摘　　要：在发电机及系统出现失步的情况下 ,利用失步保护装置 ,能够根据振荡中心的位置 ,有选择地解列电网中失去同步的部份 ,使机组和电网安全运行。文中介绍了失步保护判据的构成及发电机失步与构成判据的各阻抗轨迹之间的关系。最后着重介绍了失步保护的整定计算 ,为其在大机组上安全有效的运行提供了重要的理论依据。In case of the generator out-of-step with the system ,the fitted out-of-step protection device would operate to isolate the out-of-step section from the system selectively based on the position of oscillation center and to ensure the generation unit and power network operating safely. The criterion construction of the out-of-step protection and relationship between the out-of-step of the generator and each impedance locus that forms the criterion are presented in this paper. The setting calculation for the out-of-step protection is also given here which is an important basis in theory for its running safely and effectively in large generation unit.
