Generator Commissioning

Ensuring that power system oscillations are always adequately damped is a major challenge in the operation of power systems.  For one national transmission operator, the unique topology of its grid meant that stability of oscillations was a major concern.  In particular, the connection of a very large hydro plant to a weak part of the network required careful observation and management of the stability of the network.

The Psymetrix solution was to install a WAMS (Wide-Area Monitoring System), aiming to observe damping of system modes across the network for a pre-specified time period, as a means of identifying damping issues that may not have been represented accurately in the dynamic model of the system.

Installation of Psymetrix's WAMS-based tools and approaches for identification and characterisation of the operator's system dynamics significantly improved the operator's capability to manage its power system dynamics.  Emerging stability problems were detected before they became critical, allowing the operator to make informed choices on how to manage the risks to system stability.  Importantly, evaluating the effectiveness of damping controllers on critical modes has now become an important function of the operator's monitoring system.
