| 摘要: |
| 针对如何选择分布式潮流控制器(Distributed Power Flow Controller, DPFC)安装位置的问题，通过分析DPFC的运行原理，建立了DPFC的等效模型。然后以输电断面潮流分布均衡性和DPFC装置全寿命周期收益率为目标，提出了DPFC的优化配置模型。利用改进后的粒子群算法求解所提模型，能得到安装DPFC的最佳线路和输电断面潮流均衡度的提升率。通过IEEE39节点和某省级电网500 kV系统的仿真，结果证明DPFC装置能够重新均衡地分配断面联络线上的潮流，同样验证了等效模型和优化配置模型的合理性以及改进的粒子群算法的有效性。 |

| Abstract: |
| In order to solve the problem of how to choose the installation position of Distributed Power Flow Controller (DPFC), the equivalent model of DPFC is established after analyzing the running principle of distributed power flow controller. Then, the optimal allocation model of DPFC is based on the equilibrium of power flow distribution of transmission section and the life cycle return rate of DPFC. Using the improved particle swarm optimization algorithm to solve the proposed model, the DPFC can be installed on best lines and the increase of the rate of transmission section of the trend can be gotten. The simulation results of the IEEE39 nodes system and the provincial 500 kV system show that the DPFC device can reallocate the power flow on the cross-section connection line, and verify the rationality of the equivalent model and the optimal configuration model and the effectiveness of the improved particle swarm algorithm.
