摘　　要：为理解和解决电力系统的低频振荡问题,结合川渝并入华中电网互联输电的实际工程,基于低频振荡故障的数学模型和机理的研究,计算分析了目前华中电网产生低频振荡的几率、地点和稳定特性。利用实时数字仿真系统(RTDS)搭建大区电网等值简化模型,并利用RTDS和电力系统综合程序(PSASP)对电力系统中常见的抑制低频振荡故障方式进行计算分析和比较,总结出有关规律以进一步研究和抑制全国联网后可能伴随的低频振荡。As the rapid development of power industry, the scale of the power system becomes larger and larger. Thus, the low frequency oscillation of large-scale internet system has badly endangered the secure operation of the system. This paper combines actual transmit electricity item of central China grid to study mechanism of low frequency oscillations. Basing on RTDS and PSASP, through calculating central China grid, the paper analyzes stabilization and occurrance rate of low frequency oscillation, compares effects of some control methods in power system, educes some valuable conclusion which is useful to restrain and study the low frequency oscillation of power system after large area power system interconnection.
