【摘要】 本文通过 PSASP 对某实际电网有功脱落后的动态频率进行了仿真,指出 PSASP 中发电机模型的惯性时间常数比实际电网运行时的发电机的惯性时间常数偏小。通过改变发电机仿真模型的惯性时间常数,分析了惯性时间常数对电力系统动态频率的影响,并通过调节发电机模型的惯性时间常数,得出了与实际电网相吻合的动态频率仿真曲线。更多还原

【Abstract】 Using PSASP the simulation of dynamic frequency for one real power network in active power tripping status is introduced in this paper,by analysis,it points out that the inertia constants of synchronous models in PSASP is smaller than the ones in real power networks.With the changing of inertia constants of synchronous models in PSASP,the influence of inertia constant to power systems’ dynamic frequency is analyzed.The simulation curve of dynamic frequency that meets the dynamic frequency of real power networks is got by inertia constant adjustment.更多还原
