在电能计量工作中，能否正确选择与电力系统运行方式相匹配的计量方式是影响电能计量准确性的一个重要因素。根据电力系统中中性点接地运行方式的不同进行分类，分别对三相三线、三相四线两种计量方式在不同的中性点接地系统中计量的准确性、合理性进行理论计算和技术分析，为电能计量方案的制定提供一定的理论依据。

In the electric energy metering work, whether you can choose the correct matching power system is one of the important factors which will affect electric energy metering accuracy. In this paper, according to the different modes of neutral point grounding, we make theoreti-cal calculation and technical analysis on the measurement accuracy and rationality of three-phase three-wire measurement and three-phase four-wire measurement in different neutral point grounding systems, and provide certain theoretical basis for the formulation of metering schemes.
