| 摘 要： | 超高压电网振荡模型的准确设计是进行振荡与故障识别算法研究的前提。提出并论证了超高压电网振荡频率变化连续且可导原理,设计出具有连续可导性质的电网振荡频率函数,重新设计了振荡初始与复归阶段的频率变化函数,尤其在振荡复归阶段,使用具有衰减特性的反双曲函数来模拟振荡频率逐步衰减,直至恢复正常的过程。通过典型算例验证了该新模型的有效性。

| Abstract: | A new design concept that both the oscillation frequency function and its derivation should be continuous is proposed.Based on this principle and the investigation of frequency variations during the transient process,the frequency diversification function during start-up stage and recover stage is reconsidered,especially that a negative-double-curve function with the attenuation characteristic is utilized to construct the frequency function of the recover stage.The oscillation frequency simulation is validated during some typical experiment. |
