【摘要】：电力需求的持续增长、传统能源紧缺形势不断加深,以及环境问题的日益突出,分布式电源尤其是可再生能源发电技术的发展获得了广泛支持。主动配电网的出现是为了加大配电网对于可再生能源的接纳能力,随着分布式电源越来越多的引入配电网,在缓解电网压力的同时也引入了大量谐波。本文就主动配电网中分布式电源这一谐波源分布较多的情况,提出采用电力滤波器综合配置的方法进行主动配电网谐波综合治理。文中首先分析了适用于主动配电网的无源电力滤波器的优化配置法,包括无源电力滤波器最佳位置配置法与参数优化设计法。文中采用网络固有结构法来确定无源电力滤波器最佳配置位置候选节点,考虑到实用性,采用传统经验法确定无源电力滤波器的具体参数。接着分析了有源电力滤波器的优化配置方法,选定易于理解的分步规划法。最后,提出主动配电网电力滤波器综合配置法,对谐波进行分层治理,第一层采用无源电力滤波器治理含量较多的谐波次数,第二层采用有源电力滤波器进一步改善性能。仿真算例表明,本文提出的主动配电网电力滤波器综合配置法能够有效治理主动配电网中的谐波,在保证各节点谐波电压含有率和电压总谐波畸变率全部达标的基础之上,让主动配电网的谐波综合治理方案满足一定的经济性。
[Abstract]:The increasing electricity demand, the traditional energy shortage situation continues to deepen, and environmental issues have become increasingly prominent, especially the development of distributed power and renewable energy power generation technology has gained wide support. Active distribution network in order to increase the acceptance ability of distribution network for renewable energy sources, with the introduction of the distributed power distribution network in more and more. Relieving the pressure of power network also introduced a large number of harmonics. The active distribution network in distributed power the harmonic distribution of more, the paper puts forward the method of comprehensive configuration of active power filter harmonic distribution network comprehensive management. This paper analyzes the optimal allocation method of passive power filter for active distribution network, including the best position of passive power filter configuration method and parameter optimization method. The method to determine the network structure inherent source Optimal placement of power filter candidate nodes, considering the practicality, the traditional method to determine the specific parameters of passive power filter. Then analyzes the optimal allocation method of active power filter, the selected step programming method is easy to understand. Finally, the active power filter with integrated configuration method of power grid, hierarchical governance of harmonics, the first layer the number of passive power filter harmonic governance more content, the second layer adopts active power filter to further improve the performance. The simulation example shows that the proposed active distribution network power filter comprehensive configuration method can effectively control the harmonic active power distribution network, the harmonic voltage of each node containing the base rate and the total harmonic distortion of voltage ratio standard, make comprehensive treatment scheme of harmonic active distribution network to meet certain economic value.
