DSATools PSAT 14.0

DSATools PSAT by Powertech Labs Inc. is a steady-state power system analysis module designed to evaluate and secure transmission networks. It provides fast, numerically robust AC and DC power flow, short-circuit/fault calculations, and automated N-1/N-k contingency screening. Engineers use PSAT to detect overloads and voltage violations, rank critical contingencies, and test corrective actions such as re-dispatch, topology changes, and reactive support adjustments. Built to handle very large models, it offers detailed equipment representations and clear, actionable reporting for planning, operations planning, and study-mode support.

As part of the DSATools suite, PSAT integrates seamlessly with companion modules—such as VSAT for voltage security and TSAT for transient stability—to enable a unified workflow from model preparation to comprehensive security assessment. Typical applications include outage and seasonal studies, transfer capability analysis, operational limit determination, and rapid what‑if evaluations that help utilities maintain reliability and meet regulatory and reliability standards.
