SmarTS Lab — A laboratory for developing applications for WAMPAC Systems

Abstract

Abstract-At the core of the development of "Smart Transmission Grids" is the design, implementation, and testing of synchronized phasor measurement data applications that can supplement Wide-Area Monitoring, Protection, and Control Systems (WAMPAC). Nevertheless, the development of new PMU data-based WAMPAC applications has been relatively slow. The great potential of WAMPAC systems is being limited by this, and efforts are needed so that new applications can be developed. The slow rate of development of these applications is strongly related to, among other factors, the application development approach used. This article starts by discussing the needs and approaches for developing WAMPAC applications that exploit synchronized phasor measurements, and illustrates how one of these approaches has been achieved. A preliminary work carried out to develop and implement a Smart Transmission System Laboratory (SmarTS Lab), a hardware and softwarebased system for developing and analyzing "Smart Transmission Grids" paradigms and applications for WAMPAC systems, are described. The laboratory's conceptual architecture and hardware and software implementation are presented, and some of its components are described. Finally, the article illustrates proofof-concept examples of how PMU data-based applications can be developed.

Protection of AC and DC distribution systems Embedding distributed energy resources: A comparative review and analysis

“…In this protocol, the data is represented in an object-oriented manner and is transmitted multiple times to ensure its receipt. Moreover, IEC61850 can be used for time-critical applications where a fast protection scheme is required [94,95]. According to this protocol, a standard format is used for the data format which is communicated between Intelligent Electronic Devices (IEDs).…”

Voltage stability monitoring using sensitivities computed from synchronized phasor measurement data

“…Thus, to bridge the gap between theory and reality, a development and testing platform that performs as close as possible to real existing networks is adopted for the experiments involving real PMU data. This platform is available at SmarTS Lab, detailed information about this laboratory can be found in [21], a brief summary on how real-time data is generated is provided below. Figure 1 shows the overall architecture of the SmarTS Lab, where PMUs and protection relays are connected in HardwareIn-Loop (HIL) fashion with a Real-Time (RT) simulator to acquire three-phase current and voltage waveforms from a test system which is simulated in real-time.…”
