摘要
鉴于参数敏感性分析是水轮机调节系统稳定性研究的重要内容,以XLD电站中某机组的孤网运行模式为例,基于轨迹灵敏度指标,在机组负载扰动和参数摄动条件下研究了系统主要变量对参数变化的敏感程度。结果表明,孤网模式下不同参数变化对不同变量的影响不同,系统变量对发电机参数的敏感性要大于对随动系统参数的敏感性。
Parameter sensitivity analysis is an important part of the stability study of hydro-turbine regulation systems.Taking the isolated grid operation mode of a unit in XLD power station as an example,the sensitivity of the main variables of the system to parameter changes is studied based on the trajectory sensitivity index under load disturbance and parameter perturbation of the unit.The results show that different parameter changes have different impacts on different variables in isolated grid mode,and the sensitivity of system variables to generator parameters is greater than that of servo-system parameters.
