PowerSystems

The library is intended to model electrical power systems at different levels of detail both in transient and steady-state mode.

Library description

PowerSystems provides a framework and examples for the flexible modeling of electical power systems. Generic component models adapt to different application needs by using a replaceable PhaseSystem. Moreover the library contains the extensive sets of detailed one phase and transient three phase component models of the former SPOT library.

In particular this shall cover systems like:

• AC power systems, including dc power flow, steady-state, transient, and unsymmetric,
• Variable frequency systems, e.g. in wind turbines or for drive control, and
• DC power systems, like HVDC
