| 通过对油田配电网谐波源的调査和频谱分析,提出了一种基于网路结构的谐波集中治理方法。首先建立了系 统各次谐波的节点导纳矩阵,求解对应的灵敏度矩阵,并运用灵敏度矩阵寻找配电网中配置各次谐波滤波器的候选 位置。然后采用改进遗传算法对滤波器进行优化配置，在保证网络各节点谐波电压含量和总谐波畸变率符合谐波 标准以及滤波器安全可靠运行的前提下,使得全网滤波器的投资费用最少。实例分析结果表明，提出的无源滤波装 置的最优配置方法有效，给出的谐波治理方案能够有效地抑制网络中各节点谐波电压的畸变。 |

| Abstract: |
| A concentrated control method for harmonic based on network topology was presented by harmonic source investigation and spectral signature analysis to oilfield distribution netwoiic. First, the different order's harmonics nodal admittance matrix was established, and the corresponding sensitivity matrix was computed. The selected placement of different order's harmonic filters can be searched by the corresponding sensitivity matrix. Then the optimum placement of harmonic filters was determined by the improved adaptive genetic algorithm，while total investment cost is minimum with the satisfaction of harmonic voltage distortion limits and filter security constraints. The analysis results of example show that the optimum placement method of passive filter is effective and the harmonic control method can effectively suppress harmonic voltage distortion of distribution network. |
