Unbalanced Network Load Flow

Unbalanced Network Load Flow Analysis

ETAP Unbalanced Network Load Flow Analysis module calculates the bus voltages, branch power factors, currents, and power flows throughout the electrical system.

ETAP allows for swing, voltage regulated, and unregulated power sources with multiple power grids and generator connections. It is capable of performing analysis on both radial and loop systems. The option to choose from several different analysis methods will achieve the best calculation efficiency.

The Unbalanced Network Load Flow module can operate in an offline mode utilizing user defined loading and generations. The application also interfaces with the online mode utilizing the status of the real-time system and estimated loading as well as voltages from the state and load estimation calculations in Real-Time mode.

A robust and efficient power flow solution method must be able to model special features of distribution systems with sufficient accuracy. With this application, you can easily model your unbalanced network system with detailed representation of component unsymmetrical characteristics. Accurate and reliable results are available describing your system’s unbalanced operating conditions.
