一种基于热电变换的多次谐波电流溯源方法及系统
摘要：
本发明公开了一种基于热电变换的多次谐波电流溯源方法：输出间谐波和多次谐波电流和标准正弦电流；选择接入间谐波或多次谐波电流或标准正弦电流；将间谐波和多次谐波电流转换为间谐波和多次谐波电压，并将间谐波和多次谐波电压输入至交流/直流热电转换装置；将间谐波和多次谐波电压转换为第一直流电压，并测量出第一直流电压的第一电压值；通过高精度分流器将标准正弦电流转换为标准正弦电压，并将标准正弦电压输入至交流/直流热电转换装置；将标准正弦电压转换为第二直流电压，并测量出第二直流电压的第二电压值；比较第一电压值和第二电压值，获取与间谐波和多次谐波电流等效的标准正弦电流，实现间谐波和多次谐波电流向标准正弦电流的溯源。
摘要（英）：

The invention discloses a multi-harmonic current tracing method based on thermoelectricity transformations: outputting an inter-harmonic and multi-harmonic current and a standard sine current; selecting to access the inter-harmonic and multi-harmonic current or the standard sine current; converting the inter-harmonic and multi-harmonic current into an inter-harmonic and multi-harmonic voltage, andinputting the inter-harmonic and multi-harmonic voltage into an AC/DC thermoelectric converter; converting the inter-harmonic and multi-harmonic voltage into a first DC voltage, and measuring a firstvoltage value of the first DC voltage; using a high precision diverter to convert the standard sine current into a standard sine voltage, and inputting the standard sine voltage into the AC/DC thermoelectricity converter; converting the standard sine voltage into a second DC voltage, and measuring a second voltage value of the second DC voltage; comparing the first voltage value with the second voltage value, obtaining a standard sine current equivalent with the inter-harmonic and multi-harmonic current, thus realizing traceablility from the inter-harmonic and multi-harmonic current to the standard sine current.
