Optional vac can save investment for the construction of the substation 選配vqc軟件,可節(jié)省變電站的投資。
Vqc vendor quality certification 售主質(zhì)量確認
It has been demonstrated that the new ipc - vqc system has preferable generalization and extension 模擬實驗運行表明該系統(tǒng)具有較好的通用性和可擴展性。
The techniques of a general electrical connection drawing system , flexible setup of input and output and automatic identification of substation running mode are also studied 現(xiàn)有的基于單片機開發(fā)的vqc系統(tǒng)無論在硬件上還是在軟件上都難以擴展,滿足不了今后電網(wǎng)自動化發(fā)展的需要。
With the development of substation automation and power system automation , especially the progress of voltage and reactive power centralized control in large - scale power system , the controllers of voltage and reactive power ( vqc ) for substation based on scm ( single chip microcomputer ) will not been adapted . this paper presents a new vqc application based on industrial pc 變電站綜合自動化、電網(wǎng)調(diào)度自動化和區(qū)域性電壓無功集中優(yōu)化控制的發(fā)展,以及近幾年城鄉(xiāng)電網(wǎng)改造中配置四臺主變壓器的大型變電站的出現(xiàn),都對變電站電壓無功綜合控制系統(tǒng)( vqc )提出了越來越高的要求。
