摘　　要：本文针对当前电站动态过程在线预测难以实现的主要原因—计算精度和速度之间的矛盾,提出了一种新的工程解决方法。该方法将整个计算分为两部分:离线生成结果网部分和在线预测部分。离线部分求解微分方程生成结果供在线部分使用,从而使在线部分避开了耗时的微分方程求解。该方法可应用于同类的动态过程的在线预测问题。A new method used in engineering is brought forward to solve the contradiction between precision and speed of calculation which is the primary reason that the online prediction of transient process in power generating unit is difficult to be carried out. In this method, the total calculation is divided into two parts which are the offline part and the online part. In the offline part results of differential equation are prepared for the online part so that the time-consuming solving process is no longer be developed in the online part. The method can be applied to the similar problem of the online prediction for transient process.
