摘要
DPFC(分布式潮流控制器)能够改善电网潮流分布,解决潮流断面超限问题,提升电力系统承载能力。以DPFC的工程应用为出发点,阐述了DPFC的概念、技术原理及应用现状,梳理了DPFC装置投切方式、控制保护策略及工程应用的实现方式。指出未来DPFC的技术发展应突出装置分布式、控制集中式的特点,重点关注体积小型化、装置轻量化、模块可灵活组合等关键技术要点,以推动多元融合高弹性电网下的DPFC技术进步。
Distributed power flow controller(DPFC)can improve power flow distribution of the power grid,overcome power flow section excess,and enhance the bearing capacity of the power system.This paper expounds the concept,technical principle,and application status of DPFC based on its engineering application and sorts out the implementation mode of switching mode,control and protection strategy,and engineering application of DPFC;besides,it indicates that the future technical development of DPFC should be oriented to the distributed device and centralized control,and key technical essentials such as small size,lightweight and flexible module combinations must be focused to technical progress of DPFC under multi-convergence and the highly resilient power grid.
