Abstract: with the "two nets" reform deeply and raise the level of power network operation, the concentration of distance monitoring, control of substation integrated automation system, can not only enhance the labor productivity, and reduce the possibility of human wrong operation. Substation integrated automation system can effectively improve labor productivity, the country is one of the development trend of network reconstruction, and to realize the modernization of the electric power production, scientific, information and the automation management to provide effective network information and accurate Numbers, for the safe and economic operation of power network provides an important basis. In this paper, the substation integrated automation system function and structure patterns are analyzed, and the integrated substation automation system of common problems are discussed.

引言
变电站是电力系统中的一个重要环节,它的运行情况直接影响到电力系统的可靠、经济运行.
随着自动化技术、通信技术、计算机和网络技术等高科技的飞速发展,通过变电站综合自动化系统内各设备间相互交换信息,数据共享,完成变电站运行监视和控制任务。变电站综合自动化系统大致有两方面的原则:一是中低压变电站采用自动化系统,以便更好地实施无人值班,达到减人增效的目的;二是对高压变电站(220kV及以上)的建设和设计来说,是要求用先进的控制方式,解决各专业在技术上分散、自成系统,重复投资,甚至影响运行可靠性。变电站综合自动化是提高变电站安全稳定运行水平、降低运行维护成本、提高经济效益、向用户提供高质量电能的一项重要技术措施。……
