PowerApps Modules for Training Simualtors
The electric grid system operation is monitored and controlled at a centralized
control center commonly called load dispatch center or energy control center.
Continuous process industries and power plants may also have SCADA systems to
monitor the various process parameters and control the same including large
power plants along with their auxiliaries.
In general, where closed loop control is not
available or used, the real time measured and monitored variables will be
displayed on the operator's or dispatcher's console along with alaram for the
operator to take
action and to initiate the control process.
The operators may also have benefit of several calculations , analysis performed
on the real time measured data [for example the State Estimation in an EMS] and
tools to aid their decision taking process [for example optimal power flow]
Generally depending on the complexity of the process being monitored several
operator consoles may be used, each operator console displaying different portion of the process
being monitored or different aspect of the process being monitored and examined
by the operator.
Original SCADA/EMS vendors usually provide the training simulators along with
their SCADA/EMS solutions modeling the customer's plant process or the
electrical network or both. The system will idealy have a instructor control that
can assign a given operator's console as a trainee console without the knowledge
of the operator. The real time measurements received by the trainee console can
be changed from the measurements of the an actual process plant/network to
the measurements obtained from a "simulator" of the plant/network. The trainee will
not be aware that his console is receiving the measurements from the "simulator"
rather than from the real plant/network.
Without the knowledge of the trainee, instructor can now simulate the events in
the "simulator" and the results of the same will be displayed on the trainee
console. The operator/trainee will now respond to these events which are
intercepted by the instructor and implemented in the "simulator" model rather than
in real plant/network system. Such a training session will have all elements of
real time response situation.
At the end of the session, the instructor can discuss the training session with
the operator/trainee with the record of simulation stored and trainee/operator's
response.
PowerApps provide many interface facilities for such training simulation and
also the simulation modules needed for such Dispatcher/Operator Training
simulators. The solution provided by PowerApps can be customized to meet
specific client requirements.
