电网失步解列装置配置研究

摘要

本文针对失步解列Ucosφ原理，研究了滇东北电网的振荡中心，论证了失步解列装置的配置方案，提出了失步解列的控制策略，仿真了牛从直流多极闭锁、甘永故障跳双回、永多故障跳双回的控制效果。研究成果于2014年6月得到现场应用。%Based on the out-of-step principle, this paper studies the oscillation center of Yunnan northeast power grid, discusses the configuration scheme of the out-of-step device, proposes a control strategy of the out-of-step, and simulation analysis the con￣trol effect of HVDC pole blocking or Ganding-Yongfeng N-2 or Yongfeng-duole fault N-2. It was applied on site in June 2014.
