Solar Array Simulator Model
The latest programmable solar array simulator power supply
62150H-600S&1000S released by Chroma provides simulation of Voc (open
circuit voltage) up to 1000V and Isc (short circuit current) up to 25A. The
62150H provides an industry leading power density in a small 3U high package.
The solar array simulator is highly stable and has a fast transient response
design, which are both advantageos to MPPT performance evaluation on PV inverter
devices.
The 62150H-600S/1000S has many unique advantages including high speed &
precision digitizing measurement circuits with a 100kHz A/D, 25kHz D/A
controlled I-V curve and a digital fi lter mechanism. It can simulate an I-V
curve accurately and clear the mains ripple effect from the PV inverter. In
addition, the built-in SAS I-V model in the standalone unit can easily program
the Voc, Isc, Vmp, and Imp parameters for I-V curve simulation, without a PC
controller.
The real solar array is influenced by various weather conditions such as
irradiation, temperature, rain and shade by trees or clouds, which will affect
the I-V curve output. The 62150H-600S/1000S is capable of storing up to 100 I-V
curves into the simulator memory, with a programmed time interval range of
1-15,000 seconds. It can simulate the I-V curve from the early morning to
nightfall for PV inverter testing or dynamic I-V curve transient testing. The
62150H-600S/1000S has a built-in 16 bit digital control and precision voltage
& current measurement circuits with a voltage accuracy of 0.05%+0.05%FS and
a current accuracy of 0.1%+0.1%F.S. It is ideal for real time MPPT analysis and
tracking monitoring for PV inverters through our soft panel. The user can also
enable the data recording function on the soft panel during the static MPPT
performance test.
When high power solar array simulation is required it is common to connect
two or more power modules in parallel. The 62150H-600S/ 1000S with a current
range up to 25A and a voltage range up to 1000V offers a high power density
envelope maximum of 15KW in a 3U package. It can easily parallel up to ten units
in a Master/Slave configuration to provide 150kW with current sharing and
synchronized control signals for commercial PV inverter (10kW 100kW)
testing. The 62000H series supplies have a smart Master/Slave control mode that
makes the parallel operation fast and simple. In this mode, the master scales
values and downloads data to slave units so that the programming is as simple as
using a standalone unit.
The 62000H series dc power supplies are very easy to operate from the front
panel keypad or from the remote controller via USB / RS232 / RS485 / APG
(standard) and GPIB & Ethernet (optional). Its compact size (3U) makes it
ideal for both benchtop and standard racking.
