DSATools™ Other DSA Tools Module | VOB Visualize Power System Security Limits

VOB

Visualization of System Security Boundary

reduce the complexity of large-scale dynamic models while preserving key system behaviors, making stability studies more efficient and manageable.

Interactive Limit Mapping

Displays 1D and 2D PV/QV curves, interface limits, and thresholds.

Scenario Comparison Views

Overlay base case and contingency boundaries for at-a-glance insight.

Supports Operator Decision Making

Visual tools support dispatch, planning, and risk assessment.

Integrates with DSA Manager

Displays violations or limits directly from online security assessments.

Visualization of Systems Security Boundary

VOB is a software program sponsored by EPRI (US) and developed by Powertech. It is for the real-time visualization of on-line DSA results, as well as display of PMU measurements. Currently, it accepts security assessment results in DSATools™ format and PMU data in IEEE C37.118 format.
