摘　　要：为了满足电网调度人员实时了解电网电压运行情况的需要,开发了基于Web的电力系统电压稳定在线监控系统,该系统后台使用C++,Java等语言开发,前台使用extjs等脚本技术,数据库采用SQL server 2000。数据源来自EMS(能量管理系统)文本。开发过程使用MyEclipse 7.1工具。系统能够根据用户需求发布基态情况下和故障(N-1)情况下负荷裕度、区域裕度、裕度灵敏度等电压稳定分析数据,自定义参数进行预防控制。开发实例证明,采用Java,extjs技术开发可以提高系统开发效率,采用B/S模式加强系统的通用性,较好地满足电力系统电压稳定在线监控和分析的需求。In order to meet the needs of dispatching and monitoring the voltage stability of power grid in real-time,a monitoring system of voltage stability is designed based on Web.The programming of web in the server system is exploited by C＋＋,Java and so on,while the interface is exploited by the script technique,and the database management system is exploited by SQL server 2000.The data source comes from the EMS（electic management system） text.During the development process using the tools of Myeclipse,according to the need of users,the developmented system can release the voltage stability data in the state of normal or N-1 like the load margin,area margin,the sensitivity of load margin and so on.The example shows that the system designed with the technique of Java and Extjs can improve development efficiency,better the program universality and satisfy the demands of real-time monitoring and analyse voltage stability.
