中文摘要：
励磁系统在源网协调运行中正发挥着越来越重要的作用，建立准确可靠的励磁系统模型是研究电网稳定性的基础，是稳定性结论真实可靠的必要保证，是制定合理的电网运行策略的重要条件。为了在BPA中研究发电机的稳定性，通过空载试验等现场实测的方法，获取发电机励磁系统的动态特性和模型特征。在励磁系统数学模型的基础上，通过建模仿真以及参数辨识的方法，建立了BPA可以调用的励磁系统模型，整定模型参数。通过BPA搭建了单机无穷大仿真模型，验证了模型的正确性。验证结果表明：整定模型与实际励磁系统具有相同的动态特性，为电力系统稳定性研究工作提供了真实可信的模型。
英文摘要：
The excitation system plays an increasingly important role in the coordinated operation of the sources and the power grid. The authentic simulation modeling of the excitation system is the foundation of researches on the stability of the grid, a necessary guarantee for the true and reliable conclusion of stability, and an important condition for power grid operation strategy. To study the stability of the generator in the BPA, the model characteristics and dynamics characteristics of the excitation system is obtained by using the no-load test and other field measurements. Based on the mathematical model of the excitation system, the excitation system model is built for the BPA by using modeling and parameter identification and the parameters are set accordingly. The correctness of this model is verified by the single machine infinite simulation model by means of the BPA. The results show that the tuning model and the actual system have the same dynamic characteristics and therefore an authentic model is provided for the studies on the power system stability.
