摘要：
The shift towards more renewable energy sources and sustainable technologies has increased the interest in low-voltage DC grids. However, the definition of power quality issues in DC grids and related measurement techniques are still in their infancy. Consequently, standardization of DC electricity meter testing is not yet fully covering immunity to DC-grid-specific disturbances. Therefore, a new arbitrary-waveform testbed has been developed for testing of DC electricity meters in the presence of broadband disturbance signals with frequency components up to 150 kHz for DC voltage and current levels up to 1500 V and 600 A, respectively. The components of the testbed are calibrated and characterized, and a first demonstration of the complete setup was performed by testing a DC wideband precision power analyzer as an electricity meter. Apart from DC meter testing for customers, the testbed will be used for research to provide input for improved standardization.
