Voltage Stability Analysis

Improve Network Security & Identify System Loadability
Voltage collapse is still the biggest single threat to the transmission system. It is generally characterized by loss of a stable operating point as well as by the deterioration of voltage levels in and around the electrical center of the region undergoing voltage collapse.

Voltage collapse is still the biggest single threat to an electrical network. Voltage stability is an important factor, which is taken into consideration during the planning and operation of electrical power systems to avoid voltage collapse and subsequent partial or full system blackout. Voltage instability is generally characterized by loss of a stable operating point as well as by the deterioration of voltage levels in and around the electrical center of the region undergoing voltage collapse.

ETAP Voltage Stability module utilizes existing electrical model used for power flow studies to assess static voltage stability using typical methods: V-Q curves, P-V curves and V-Q sensitivity analysis.
