SIGUARD®DSA – transmission system stability and dynamic security assessment

SIGUARD®DSA – your solution for a fully automated and integrated dynamic stability assessment for any size transmission system

Fully automated and integrated dynamic stability assessment for any size transmission system

The growing complexity of the grid has forced power systems to operate closer to stability limits than ever before – increasing the risk of blackouts. Transmission network operators can no longer only rely on data acquisition and static n-1 analyses to make critical remedial decisions. SIGUARD®DSA helps system operators expand their situational awareness in the control room, and supports them in making critical decisions during stability problems.

SIGUARD®DSA software

Analyze an entire range of stability issues for real-time and future scenarios

SIGUARD®DSA is a model-based dynamic stability assessment tool for online control room use and offline operational planning purposes. Contingency study cycles are run automatically, taking the most current snapshot from the SCADA system as a basis. By utilizing the high-speed simulation engines from the PSS® portfolio, it allows users to perform a wide variety of stability analysis functions, including voltage, transient, small signal, oscillatory, and much more.

SIGUARD®DSA offers a wide range of stability solution capabilities and clear advantages for any transmission system.

Powerful multi-level visualizations for operators and planners

From high-level visualizations to detailed root-cause analysis

The SIGUARD®DSA cockpit displays the highest level of aggregated data with a simple interactive traffic light visualization. This representation shows the effects of system disturbances as well as the origin of the stability problems, allowing the operator to define possible contingency solutions. Through the multi-level visualizations users can identify:

  • the contingencies causing the disturbance – sorted by issue severity,
  • the physical phenomena creating the stability issue, such as voltage, transient and small signal
  • the core element(s) involved including details on the level of single generators, bus voltage currents, etc.

Drill down into more detail by exporting the simulation case, and using a simulation engine such as PSS®E or PSS®SINCAL.
