Operation and connection modes
The power supply output is formed by three phases referenced to the neutral point of the
system (N). Consequently, the user can choose between two possible connection modes for the
grid emulator:
-
Independent phases: Three phase power grid. Each phase (U,V,W) is controlled
independently. The voltage setpoint can be different in angle and magnitude for each
of the three phases.
-
Parallel phases: One phase power grid. In this case the user has one phase output. The
total amount of current consumed will be the sum of all three phases.
And four operation modes are allowed:
-
Constant Voltage (CV): the output voltage is controlled to the setpoint value.
-
Faults generation (FG): the chosen kind of fault is applied to the output voltage.
Configuration and control of the power supply
The power supply can be interfaced by three means:
-
Local touchscreen: a 3.2” colour local touchscreen panel can be used to configure,
monitor and operate the grid emulator. See section
Local Touchscreen Control Panel
for
further information.
-
Analog inputs: the converter owns three isolated analog inputs (+/-10V) and two
optocoupled digital inputs (only available in case of AIO optional).
-
Remote interface: an Ethernet communication interface with protocol MODBUS/TCP
can be used to configure, monitor and operate the grid emulator. By using HMI software
application provided by CINERGIA, downloading of excel files is also possible.
