An electric power system encounters with different
operational dynamics on its generation units that is affected by
different items such as limitations of turbine-governor response,
the importance of accuracy, dynamic modeling and model
validation, and system design and operational scenarios. To
prevent system frequency collapse and consequent events, it is
necessary to assess the operation of turbine-governor units. This
paper discusses the conceptual design and operation of an isolated
real-time power system simulator. This simulator that is named
hereafter as real-time isolated simulator (RTISim) along with all
of its related equipment, can evaluate power plant performance in
order to verify the speed droop, and power turbines capabilities.
RTISim replaces the real system frequency and active power
feedback of the governor by a simulated frequency and active
power which are produced in LabVIEW software environment. In
this case, the turbine-governor capability can be investigated in
isolated network without being disconnected from the grid and
thus, the risk of operation of islanded/autonomous system during
the test, can be eliminated. LabVIEW, as a real-time simulation
software, is used to simulate different events and record related
results such as frequency deviation and active power changes.
These data can help engineers to model turbine-governor of
industrial power plants in power system analysis tools as precisely
as possible.
