| 摘要: |
| 为了合理地计量谐波电能，提出了一种基于谐波功率分解的奖惩性电能计量方法。根据谐波电压、电流采样数据采用复线性最小二乘法估算谐波等值电路参数，然后通过谐波功率分解求解系统谐波功率和用户谐波功率，基于奖惩性计量模型即可得到奖惩性谐波功率。该方法考虑了公共连接点处谐波功率的分解，能够更合理地计量典型工况下的谐波功率。最后以IEEE14节点系统为例进行仿真分析，结果验证了所提方法的合理性和实用性。 |

| Abstract: |
| An incentive energy measurement method based on harmonic power decomposition strategy is proposed to measure the harmonic power reasonably. Harmonic equivalent circuit parameters are estimated by using complex least squares method based on the harmonic sampling data, then user harmonic power and network harmonic power are calculated by using power decomposition strategy, and the incentive harmonic power is obtained based on incentive measurement model. The harmonic power at PCC is measured more reasonably considering the power decomposition. Finally, the reasonability and practicality of the method are proved by the examples of IEEE 14-bus system. |
