数字化电能表脉冲接口设计对误差检测的影响

随着智能变电站的快速发展,数字化电能表的实际应用越来越广泛,数字化电能表的检测工作量也在逐步增大.目前,数字化电能表制造未实现标准化,各不同厂家生产的数字化电能表其脉冲接口设计存在一定差异,这些差异对数字化电能表的误差检测工作造成了影响.研究了数字化电能表误差检测的原理,针对几种不同型号的数字化电能表,对其脉冲接口设计的特点以及对误差检测的影响进行了探究.

With the rapid development of smart substation, digital input electricity meter has been widely applied. The work of measurement examination is gradually increasing. At present, the manufacturing of digital input electricity meter is not stand- ardized. There are some design differences on the pulse interface of digital input electricity meters from different manufactures. These differences may affect the measurement examination. The theory of measurement examination for digital input electricity meter is studied. According to several different models of digital input electricity meter, the characteristics of pulse interface design and the influences on error detection are discussed.
