    摘要:

    针对配电网中引入大量分布式电源后运行特性和无功电压特性与传统配电网的显著差别,提出了基于配电自动化系统的主动配电网自动电压控制系统架构。以馈线实时拓扑连接为基础,提出以无功可调设备为控制对象的自治控制区域划分方法。设计了以自治控制区域作为控制单元的电压无功控制策略,包括电压控制分区策略、电压越限控制策略、馈线无功越限控制策略及与其他系统的协调控制策略和安全闭锁策略,并给出了主动配电网自动电压控制系统的整体流程。结合实际案例验证了文中所述主动配电网自动电压控制系统架构是一种在配电自动化系统层面进行电压无功控制的有益探索。

    Abstract:

    Aiming at the significant differences between operating characteristics, reactive voltage characteristics and traditional distribution networks after the introduction of a large number of distributed power sources in the distribution network, an automatic voltage control system architecture of active distribution network based on distribution automation system is proposed. Based on the real-time topology connection of feeders, an autonomous control region division method with reactive power adjustable device as the control object is proposed, including: voltage control partition strategy, voltage over-limit control strategy, feeder reactive over-limit control strategy, coordinated control strategy with other systems and safety blocking strategy. Then, a voltage and reactive power control strategy based on autonomous control region is designed, and the overall flow of the automatic voltage control system for distribution network is given. Finally, combined with the actual case, the active distribution network automatic voltage control system architecture described in this paper is a useful exploration of voltage reactive power control at the level of distribution automation system.
