摘要
结合混流式水轮机及引水系统结构和工作特点,构建了更接近于真实系统的水轮机及引水系统仿真模型。将新模型应用于某180 MW水轮机调速系统参数测试工作中,辨识了水轮机及引水系统模型及调速系统参数,并进行了频率扰动下的仿真校核,验证了新模型参数的精确性、可靠性。
According to the structure and characteristics of radial- axial flow bydroturbire and diuerison system, a new model was established, which was used in theparameter testing work of a 180 MW hydro-turbine and its speed control system. Afteridentifying the parameters of hydro- turbine and its water diversion system amd speedcontrol system,the simulation tests were conducted under frequency fluctuation. The resultshowed that the accuracy and reliability of the new model parameters.
