With the development of the electric power system, static - state reactive power compensators ca n ' t have met the requirements of the actual production and operation, and the trend to the fast and dynamic compensation for reactive power become greater and greater. since ertan hydroplant and 500kv transmission systems in sichuan power system have been operated, many power plants of load center are forced to halt during the high - water period, because the great deal of power is transmitted to far - distance load center. thus the load center loses voltage sustentation and the level of the system stabilization is debased greatly
四川電網的二灘水電站和500kv輸變電系統投入運行后,由於二灘水電站的大量電力遠距離輸送至負荷中心,迫使負荷中心的火電機組在豐水期大量停機,使負荷中心失去電壓支撐,大大降低了電網的電壓穩定水平;同時,因為四川電網中的無功補償裝置全為靜態無功補償電容器(或電抗器) ,這些設備只能在系統正常運行狀態下起到無功補償和電壓支撐的作用,而在電網出現事故時,不但不能起到電壓支撐作用,反而會促使電網電壓崩潰事故的發生。Placing facilities for reactive power compensation can reduce network loss effectively as well as improve transmission capacity and regulate voltage profile
在配電系統中加裝無功補償設備,可達到降低網損的效果,此外還可以提高電網輸送能力和改善電壓質量。With the consideration of most of our transformers " taps are changed manually and some fluctuate unnecessarily, this paper presents a supervision system of oltc based on plc control technique. then we combine this system with reactive power compensate device such as shunt capacitor to design a new supervision system of substation voltage and reactive power synthetic control based on plc fieldbus
針對國內變電站電壓調整大多依靠人工調節,且有載調壓變壓器( oltc )分接頭動作頻繁的特點,本文提出了基於plc控制技術的有載調壓監控系統的研製方法,並以此監控系統為基礎,結合併聯補償電容器組等無功補償設備,設計了一種基於plc現場總線的變電站電壓無功監控系統。While with the super hige voltage power network gradually built and the structure of system becoming more complex, the calculation time of optimization increases when the number of buses that need reactive power compensation is relatively large. especially, when the positions of compensation are uncertain, selecting the position of compensation can reduce time when reactive power optimizing
而且隨著超高壓電網的逐步形成,系統結構日趨復雜,需要安裝無功補償設備的母線比較多的時候,優化計算所需的時間將加長;尤其是在網路補償位置不確定的情況下,無功補償點的選擇就成為無功優化計算前節約時間的有效措施。Using optimal power flow based spot price algorithm / software, the effect of the interruptible load management and the installation of shunt devices on handling the transmission congestion was analyzed, and then, an analysis was carried out in comparison with transmission congestion contract ( tcc ) based transmission congestion management strategy
