摘要
低压限流控制能有效地改善直流系统故障后的恢复性能,其控制参数对系统的恢复特性具有明显影响.结合国内外对VDCOL的研究现状,对典型的VDCOL优化控制策略进行了分类和总结,阐述了各种优化控制策略的原理.介绍了多馈入直流协调恢复的影响因素,指出优化过程需要解决的两个基本问题,即各直流的VDCOL的特性和延迟时间常数.对VDCOL控制需要关注的问题和研究方向进行了探讨.
Abstract
The voltage dependent current order limiter (VDCOL) control can effectively improve DC system recovery performance after faults,amd its control parameters obviously influence the recovery features.In combination with the VDCOL research status worldwide,the typical optimization control strategies of VDCOL are classified and summarized,and their optimal control principles are expounded.The influencing factors of coordinated recovery of multi-infeed HVDC system are introduced.The optimization process needs to solve two basic problems,namely the characteristics of VDCOL and time-delay constant for various DC.Finally,some points and research direction are discussed for the VDCOL control.
