Power plant controllers in the WAPP system—including the governor, power system stabilizer (PSS), and automatic voltage regulator (AVR)—required tunings to keep the system synchronized. However, a dynamic study was needed to check system stability, and no dynamic plant models were available.
GE Vernova employed the Wide Area Monitoring System (WAMS) to monitor the entire WAPP system (in all ten countries) and the test synchronization. Phasor Measurement Units (PMUs) were installed, tested, and connected to provide data for monitoring. The synchronization test was successfully completed.
