摘要
为适应智能变电站计量技术的发展,在新的技术条件基础上需有一套符合智能变电站特点的计量系统。结合电子式互感器输出信号特点及计量有关标准,着重讨论符合IEC 60044-7/8标准输入的模拟小信号电能表工作原理、性能特点和实际应用,论述了模拟小信号电能表检测系统和溯源方案,提出了一套模拟小信号电能表的现场考核系统。由于模拟小信号电能计量暂无国家标准和行业标准,随着智能变电站的大量投运,相关一系列建标工作即将开展。
In order to adapt to the development of metering technology in smart substation, it requires a set of measurement system which is consistent with the features of smart substation on the basis of new technical conditions. Combined with the characteristics of output signal of electronic transformer and the relevant standards of measurement, the working principle, per- formance characteristics and practical applications of the analog small - signal power meter are discussed in line with IEC 60044 - 7/8. The testing system and traceability program of analog small - signal power meter are also discussed, and a set of on - site assessment system for the analog small - signal power meter is proposed. Since there are no national standards and in- dustry standards for the analog small - signal power metering, establishing the relevant standards will be carried out along with smart substation being put into operation.
