摘要
励磁控制对电力系统的静态、暂态、动态稳定有很大的影响,采用不同的励磁模型和参数进行计算可导致计算结果有较大的差异。在大量技术研究与工程实践的基础上,对发电机励磁系统的实测和建模进行了深入研究,将发电机励磁系统的实测建模经验进行了系统总结和提高,提出了一整套发电机励磁系统参数测试、稳定计算用励磁系统建模的方法,并在实际系统中验证了参数和模型的正确性。
The excitation control has a great influence on static, transient, dynamic stability of power system. Using the different excitation model and the parameters can lead to different results. Based on a lot of technical researeh and engineering practice, measm^ment and modeling of the generator excitation system are studied deeply. The paper summarizes and improves the measured modeling experience of generator excitation system, and puts forward a set of generator excitation system parameter test, stability calculation method for excitation system lnodeling. The parameters and model are verified in the actual system. The paper lays a good teehnieal foundation for improving the simulation accuracy of interconnected power grid, and transmission ability of power network.
