Maintaining the balance between real-time generation and load is one of the important tasks of power system. Automatic generation control (AGC) is an important part of power grid frequency control, so grid-connected thermal power units must have good AGC performance. Many factors may cause the AGC regulation performance of generating units to fail to meet the requirements, such as unreasonable system design, imperfect control strategy, poor equipment characteristics and so on. This paper introduces the performance index of thermal power units participating in AGC regulation and analyses the influence of flow characteristics of steam turbine valves on AGC performance. By optimizing the steam turbine valve management function, the performance can be effectively improved. The effectiveness of this method is verified by its implementation on a typical 300 MW thermal power unit.
