摘　　要：基于全系统的WAMS的实时测量数据和网络模型对发电机的暂态稳定轨迹进行准确预测,代替常规的时域仿真法,再对WAMS的轨迹预测结果采用PCOI映射:Rn→E(R1),进行IEEAC法等值。算例测试表明,将WAMS轨迹预测运用在IEEAC分析上,在保证预测轨迹准确的同时,可以正确地判断暂态稳定性,提高了IEEAC的计算效率。Based on the WAMS accurate and dense real-time data and network models of generators,this paper proposes a fast transient stability predicting method for transient stability track,instead of the conventional time-domain simulation method.And then it mapps the WAMS predicting results by PCOI methods to remain the characteristic of analyzing complex model and multiple-stability.The testing results show that the use of the WAMS forecast trajectory in IEEAC analysis can ensure the accuracy of the track,analyze the transient stability, and increase the computing efficiency as well.
