AI Technical Summary
In outdoor operating environments, existing UHVDC shunts suffer from large measurement errors in resistance values due to temperature variations, and the current data acquisition is inaccurate, failing to effectively compensate for the temperature coefficient and affecting signal acquisition accuracy.
The method of multi-point temperature acquisition and real-time synchronous compensation is adopted. By setting a temperature acquisition module and a signal collection module in the shunt body, and combining them with the signal processing unit, multi-point sampling of current data and real-time synchronous analysis of temperature data are performed to generate the correspondence data between current and temperature, and comprehensive temperature compensation is performed.
It achieves consistent accuracy in current measurement over a wide temperature range, reduces current data acquisition errors caused by uneven manganese-copper resistance, and improves the reliability and stability of measurement.
