摘　　要：ＥＥＡＣ算法是目前国际上唯一能满足在线实时要求，具有定量性、快速性的电力系统暂态稳定分析方法。 ＥＥＡＣ在线软件包在东北电网中经过５年在线运行，获得了用户的信任和认可，也从用户的反馈中积累了丰富的经验，从算法到工程实施都得到了不断改进。文中介绍了其在ＣＣ２０００开放式 ＥＭＳ环境中的在线实时环境、数据流，以及为调度人员使用方便而在程序运行模式、人机界面等方面进行的工程考虑，并给出了计算精度、误差分布、计算速度等统计结果和实际工况单相重合闸操作的整定计算实例。EEAC method, has high-speed and quantitative characteristics. is the unique transient stability analysis method which can meet the requirement of on-line real-time application in the EMS in the world for power system. EEAC on-line software package has won users' trust and approval and is being improved continually from algorithm to engineering practice by the accumulation of experience from users' feedback, since it has been put into on-line operation in Northeast China Power System for five years. The on-line real-time environment and data flow of EEAC method in the CC2000open environment of EMS are introduced. Some engineering considerations, such as the program operation model and man-machine interface. are presented to give the dispatchers convenience. The statistical results of calculation precision. error distribution, calculation speed and so on are given. A real case about the adjustment calculation of single earth fault and re-close operation is also given.
