        摘 要:介紹了某試驗變電站擬進行的各種試驗方式,對試驗站在公共連接點產生的電壓波動和閃變、有功沖擊進行了仿真計算,得出該試驗站需滿足國標關于電能質量限值要求的試驗容量為196 MVA,大于此容量則需要采用沖擊發電機進行試驗。建議試驗單位應與電網相關部門相互合作,采取相應措施,使試驗站沖擊負荷對電網的影響滿足國標限值要求。
        關鍵詞:試驗站;電壓波動;閃變;有功功率沖擊;電能質量

        Abstract: Introduction was made to various kinds of test methods planned for certain experiment station. This paper carried out simulation calculation for the voltage fluctuation, flicker and active power impact produced in the point of common coupling of experiment station, and obtained that the test capacity was 196 MVA, which was satisfied for national standard about power quality limiting value. If the capacity was larger than the value, the impulse generator would be used to carry out the experiment. It is suggested that the testing agency should cooperate with the relevant departments of power grid and adopt the corresponding measures to make the impact load of experiment station have little influence on power grid which meets the national limiting value.
        Key words: experiment station; voltage fluctuation; flickering; active power impact; power quality
