摘要
现有系统仿真软件一般认为,在暂态过程中,火电厂的出力是不变的,把锅炉、汽轮机等的动态过程做简单的线性处理,而慢动态的存在可能是导致系统发生中长期失稳的重要原因.根据当代火力发电设备的特点,得到比较详细的火电单元机组及其控制系统的模型,并在电力系统分析综合程序中进行了自定义建模和系统仿真.
The existing system simulation software thinks that the output of thermal power plant is constant in the transient process, and the turbine, boiler and other dynamic processes are linearly done, meanwhile the existing of slow dynamics may be the important reason of long-term instability on power system. Based on the characteristics of modern thermal power generation equipment, a more detailed thermal power unit and its control system model are obtained, and a custom modeling and system simulation is finished in the power system analytic program.
