Static simulation prediction method for rotating speed rising after load shedding of steam turbine

The invention relates to a static simulation prediction method for rotating speed rising after load shedding of a steam turbine. The technical scheme is as follows: a rotating speed rising value after load shedding of a unit is predicted in a static state or quantized values caused by valve jamming, over-standard closing time and the like to the rotating speed rising are evaluated to serve as related basis for evaluating dynamic characteristics of a regulating system; the rotating speed rising prediction value is high in accuracy, can be used for guiding power plant technicians to overhaul, and can also be used for evaluating the influence on the dynamic characteristics of the regulating system after equipment transformation, such as the influence on the rotating speed rising caused by high control valve replacement, valve closing time change and delay time tau; the method is an innovation of a rotating speed rising prediction method after steam turbine load shedding. 本发明涉及一种汽轮机甩负荷后转速飞升的静态仿真预测方法，其技术方案是，在静态下预测
