介绍了影响大型隐极发电机进相运行深度的因素,分析了进相运行时电压变化对静稳边界、失磁阻抗圆的影响,提出了进相时欠励限制整定与失磁保护整定的配合原则,并通过分析现场实例给出工程应用的指导建议。
his paper discusses the factors that influence the phase-advancement operation of large non-salient pole generator. It is found that the generator voltage will change in phase-advancement operation, which affects the boundary of steady-sate stability and loss of excitation impedance circle. This paper studies the principle to harmonize the setting of low-excitation limited set with loss of excitation protection. Finally, some suggestions are made via several examples of field applications.
