WAMS Design and Deployment

Conventional SCADA systems are limited to steady-state measurements and cannot be used for observing system dynamics. Synchronised phasor measurement devices such as Phasor Measurement Units (PMUs), however, are now a proven technology. providing accurate time-stamped measurement data suitable for observing power system dynamics.

The deployment of PMU devices to provide data acquisition in Wide-Area Monitoring Systems (WAMS) brings a whole range of new issues far removed from traditional SCADA/EMS. Data transmission rates and data volumes are substantially higher.  However, unfamiliarity with the range of WAMS building blocks, visualisation options and advanced applications can result in poor system choices and the deployment of under performing and unreliable systems.

The Psymetrix PhasorPoint solutions architecture provides a full-range of scalable building blocks for synchrophasor measurement and monitoring systems. The wide-range of easy to use functionality available includes efficient real-time data management, archiving, visualisation and advanced applications. These applications include an enhanced version of the industry-leading Psymetrix oscillatory stability monitoring technology.

PhasorPoint solutions work with all PMU devices that support the IEEE C37.118-2005 standard and Psymetrix has extensive experience of working with PMU's from a number of different vendors and partners.

In addition to providing PhasorPoint, Psymetrix can assist with the design of WAMS that are flexible, scalable and reliable. Systems covered range from small-pilot schemes right up to large-scale deployments. The Psymetrix approach ensures the WAMS design is suitable for the available or planned communications infrastructure, and that appropriate phasor data concentrator architecture, applications and integration required are delivered. Finally, Psymetrix can also implement and manage entire programmes for WAMS deployment.
