| description | With the emergence of “dual-high” characteristics in new power system, the wideband dynamic components in power grid have become increasingly complex, posing new demands and challenges for power and energy metrology technologies. The development of quantum power and energy standards represents the mainstream trend in quantum electrical metrology research. However, traditional differential sampling methods, widely used for transferring AC quantum voltage step waveform values, are limited within frequencies below 1 kHz to maintain a measurement accuracy at the 10-6 level. To address these issues, this paper proposes a wideband quantum power and energy standard design based on programmable Josephson voltage standard. By utilizing a wideband quantum differential measurement method based on the principle of sub-sampling, the precise traceability of wideband signals to low-frequency quantum voltage step uave is achieved, offering the potential to extend the quantum measurement frequency of power and energy from the current power frequency to beyond 10 kHz. An experimental system was constructed using the output of a pulse-driven AC Josephson voltage standard as the test signal. Preliminary results show that the sub-sampling method achieves a consistency of better than 3×10-6 with traditional differential measurement method at 1 kHz, and reveals no new obvious discrepancies when extending the frequency to 10 kHz. These findings provide essential technical support for the development of a wideband quantum power and energy standard with an optimal combined uncertainty at the 10-6 level. |
