【摘要】：電壓水平是衡量電能質(zhì)量的重要指標(biāo)。隨風(fēng)電場容量日益增加,風(fēng)電接入電網(wǎng)的規(guī)模不斷擴(kuò)大,風(fēng)電并網(wǎng)的電壓問題也逐漸暴露出來。文中利用電力系統(tǒng)分析綜合程序(power system analysis software package,PSASP),對不同運(yùn)行方式下的甘肅電網(wǎng)進(jìn)行了潮流計(jì)算,根據(jù)給出的電壓調(diào)節(jié)原則和手段對研究區(qū)域110 k V及以上等級越限母線電壓進(jìn)行了調(diào)節(jié)。在此基礎(chǔ)上,通過改變玉門地區(qū)風(fēng)電集群的有功出力研究了其對于系統(tǒng)靜態(tài)電壓的影響,并對出現(xiàn)這種影響的原因進(jìn)行了分析。
[Abstract]:Voltage level is an important index to measure power quality. With the increasing capacity of wind farm, the scale of wind power connected to power grid is expanding, and the voltage problem of wind power grid is gradually exposed. In this paper, the power flow of Gansu power network under different operation modes is calculated by using the power system analysis program (power system analysis software package / PSASP. According to the principle and means of voltage regulation, the overrun bus voltage of 110 kV and above in the study area is adjusted. On this basis, by changing the active power output of the wind power cluster in Yumen area, the influence on the static voltage of the system is studied, and the reasons for this influence are analyzed.
