摘要
对怒江电网高频切机动作后可能出现的问题进行分析,并结合该电网内水轮发电机组构成情况,对水斗式水轮发电机组折向器应用功能进行研究,提出切实可行的解决方法,对怒江电网联络线故障跳闸后的独立电网安全、稳定运行具有十分重要的意义。
The possible problems after the over frequency generator tripping of Nujiang power grid are analyzed. Taking the composition of hydro-generator-units in Nujiang power grid into account, the applications and effectiveness of the jet deflectors on pelton-type hydro-generators units are studied. The solutions based on the jet deflectors for frequency rising, without over frequency generator tripping, of the Nujiang isolated grid after the tripping out of interconnection line between Nujiang power grid and the main grid of Yunnan province caused by faults are proposed, which are of great significance to the secure and stable operation of Nujiang power grid.
