摘　　要：针对基于某运行点设计的飞轮储能系统(FESS)稳定器不能保证鲁棒性问题,提出考虑多种运行方式的FESS最佳安装地点、控制回路和反馈信号选择以及FESS稳定器参数整定的改进方法。在推导了含FESS的多机系统线性化模型的基础上,应用阻尼转矩分析法,将多种运行方式下的最小阻尼转矩指标中的最大值作为FESS安装地点、控制回路和反馈信号的选择指标,以改变特征值实部最小的运行方式作为整定FESS稳定器参数的运行方式,并以FESS接入四机系统为例,分析结果表明应用该方法设计的FESS稳定器在多种运行方式下都能有效抑制低频振荡,验证了方法的有效性,且具有一定的鲁棒性。For the issue of no guarantee of the robustness of the FESS（ Flywheel Energy Storage System）-based sta- bilizer designed at one of the typical operation, An improved method was proposed to select the best installing loca- tion, damping control loop, feedback signal robustly and to tune FESS-based stabilizer parameters by taking into account multiple operations. Based on linearized model with FESS and application of Damping Torque Analysis （DTA） , the maximum of all of the minimum Damping Torque Indices （DTI） under multi-operation conditions is the index of selection FESS installing location, damping control loop and feedback signal, and the operation of min- imum changing real of eigenvalue is the condition to tune FESS-based stabilizer parameters. And the results of a four-machine power system with FESS showed that power system oscillations are suppressed effectively by FESS- based stabilizer designed by the method under multiple operations. And also the results showed that the method pro- posed is effective and robust.
