PAS/PFV Series
PAS Series product
is developed for renewable energy related applications. It can simulate the
various grid conditions and related test standards. Especially the voltage or
frequency transient simulation test feature, it is suitable for production,
quality verification, research and development.It also builds in with Low
Voltage Ride Through Test (LVRT) test function, step mode and gradual mode
programmable capability.
PFV Series is a new generation of programmable AC power supply, with four
quadrant energy feedback function. This unit not only provides power to the
EUT, but also sinks the power back to the grid system which is useful for grid
tie devices testing applications. The maximum output power for PAS series is up
to 2000kVA, and the PFV series is up to 200kVA. The output voltage range is
0~300VL-N and the standard output frequency is 45~65Hz continuously adjustable
(optional 40~70Hz).
Regenerative
Function
PAS series is a
four-quadrant AC power source which is capable to be a power source or sink the
power from the EUT back to the grid system with 90% efficiency. It is suitable
for PV Inverter test, EV charger test or other grid tie devices test. Build in
with Low Voltage Ride Through (LVRT) test graph and it is very suitable for
IEEE-1547 or BDEW related standards compliance test.
Low Voltage Ride
Through (LVRT)
Built-in Low
Voltage Ride Through (LVRT) mode can simulate the grid in abnormal conditions.
The settings include rated voltage, frequency, drop voltage, recovery voltage,
rise time and drop time to simulate various grid conditions.
A Variety of
Built-in Programmable Features
PAS/PFV series has a number of
programmable features that can effectively and accurately simulate a variety of
power abnormal conditions or disturbance. Through the built-in step and gradual
mode, users can simulate voltage and frequency single-step or continuously
changes, such as voltage and frequency ramp up/ ramp down, instantaneous
changes, and so on. Phase angle and three phase independent adjustment function
can be used for simulating three phase imbalance and further test the
reliability of the EUT. With low voltage ride through and regenerative
function, PAS series is suitable for PV Inverter, Bi-directional EV charger,
Energy Storage System as an all purpose grid system simulator.
