| 摘 要： | 非线性用户的增多,使电网中谐波含量不断增加,对电能准确计量带来较大影响。针对上述情况,首先叙述了谐波的主要来源,从计量仪表的频率特性曲线角度,分析了谐波条件下感应式电能表和电子式电能表的误差变化情况,指出现有计量方式的不足,提出了改进计量方式的措施。

| Abstract: | With nonlinear consumers increasing, the content of harmonic is becoming larger in an electric network. It hannes the power system and consumers. This paper first describes the origin of harmonic. Then the error caused by harmonic on induction watthour meter and electronic watthour meter is analyzed with the frequency curve of meter . The disadvantages of the present measurement models are pointed out. Finally, some methods are suggested to improve measurement. |
