云南昭通地处云南东北部，其电网与云南主网联系较薄弱，大机小网问题比较突出。当甘顶－永丰－多乐500 kV线路N－2后系统阻尼很弱，通过优化溪洛渡机组PSS参数，提高了N－2后系统阻尼，提高了电网稳定性。
雲南昭通地處雲南東北部，其電網與雲南主網聯繫較薄弱，大機小網問題比較突齣。噹甘頂－永豐－多樂500 kV線路N－2後繫統阻尼很弱，通過優化溪洛渡機組PSS參數，提高瞭N－2後繫統阻尼，提高瞭電網穩定性。
운남소통지처운남동북부，기전망여운남주망련계교박약，대궤소망문제비교돌출。당감정－영봉－다악500 kV선로N－2후계통조니흔약，통과우화계락도궤조PSS삼수，제고료N－2후계통조니，제고료전망은정성。
Zhaotong city locates in the north east of Yunnam Province.Zhaotong power grid connects to Yunnan power grid weakly, and problems of small power system containing large capacity generators is serious.The system damping is small while Ganding to Yongfeng and Yongfeng to Doule 500 kV double-circuit Line are faulted.The system damping and stability are improved by optimi-zing PSS parameters of Xiloudu hydropower station.
