摘　　要：在暂态稳定仿真中利用PMU(phasor measurement unit)实测信息,可以提高仿真的计算速度和精度。基于传统的交替迭代法,提出了2种结合PMU信息进行暂态稳定仿真的方法。研究表明:用PMU信息能够减少需要求解的系统的微分代数方程组,从而减小仿真计算的规模。所提方法在New England 10机39节点系统和IEEE 50机145节点系统上进行了测试,并与传统方法作了对比。对动态模型参数与实际不符及PMU有测量误差的情况进行了模拟和讨论。仿真结果验证了方法的有效性。Incorporating the PMU measurements information in transient stab computing speed and enhance accuracy in the time-domain simulation. Based on iteration technique, this paper presents two simulation methods combined w y simulation can increase e conventional alternating the PMU measurements information, in which the number of differential-algebraic equations is reduced and so is the computational scale. The proposed methods have been tested and compared with the conventional method using the New England 10-machine 39-bus system and IEEE 50-machine 145-bus system. The cases with errors of the dynamic model parameter and PMU have been also simulated and discussed. The simulation results demonstrate the effectiveness of the presented methods.
