Simscape Power Systems Power Transmission

Power Transmission

Simscape Power Systems enables you to model complete electrical networks and grids so you can use simulation to explore and improve grid stability.

FACTS

Models of power electronics-based FACTS systems help you use simulation to improve power transmission capabilities of your networks. You can add devices such as static VAR compensator (SVC) and unified power flow controller (UPFC) to your grid models to control power flow, improve transient stability, and relieve power congestion in a transmission system.

Sandia National Laboratories Integrates Photovoltaics with Microgrid (User Story)
Engineers at Sandia reduced model development time by 80%, lowered the cost of the final system by $200,000, and validated their model against field data.

Transmission Lines

Simscape Power Systems provides models for single and multiphase transmission lines and cables. You can use a PI section model to study the interactions between power systems and control systems, or use a distributed parameters model for tests that involve high-frequency transients. A graphical tool is provided to calculate key parameters based on line geometry and conductor characteristics.

Transformers

Simscape Power Systems includes models for single and multiphase transformers, such as delta-delta, wye-delta1, and zigzag-delta1-wye. Parameterization options let you specify nonlinear behavior such as saturation, varying core dimensions, and hysteresis. Examples show you how to create custom models either graphically or via equations in the Simscape™ language.
