EXPERIENCE SCOPE

Strategy & Innovation

The Grid

State Estimator - TNA

study contingencyanalysis and a study state estimator to test these model datachanges, as well as functionality to manage informationassociated with model data.

Software

a compilation of a few systems used between TP, SE and SP.

SGem

SGEM is a powerful data modeling, data maintenance anddata exchange tool specifically designed to cost effectivelyand efficiently manage any power system model data

Cape

CAPE (Computer-Aided Protection Engineering) software is built for engineers responsible for protection of high voltage transmission systems and distribution systems within electric power utilities

Application Diagram

a very general overview

interactive power system simulation package designed to simulate high voltage power system operation; power flow analysis solver.

PowerWorld

 PSS®E allows you to perform a wide variety of analysis functions, including power flow, dynamics, short circuit, contingency analysis, optimal power flow, voltage stability, transient stability simulation.

PSSE

collect, analyze, visualize and share large amounts of high-fidelity, time-series data from multiple sources to people and systems across all operations.
