论文摘要
我们提出了第一个解决方案，以估算具有有损传输线的多支电源系统状态。我们考虑了电力系统的经典三维\ FluxDecay”模型，并假设每个发电机的主动和反应性以及转子角度和激发电压可用于测量|与当前技术可行的场景。观察者的最新开发人员的最新方法与参数估算的最新方法有关：参数估算的最新估计以及问题的估计问题，以及参数估计的问题，该方法的问题是问题的问题，并且是参数估算的问题，该方法是问题的问题。将这些参数估算的技术都可以克服缺乏持续的激发的问题，这阻碍了标准观察者设计的应用。
We present the first solution to the problem of estimation of the state of multimachine power systems with lossy transmission lines. We consider the classical three-dimensional \fluxdecay" model of the power system and assume that the active and reactive power as well as the rotor angle and excitation voltage at each generator is available for measurement|a scenario that is feasible with current technology. The design of the observer relies on two recent developments proposed by the authors: a parameter estimation based approach to the problem of state estimation and the use of the dynamic regressor extension and mixing technique to estimate these parameters. Thanks to the combination of these techniques it is possible to overcome the problem of lack of persistent excitation that stymies the application of standard observer designs. Simulation results illustrate the performance of the proposed observer.
