近日,南京南瑞继保电气有限公司成功中标威信电厂2×600 MW机组扭振保护(TSR)项目全部设备。威信电厂一期2×600 MW新建工程,是云南省滇东北地区的大型坑口火电厂,“云电外送”的主力电厂之一。威信电厂与溪洛渡直流工程的昭通换流站电气距离较近,存在次同步振荡及扭振的风险。次同步振荡及扭振是公认的电力系统复杂问题。扭振保护的特点是应用范围窄、技术含量高。南瑞继保公司研制的
Recently, Nanjing NARI Electric Co., Ltd. succeeded in bidding for all equipments of the 2 × 600MW unit torsional vibration protection (TSR) project of Weixin Power Plant. Weixin Power Plant a 2 × 600MW new construction project, Yunnan Province, northeast Yunnan is a large-scale power plant in Hang Hau, “cloud electricity to send” one of the main power plant. Weixin Power Plant and Xiluodu DC Project Zhaotong converter station electrical distance closer, there is the risk of sub-synchronous oscillation and torsional vibration. Subsynchronous oscillation and torsional vibration are recognized as complex electrical system problems. Torsional vibration protection is characterized by narrow application range and high technical content. NARI following the insurance company
