damped oscillation

基本解释

But power system interconnection has also brought a series of new issues to the operation, such as the possible negative or weakly damped oscillation, the reducement of security and stability levels, the emergence of stability weak links in the grid.
全國聯網在帶來巨大經濟利益的同時,也對電力系統運行帶來一系列的新問題,如多大區域電網聯網後,可能出現弱阻尼或負阻尼振蕩問題;電網互聯後,網架較薄弱的電網內部安全穩定水平有可能降低;多大區電網交流互聯後,存在一些電網穩定問題突出的薄弱環節,今年1月我國南方十幾個省市遭受數十年不遇的雪災,致使許多省份電網出現大麪積損燬,電力系統穩定性遭到極大破壞,最終導致大麪積停電。
