“Wide-area monitoring, protection, and control (WAMPAC) involves the
use of system-wide information and the communication of selected local
information to a remote location to counteract the propagation of large
disturbances.
Synchronized measurement technology (SMT) is an important element
and enabler of WAMPAC.
It is expected that WAMPAC systems will in the future reduce the number
of catastrophic blackouts and generally improve the reliability and
security of energy production, transmission, and distribution,
particularly in power networks with a high level of operational
uncertainties.”
V. Terzija et al., “Wide-Area Monitoring, Protection and Control of Future Electric Power
Networks”, IEEE Proceedings, vol. 99, No.1, pp. 80-93, January. 2011

• Motivation for WAMPAC
• Highly stressed, complex systems
• Reduced system inertia
• Increased instability
• Weakened reliability and security
• Blackouts (2003 US-Canada, 2003 Italy)
• Lack of real-time WAMPAC functionality
pointed to as root cause
• Synchrophasors/PMUs driving force1
• Reporting - SCADA: 0.25-0.5 Hz, PMUs: 30Hz+
• $357m invested by DOE and industry partners
under ARRA 2009
• 1700 PMUs provide near 100% visibility

49. – What did we covered?
– We learned about the Smart Transmission System Laboratory, which serves as a test9bench where new
WAMPAC software applications are developed and tested.
– Our laboratory, equipped with real9time simulators, PMUs and other equipment has allowed us to do
rigorous and scientific experimental testing of our research by performing RT9HIL simulations
– We showed how OSS Tools provides users the freedom real9time synchrophasor streams in the LabView
environment forrapid application prototyping.
– What is the future in WAMPAC?
– A more open market needs to be developed, and the foundational building blocks for the technology need
to be openly available (standards, their implementations, etc.)
– The feature, to me, seems quite limitedif the status quo continues.
– We hope to bridge this gap through our open source tools, to empower other researchers.
– What is the future for HIL?
– The full Model9Based approach should be better supported by technologies, i.e. avoid re9implementation
of applications / models / controls, etc., in n different systems.
– We need to support open standards for model9exchange (FMI Standard)
– We need to develop new and rigorous methods on how to test applications, HW and SW.
– What we learned by using HIL?
– It is really hard work to use the HIL approach, and it is even harder to get things published.
– We have learned more than what we expected (or wanted), and mastered the technologies.
– Nothing would have been possible without investing time in training my students, the highest value of a
lab is the individualsin it.
– Taking the next step was a 5 year process, and we believe that our work can help others – that’s why we
are sharing our tools as open source software.
