摘要
提出了一种更加符合电力系统机电暂态过程的全过程系统振荡模式的设计思想。通过对振荡中系统频率的正确理解 ,提出了利用多项式拟合系统频率变化速度的新思想。系统振荡中的各种关键参数均可设定 ,可为振荡中各种继电保护装置和安全自动装置的动作行为评估提供足够的典型数据。最后 。
A design concept for the complete power system oscillation simulation is proposed. Based on the investigation of frequency variations during the transient process, polynomials are suggested to match the variations. Thus, the key parameters of power system oscillation can be set to provide enough typical data for the evaluations of the behaviors of all types of relays and security automatic devices. This method is validated by Electromagnetic Transits Program (EMTP).
