High Voltage Grid Simulator Adds PV Inverter’s HVRT Test Function

As photovoltaic industry policies continue its growing support for distributed solar power systems, commercial power generation equipment demands for 20kVA-100kVA inverters increase as well. With the development of grid-connected high-voltage 600Vac-800Vac (VLL) systems to reduce cost and increase power generation efficiency, an important challenge to manufacturers is the inverter’s stability in high-voltage grid connections. The newest high-voltage 1385Vac (VLL)/120kVA regenerative grid simulator released by Chroma meets the specifications for inverter quality verification and grid performance tests, such as LVRT, HVRT, harmonics, waveform distortion, 3-phase unbalance, voltage dips, short interruptions, and voltage change immunity tests.

mf00001048-01-en

61800_ac_load_4_tc

The latest UL1741 SA specification for inverter design must be able to run under HVRT test without off-line operation. In addition, it must have the capability to continuously adjust the power and infuse reactive current into the power system during high voltage ride through. So, when the inverter is designed for a normal rated voltage of 690Vac (VLL), it must be tested for rated grid voltage (over 897VLL) which is raised 1.3, 1.2, or 1.1 times respectively as it has to run uninterruptedly at dozens of test points during voltage rise and recovery. Moreover, it has to respond normally and issue a proportioned capacitive reactive current according to the standard during HVRT, which can effectively stabilized the grid voltage and ensure the demand for the quality of electricity.

Chroma’s high-voltage power grid simulator can output voltage up to 1385VLL (800VLN) without using a step up transformer. Besides up to 1.5V/us output voltage transient capability, it has flexible, cost-effective and space-saving features. For example, when testing an inverter below 50kVA, it can be used as two 60kVA power grid simulators; and if high power and high voltage 60-100kVA inverters are required for testing, two 60kVA power grid simulators can be connected in series for up to 1385VLL (800VLN).

New Regenerative AC Load Function – Further Extend the Grid Simulator Capability for Micro-grid Test Application

The Chroma 61800 Series high power regenerative grid simulator capable of delivering output power up to 300kVA has been widely used for testing PV inverters, power conditioning systems (PCS) and EVSE charging stations. Lately, more and more engineers are studying the applications of micro-grids and energy storage systems. The 61800 Series not only can simulate the voltage and frequency test requirements for different regions of world, it is also capable of simulating voltage transient and abnormal conditions with synthesis of harmonic / inter-harmonic components as well. Its full four quadrants operation capability and regenerative function used to feed the energy back to the grid are the most favored by users.

Aside from the aforementioned capabilities to simulate the AC voltage test conditions, the capabilities of simulating various load conditions in order to cope with the diversified and dynamic nature of the system are also required for the micro-grid testing. It is very rare in the market to have test equipment with both AC source and AC load functions as a single unit.

Traditional AC electronic load designs mainly consist of passive and switch devices. These electronics loads can only operate in the 1st quadrant (both voltage/current in the positive region) and 3rd quadrant (both voltage/current in the negative region). The functionalities for the traditional AC electronic load are mainly limited to CR mode and rectified mode due to the design’s nature. Unlike the traditional electronics load, Chroma 61800 Series with full four quadrants and a regenerative design has further extended its test application capabilities by including the regenerative AC load function as an option with its maximum loading capability equivalent to the maximum output power rating of the unit. For instance, with the AC load option installed, the 61800 Series is capable of providing up to 180kW loading capability.

The phase lead/lag mode with phase angle setting ranging from 90 degree ~ -90 degree will simulate the corresponding voltage and current condition under an inductive or capacitive type load (see below waveforms). When the phase angle setting is in the range of 90.1 degree ~ 180 degree (-90 degree ~ -180 degree), the 61800 will become a current source, similar to a programmable inverter which is applicable for micro-grid related testing.

61800_ac_load_3_en.jpg

The Chroma 61800 Series regenerative AC load function is applicable for AC power supplies, UPS, PCS and EVSE charging station (V2L/V2H) test applications. It can simulate the effects of different loading conditions based on various home appliances, or test the PV inverter’s power quality correction functionality by deliberately setting the AC load in various reactive load conditions. The regenerative AC load is applicable for simulating the various power flow conditions related to micro-grid application for research in smart management or for balancing supply and demand loads.

Chroma uses the DSP digital control method to add the optional AC load function to the 61800 Series regenerative grid simulator. The AC load function further diversified the 61800 Series test applications ranging from academic, R&D design verification, and quality assurance to mass production.

Chroma Launches Its New 63000 Series DC Electronic Loads to Satisfy the Tests for Small Power Supplies and Batteries

Chroma 63000

To meet the testing requirements of small power supplies, Chroma has launched a brand new 63000 Series of benchtop DC electronic loads specifically designed for testing lower power adaptors, cell phone chargers, small batteries (such as cell phone batteries), D/D converters, USB PD, and so on. Different from the modular electronic load, they can be used without a mainframe. With the advantages of its compact size, lighter weight, low cost, and portability, the 63000 Series is the perfect electronic load for R&D labs and colleges.

 Chroma 63000

The voltage and current specifications of each model in the 63000 Series are comprised of three settings and three measurement ranges. For adapters and USB PD’s that require higher testing accuracy, small current test like 0.1A is often performed during efficiency testing. However, misjudgment frequently occurs due to insufficient range or low accuracy. The minimum setting and measurement current range of the 63004-150-60 is 2A and the current error is less than 2mA which makes it suitable for these tests and validating the regulatory compliance of Energy Star. The maximum current output of a single load is up to 60A, with power up to 350W. Besides, the large scaled fonts and moderate shortcuts in its 3.5” LCD display bring great usability in the forms of sight and touch.

Chroma 63000 LCD screen

In addition to the basic CC, CR, CP, CV, and CRD modes, the 63000 Series also has battery discharge, User Defined Waveforms (UDW), and programming functions to satisfy the test requirements for D/D converters, 3C battery dischargers, and switching power supplies.

The battery discharge mode is applicable for 3C battery discharge test and can record the Wh (Watt) and Ah (Ah) during battery discharge. The User Defined Waveform (Figure 1) can simulate the real load current allowing the R&D test engineer to verify the power in the actual load current. The quality assurance department can reproduce the actual load current situation to reduce the development and validation time. For other DC power and component applications such as fuel cells, fuses, switches, and wiring tests, the pulse current (Figure 2) function is provided to test them by setting the repeat time to 1 in the existing dynamic loading mode.
