【摘要】 为了提高终端用户配电运行的可靠性和供电电能质量的稳定性,本文在传统低压终端配电自动化方案的基础上提出了一种电能质量集散控制系统方案。该控制系统的集中控制部分不仅继承了传统配电自动化的功能,而且将传统被动的电能质量监测分析功能增强为主动的电能质量控制功能。分散控制部分由若干个电力电子装置子模块组成(集成在标准的抽屉式开关柜中),不仅能在终端处削弱负荷间的电能质量影响,而且也能治理电网入口处的电能质量。最后实验数据证明所提方案是可行的。更多还原

【Abstract】 In order to improve the reliability of terminal distribution network and the stability of power quality, this paper proposes a kind of distributed control system scheme about power quality on the basis of traditional LV distribution automation system scheme. The central control part of the control system not only inherits the function of traditional distribution automation, but also enhances the traditional power quality monitoring and analysis functions to active power quality control function. The decentralized control part, which consists of a number of power electronic device module integrated in the drawer of standard draw-out type switchgear, can solve the power quality problems in the vicinity of the nonlinear loads. Power quality at the entrance of power grid is improved, and the power quality impacts of loads can be weakened. The experiment proves that the method is feasible.更多还原
