| 摘 要： | 提出了电力系统动态频率的新概念，阐述了电力系统的全系统动态频率、地区 系统动态频率、发电机动态频率以及电网中任意节点动态频率的涵义，分析了 传统“周期法”测量节点动态频率时不加任何辨识处理便试图用以表征发电机 动态频率、地区系统动态频率或全系统动态频率的局限性，并在此基础上给出 了新的动态频率测量算法，动模试验结果表明了所提算法的优越性。

| Abstract: | A new concept of dynamic frequency in power systems is proposed. An analysis of the classical periodic method for frequency calculation is given and some limitation are pointed out. After establishing a definition of dynamic frequency, a new algorithm for calculation of local system dynamic frequency is described. Measurement results of the new frequency measuring device confirm the applicability of the proposed approach. . |
