Statement of Work Testbed Implementation for Wide Area Monitoring and Measurement of the Power Grid;

Scalable Synchrophasors Communication Network Design

I. BACKGROUND

The Advanced Network Technology Division (ANTD) at the National Institute of Standards and Technology (NIST) is currently working to develop a wireless network for wide area measurement systems. Much work has been done to implement a real-time network testbed consisting of many Phasor Measurement Units (PMUs) located at various key substations. For a distributed generation this would require the deployment of PMU’s at critical locations, which implies accurate phase measurement with the support of a low delay, highly reliable network infrastructure. In the absence of such a network, the most cost-effective solution would be to consider a wireless network to support centralized control for situational awareness in the transmission as well as the distributed generation grid environment.

The objective of this project is to design a scalable Wireless LAN (WLAN) based network, such as IEEE 802.11, to assess network performance and requirements under real world conditions. The plan is to design and implement a network testbed that includes an emulation platform to support the Physical (PHY) and Medium Access Control (MAC) layers.

II. SCOPE OF WORK:

The Contractor shall implement an Emulab-based testbed consisting of a hierarchical network where the phasor information is transported to the final destination through different levels of PDC’s (Phasor Data Concentrators). The contractor shall also develop a high speed software package for data communication at the application layer based on the IEEE C37.118-part-II standard.

IX. MINIMUM CONTRACTOR QUALIFICATIONS

The tasks and deliverables defined in this PWS require the Contractor to possess theoretical knowledge and practical experience in wireless communications, wireless ad hoc networks, and in particular, synchrophasor networks with load balancing capability when the network has multiple gateways (e.g. mesh portal nodes). In addition, the contractor would have to be proficient in the use of ns2 network modeling and developing codes for the Emulab-based simulation tool in order to build upon the test tool developed during the course of this project.
