摘要:隨著社會經(jīng)濟的發(fā)展，城鄉(xiāng)電網(wǎng)規(guī)模不斷擴大，電網(wǎng)結(jié)構(gòu)日趨復(fù)雜，特別是目前我國的電力工業(yè)已經(jīng)開始進入“大電網(wǎng)”、“大機組”、“超高壓交、直流輸電”、“電網(wǎng)調(diào)度自動化”、“狀態(tài)檢修”等新技術(shù)發(fā)展的新階段，這對供電可靠性的要求越來越高。備用電源自動投入裝置對提高供電的可靠性和連續(xù)性起著非常重要的作用，因此備自投在系統(tǒng)中得到廣泛的應(yīng)用。但其原理較為簡單，在某些特殊情況下，造成備自投裝置不能正常動作。譬如，目前的備用電源自動投入裝置普遍不能與安穩(wěn)系統(tǒng)配合，需要把備用電源自動投入裝置退出運行，嚴重的降低了電網(wǎng)的供電可靠性?，F(xiàn)針對電力系統(tǒng)中備自投裝置存在的問題進行總結(jié)，提出各問題的改進方法。通過對備自投進行改進、升級，使其變成智能化的備自投系統(tǒng)，能根據(jù)故障的特點分析出故障區(qū)，從而直接對故障區(qū)動作，保證了動作的準確性、提高備自投的成功率，減少停電范圍，恢復(fù)對無故障區(qū)設(shè)備進行供電，保證了對用戶的供電連續(xù)性，對提高供電可靠性、電網(wǎng)的安全運行有著重要的意義。因此，在生產(chǎn)管理工作中，對備自投裝置的認識和管理不容忽視，只有正確使用和保護好它，我們的供電可靠性才能得到足夠的保證，人民的生活和社會的健康發(fā)展才能得到保障。 關(guān)鍵詞：備自投；動作；成功率；供電
Abstract:With the rapid development of China’s economy, the power grip systems in both urban and suburban area keep growing larger in scale and more complicated. The current situation of China’s electricity industry is gradually entering a new stage with the advanced technology of “large high voltage electric system, large generating set, high voltage DC/AC electricity transmission, dispatching automation, state maintenance”. Thus a more reliable power grip system is required. Standby power source automatic put-in device is therefore widely used for it is a key element to ensure a reliable and continuous electricity transmission. However, with a relatively simple principle, the standby power source automatic put-in device may not work properly under certain circumstances. For example, the existing standby power source automatic put-in device generally can’t work well with a stable system, it has to be quitted from the system, which will reduce the stability of electricity generating to a large extent. The thesis is going to summarize the problems in the application of the standby power source automatic put-in device in power grip system as well as to suggest better solutions. By improving the standby power source automatic put-in device to an intelligent system, we can find out the trouble zone instantly according to features of the breakdown. In a result, the goals of ensuring the preciseness and high success rate of the standby power source automatic put-in device system, reducing the electricity breakdown area, restoring power supply for trouble-free area and stabilizing the electricity transmission are achieved. Therefore, it is of great significance for improving the reliability of electricity transmitting as well as building a safer power grid system.Therefore, during production and management, we should not neglect the recognition and management of standby power source automatic put-in device. Only if we use and protect it in a correct way, we can secure the stability of electricity generating, as well as people’s living and stable development of society.
