Power System Handler
The DUtrain PowerSystemHandler is a unique tool for
simulating power system operations. Its technological design is based
on almost a decade of experience in operator training. The PSH briefly
described consists of
- a
SCADA system
- Models for the technical equipment
- Power system calculation engine
The SCADA system comprises the operational user interfaces
and the process data handling. The telemetric line interface is used
for the connection of, and the data exchange with, the models for the
technical equipment such as switching and protection devices, automatic
tap changers, generation units, load performance, etc. The power system
calculation engine simulates the physical performance of the entire
power system represented by the actual topology retrieved from the
SCADA system and the physical parameters of its equipment (e.g., line
and transformer impedances, generation capability, load trajectories).
The calculation results are sent back to the SCADA system as
measurement values.
Additional features of the OTS (DUtrain PSH) used here are:
- Representation of power system control hierarchical organisation comprising several control centres in parallel.
- Splitting of grid control and generation control, each represented in specifically customized control centres.
- Capability of technical equipment models and power
system calculation engine for 'normal' and 'abnormal' operational
conditions up to system restoration after full blackouts.
- Powerful scenario management.

Power System Handler
University BundleSince 2005 the PSH is available in a special university-bundle designed
for student labs. Today’s Electricity supply industry forces to operate
the entire power systems closer to their limits on the most cost
effective base. To cope with these requirements engineers are facing
new challenges in power system design and planning and in real time
operation including the operational planning as well.
During the past years DUtrain has developed the PowerSystemHandler
(PSH). The PSH is based on a full scale operator’s training simulator
displaying realistic performance of electricity supply systems in
operational time frame. The PSH has proven its capability in a lot of
training sessions covering system states from normal operating
conditions up to blackout scenarios. Furthermore PSH demonstrated also
its capability in the education of newcomers to the operational world.
DUtrain offers a special PSH bundle for Universities dealing with the
education of electrical engineers in the field of power systems’
engineering. Used in lab exercises the PSH gives insight into
- the operational performance of single pieces of equipment and the entire system,
- the technical phenomena occurring in power system operation under all system states,
- the interaction of power production, consumption and the electricity grid.
