designed as an integrated engineering tool.
• It provides a complete 'walk-around' technique
through all available functions, rather than a
collection of different software modules.
• PowerFactory Version 14, DIgSILENT represents a
further step towards seamless integration of
functionality and data management within a
multi-user environment.

• This 'project and study case' approach to define and
manage power system studies is a unique application of
the object-oriented software principle.
• Standard software packages often require the user to
create a large number of similar saved cases, with
multiple nested directories for large complex networks
and studies.
• This approach of the structure is both easy to use while
avoiding redundancy.

• Stability analysis calculations are typically based on
predefined system models.
• When no IEEE models exist a powerful tools for
user defined modelling are required.
• For systems and configurations for which no IEEE
models exist, Dynamic Simulation Language
(DSL) could be used
• High specialised and exact models can be created in
PowerFactory.

• The Dynamic Simulation Language (DSL) is a powerfulfeature of DIgSILENT.
• DSL itself can be looked upon as an add-on to thetransient analysis functionality of PowerFactory.
• During the simulation, the model equations of the DSLmodels are combined with those describing thedynamic behaviour of the power systemcomponents.
• DSL and System equations are then evaluated together,leading to an integrated transient simulation of thecombination of the power system and its controllers.

1. Built-in models, which are standard electrical component
models, already existing in the DIgSILENT library.
2. DSL models, which are created by the user in the

• This modular structure has many similarities with the
first generation of WECC generic WTG model, but
also some major differences:
– The IEC structure separates the wind turbine
model from the wind plant model
– All the IEC models refer to a common modular
structure which applies for all wind turbine type
models.
– The common structure explicitly separates the
aerodynamic, mechanical, generator-system,
electrical and control modules and adds a grid
protection module.

connected to the rotor winding.
The power converter is ac‐dc‐ac system.
The power converter is usually the

• The fully rated WTG model could be used for:
– Load Flow Studies
– Stability Studies (RMS)
– Transient Studies (EMT)
– Balanced and unbalanced simulations (however control is
implemented for the positive sequence only)
• For dynamic simulation is a variable step size
possible.
• The minimum step size or the fix step size should
be lower than 5ms.

Grid side behaviour depends on:
• Control of the rectifier.
• Used step up transformer.
During fault:
• Low AC voltage on PCC no power feed in
possible.
• DC voltage is increased up to open-circuit DC
voltage.
• No special protection for solar cell needed.
