透平动态模型是动力系统动态模型中的一个重要组成部分。随着电力系统科学研究领域的扩大,特别是同步发电机的异步运行和再同期的研究,对透平动态模型提出了更高的要求。 本文在我校原有的透平模型基础上,从相似条件出发,研究了评价静态和动态模拟误差的方法。利用这方法,发现现有国内外所沿用的透平模拟方法存在较大的误差。因此文中提出了一些简便的并联校正措施,进而分析了它的线性化效果、稳定性、动态品质以及各参数间的相互关系,并且给出了相应的曲线。实验证明了该措施是有效的,而且在理论分析上也是正确的。
Turbine dynamic model is an important part of dynamical system dynamic model. With the expansion of the field of power system science research, especially the asynchronous operation of synchronous generators and the researches of the same period, the turbine dynamic model is put forward higher requirements. Based on the original turbine model of our university, this paper studies the methods of evaluating the static and dynamic simulation errors from the similar conditions. Using this method, it is found that the existing turbine simulation methods used in China and abroad have big errors. Therefore, some simple parallel calibration measures are proposed in this paper, and then its linearization effect, stability, dynamic quality and the relationship between the parameters are analyzed, and the corresponding curves are given. The experiment proves that the measure is effective, and it is also correct in theoretical analysis.
