Smart Inverter ATS
The Smart Inverter ATS is designed according to the specifications of various standards such as IEEE1547.1, EN50530, NB/T32004, CNS15382 and CNS15599., and has built in the test items into the system. The tests include the abnormal voltage and frequency test, synchronization test, open phase test, reconnect test and harmonics test. Preens PV Inverter ATS can test inverter’s input voltage up to 2000Vdc, grid tied voltage up to 600VL-L and output power up to 2000kW. Moreover, all test data are saved in the system for further analysis and comparison.
Smart Inverter ATS
The Smart Inverter ATS is a photovoltaic automatic test system launched by Preen lately can meet the electrical performance test of relevant grid-connected test standards such as IEEE1547.1, EN50530, NB/T32004, CNS15382 and CNS15599.
Independent setting for three phase high/low voltage ride through to simulate voltage surge and drop.
Low voltage ride through (LVRT) testing is necessary for testing the grid fault capability of power generation plants. It is one of the key test items to test the capability of electric generators, such as PV inverters, to stay connected in short periods of lower electric network voltage.
High voltage ride through (HVRT) testing is necessary for testing the grid fault capability of power generation plants. It is one of the key test items to test the capability of electric generators to stay connected in short periods of higher electric network voltage.
With its intuitive and graphic display, the main control system can show the present AC power, DC power and EUT’s testing status, and even continuously monitor and measure EUT's parameters and waveforms
Solar array simulation function is able to show multiple graphic displays on software panel. It can easily realize SAS mode and meet EN50530 standards requirements for static or dynamic MPPT test through simple parameter setting.
PAS series’harmonics waveform synthesis function allow user to program complex distorted harmonic waveform and generate up to 25 harmonics. It can simply set up voltage and adjust start phase of each step based on 50 or 60Hz fundamental frequency.
Islanding is resulted from abnormal frequencies and voltages and power quality issues when it is not under strict frequency control. Distributed generators must detect islanding and immediately disconnect from the circuit; referred to as anti-islanding. For this reason, solar inverters that are designed to supply power to the grid are generally required to have some sort of automatic anti-islanding circuitry. With our Smart Inverter test system software, it can easily simulate the occurrence of resonance*1 that lead to PAS gird simulator to disconnect with gird source to test whether the PV inverter is capable of promptly monitoring islanding situation and instantly cutting off from grid. The standard protection time is no less than 2s.
Smart Inverter test system can meet electrical performance test of relevant grid-connected test standards such as IEEE1547.1 / EN50530 / NB/32004 / CNS15382.
