中文摘要：
电力系统负荷的时变性和随机性给实时或超实时暂态稳定分析带来了困难。提出一种可用于实时或超实时暂态稳定分析的快速负荷建模方法，为解决这一难题提出了新思路。该方法以实时辨识、实时使用为主要思想，采用强跟踪滤波器进行暂态稳定分析的快速负荷建模，并用辨识结果实时更新超实时暂态稳定程序中的负荷模型。仿真结果表明，所提出的快速负荷建模方法能够满足暂态稳定分析对负荷建模的实时或超实时需求。
英文摘要：
The time-variation and randomness of load in a power system is a big problem for the real-time or faster-than-real- time analysis of transient stability. A fast load modeling method for the real-time or faster-than-real-time transient stability analysis is presented. The principal idea of the method is ＂real-time identifying and real-time applying＂. A strong tracking filter （STF） is used in identifying the key parameters of the load model in real-time. Then the identified parameters are instantly applied in the real-time transient stability analysis. Simulation results demonstrate that the method proposed can meet the need of real-time transient stability analysis in terms of not only accuracy but also the calculating speed.
