摘 要：介紹了某試驗(yàn)變電站擬進(jìn)行的各種試驗(yàn)方式，對(duì)試驗(yàn)站在公共連接點(diǎn)產(chǎn)生的電壓波動(dòng)和閃變、有功沖擊進(jìn)行了仿真計(jì)算，得出該試驗(yàn)站需滿(mǎn)足國(guó)標(biāo)關(guān)于電能質(zhì)量限值要求的試驗(yàn)容量為196 MVA，大于此容量則需要采用沖擊發(fā)電機(jī)進(jìn)行試驗(yàn)。建議試驗(yàn)單位應(yīng)與電網(wǎng)相關(guān)部門(mén)相互合作，采取相應(yīng)措施，使試驗(yàn)站沖擊負(fù)荷對(duì)電網(wǎng)的影響滿(mǎn)足國(guó)標(biāo)限值要求。
關(guān)鍵詞：試驗(yàn)站；電壓波動(dòng)；閃變；有功功率沖擊；電能質(zhì)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
