Abstract: At present, there are many problems in the traceability of digital energy meters. In view of this situation, this article describes a design method of an analog-digital hybrid standard energy meter, which makes the traceability of digital energy meters unified into the traditional analog traceability system. The article introduces the method of power angle self-compensation to improve the measurement accuracy of the power angle; through a series of technical measures, it overcomes the difficulty of the low sampling rate of 61850-9-2 digital message, making the standard table accuracy level reach 0.01,,which is of great significance for the verification work of the 0.05 class digital energy meter calibrator commonly used by power companies.
Key words : digital energy meter tracing,;integral algorithm;windowing function,;power angle self compensation

隨著智能變電站IEC61850數(shù)字化標(biāo)準(zhǔn)的推廣及相應(yīng)技術(shù)的發(fā)展,,數(shù)字化電能表應(yīng)用日益廣泛[1-2]。因此,,如何確立其檢定規(guī)范,、如何對其檢定標(biāo)準(zhǔn)進(jìn)行溯源等也就成了電力計量人員關(guān)心的問題[3-5]。現(xiàn)有對標(biāo)準(zhǔn)數(shù)字電能表的檢定僅僅是虛負(fù)荷情況下的校準(zhǔn),,因此無法對數(shù)字化電能表實現(xiàn)垂直計量,、溯源。由于模擬電能表計量檢測體系非常成熟,、規(guī)范,,如果能夠利用模擬量計量體系實現(xiàn)數(shù)字電能表檢測,則可以使數(shù)字電能表溯源統(tǒng)一到模擬溯源體系中,。
