunciators with hardwired inputs. These annunciators have been very reliable but provide limited information and are difficult to modify in the future for changes in the powerhouse. As part of our powerhouse modernization efforts we have been looking at ways to improve the powerhouse annunciation systems. Some of the goals of this modernization are to improve the situational awareness of our control room operators, provide a means to record and timestamp the alarms as they come in, and provide a system that is easily modified. We are also interested in a scalable design that can easily be implemented at different powerhouses.
