摘 要：介紹了某特高壓變電站站用交流系統和高壓站用變有載調壓原理，闡述了一起高壓站用變異常調壓現象，分析了其產生原因，并給出了5 種改進措施。指出當站外備用電源電壓超出合格范圍后，還是無法進行電壓控制，只能使備用電源對側站盡量確保相關35 kV 母線電壓在合格范圍內，或者將本站0號站用變改造成有載調壓方式。
關鍵詞：站用變；有載調壓；特高壓變電站

Abstract: This paper introduced the principle of on-load voltage regulation for the AC system and high voltage station of certain UHV substation, expounded a case of abnormal voltage regulation phenomenon in high voltage station, analyzed the produced reason and gave five kinds of improved measures. It is pointed out that after the standby power supply voltage outside the station exceeds the qualified range, the voltage control cannot be performed. It is only possible to make the standby power supply side station try to ensure that the relevant 35 kV bus voltage is within the qualified range, or changes No. 0 station in home station into an on-load voltage regulation mode.
Key words: station variable; on-load voltage regulation; UHV substation
