Dewei Chuang Data acquisition system Application of PLC in islanding protection performance test of energy storage converter
Test equipment for anti islanding protection performance of energy storage converter meeting GB/T34133 standard
Anti islanding protection performance detection circuit
Island protection performance test Equipment used:
DEWE3-PA8
TRION3-1820-POWER-4
CT-1000
DEWE3-PA8 integrated host:
The integrated sensor power supply can be 8 Current sensor supply ； 4 pieces can be added TRION3 -1820-POWER-4 power acquisition card conducts 16 voltage and 16 current tests; The range of high-voltage channel can reach ± 2000Vpeak, and the range of current channel can reach 40Apeak; Test precision: DC ± 0.02% * reading ± 0.02% * range; AC 0.5~1kHz: ± 0.03% * reading without range error; There is no gap storage, and the signal waveform can be viewed without oscilloscope. CT-1000: DC/AC 1000A, basic accuracy:<0.05%
Test method for anti islanding protection performance: use waveform to record the changes of active power, reactive power and current when the switch is disconnected.
