摘要:電網(wǎng)自動電壓控制系統(tǒng)無效調(diào)節(jié),一方面增加了變電站一次設(shè)備維護成本,另一方面造成設(shè)備因動作次數(shù)超過系統(tǒng)設(shè)定的閉鎖值而閉鎖,導(dǎo)致電壓不合格時無設(shè)備可調(diào)節(jié),降低電壓合格率。通過對安順電網(wǎng)自動電壓控制系統(tǒng)的歷史調(diào)節(jié)情況進行統(tǒng)計、分析,找出造成無效調(diào)節(jié)次數(shù)多的原因,提出多種降低自動電壓控制系統(tǒng)無效調(diào)節(jié)次數(shù)的方法,并在實踐中驗證了方法的有效性。
關(guān)鍵詞:自動電壓控制;設(shè)備無效調(diào)節(jié);節(jié)能增效;精益管理
Abstract: The invalid adjustment of automatic voltage control system in power grid increases the maintenance costs of primary equipment in substations, furthermore, the primary equipment can't be used due to the exceeding number of adjustment, which decreases the voltage qualified rate. Through the statistics and analysis of past adjustment of automatic voltage control system in Anshun power grid, the reasons that cause invalid adjustment are found out, and various methods of reducing the number of invalid adjustment are put forward, and the effectiveness of the method is verified in practice.
Key words: Automatic voltage control; Invalid device adjustment;Energy saving; Lean management
