| 中文摘要: |
| 过对常见的三相三线高压计量方式的23种错误接线进行理论分析，推导出一种新型差错电量退补公式。该公式可直接利用电能表在错误接线时所记录的正、反向有功和四象限无功电量，准确地计算出错误接线期间实际消耗的电量，避免了利用功率因数计算退补电量的更正系数法或比较法等传统退补方法，因一些退补因数难以确定而带来的退补误差。为了证明该方法的有效性，选取了几种错误接线在感、容性负载下进行了实验，实验结果进一步验证了采用该方法退补电量的准确性。与传统电量退补法相比，本方法具有更高的准确度和可靠性，并且实施简单。 |

| Based on the theoretical analysis of the 23 kinds of wiring error of the common three-phase three-wire high voltage measurements, a new method of error power compensation is deduced in this paper.The method can directly use the power meter record in the wiring error of positive and negative active power and reactive power of four-quadrant, accurately calculate the actual consumption of electricity during the wiring error, avoid using the power factor calculation compensating power correction coefficient method or comparison of traditional compensating method, because some compensating is difficult to determine the factor caused by the compensating error.In order to prove the validity of the method, several kinds of wiring error are selected to carry out the experiments under the condition of inductive and capacitive load.Compared with the traditional method, this method has higher accuracy and reliability and is easy to implement. |
