    摘 要: 介紹了風(fēng)電場接入電網(wǎng)運行后對電力系統(tǒng)穩(wěn)定性的影響。結(jié)合三門峽地區(qū)電網(wǎng)的實際情況,在具體算例數(shù)據(jù)的基礎(chǔ)上建立相關(guān)系統(tǒng)元件的數(shù)學(xué)模型,采用模型仿真與數(shù)據(jù)分析相結(jié)合的方法對含雙饋風(fēng)電機組風(fēng)水電聯(lián)合系統(tǒng)的穩(wěn)定性進行了研究。結(jié)果表明雙饋風(fēng)電機組的接入降低了系統(tǒng)原有的阻尼,為系統(tǒng)引入了相關(guān)的振蕩模態(tài),分析研究成果對三門峽地區(qū)電網(wǎng)調(diào)度運行具有指導(dǎo)意義。

    Abstract: Introduction was made to the impact on power system stability after wind farm connection to power grid operation. Combined with actual situation of Sanmenxia area grid, this paper established the relevant system element mathematical model based on specific calculation example data. The model simulation was combined with data analysis to research on the stability of wind-hydroelectric combined system with doubly-fed wind generator unit. The result shows that connection-in of double-fed wind generator unit has reduced original damping of power system and introduces related oscillation mode for the system. The analysis study achievement has guiding significance for Sanmenxia area grid dispatching.
               Key words: doubly-fed wind generator unit; hydro-generator unit; stability of power system; oscillation mode; Prony algorithm
