PowerFactory Areas of Application

Power Transmission

A fast-changing sector where grids are seeing a switch from traditional base-load generation to new sources such as wind and solar. PowerFactory is ideal for studying interconnected power systems and for transmission operation planning.

Power Distribution

PowerFactory provides comprehensive modelling for studying all kinds of electrical networks with different phasing technologies. It has a wide range of functions to improve quality of supply and optimise distribution networks.

Industrial Systems

High precision load flow algorithms, flexible short-circuit calculation features, protection system modelling and harmonic analysis are among the functions offered by PowerFactory. This ensures continuity of production and safety for industrial networks.

Power Generation

Analysis tools include models of generators, motors and protection relays, calculation of short-circuit currents, stability and EMT simulation and modal frequency response to ensure power plant reliability and efficiency.

Distributed Generation

PowerFactory enables the analysis of challenges including reverse power flows, voltage dips and swells. It can also address the issue of forecasting renewable energy generation and the impact of smart grid technologies.

Renewables

Integrating renewable generation into electrical networks is a key industry activity.  PowerFactory provides the tools to undertake a full range of studies required for grid connection, grid impact analysis and fault ride through (G.99) studies for windfarms, solar plants and other renewable energies.
