SIGUARD®DSA – transmission system stability and dynamic security assessment
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.
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.
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.
Increase situational awareness and ensure stability
Implementing this new SIGUARD® DSA solution in our control room environment has streamlined our processes for stability awareness and enhanced our capabilities for power system analytics with PSS®E. We are looking forward to continue the collaboration with Siemens in the next phase.
Control center of the future
Research and scientific partners in Germany cooperated in the DynaGridCenter research project to develop advanced assistant systems for automated grid control and outage prevention.
As the core of the project, a dynamic grid control center, based on Siemens Spectrum Power, was installed at the Technical University of Ilmenau. Newly developed dynamic applications are integrated as assistant systems for functions like “Dynamic Security Assessment,” “Adaptive Protection Settings” and “PMU Data Streaming Analytics.”
