摘要
对三峡电站发电机采用的电力系统稳定器(PSS)对三峡电力系统动态稳定性的影响进行了分析和计算。以2010年的丰大、丰小、枯大、枯小四种基本潮流为主,计算了大干扰、小干扰时的系统稳定性。研究结果表明,三峡电站发电机无PSS时电力系统因阻尼不足会产生低频振荡,采用PSS可明显增强三峡电力系统的阻尼,提高系统的动态稳定性;三峡电站发电机采用PSS是必要的,可行的。
The influences of power system stabilizers (PSS) which are applied in the generator excitation control systems of Three Gorges Power Station on the dynamic stability of Three Gorges Power System are analyzed and calculated. Giving priority to the four basic power flows, i.e., the flood season large power flow, the flood season small power flow, the dry season large power flow and the dry season small power flow, the system stabilities under large disturbance and small disturbance are calculated. The research results show that when the PSS is not equipped, the damping of Three Gorges Power System will be insufficient and the low frequency oscillations will occur. Therefore, when the PSS are applied, the damping of Three Gorges Power System will be remarkably enhanced and the system stability will be improved, therefore, it is feasible and necessary to install PSS in Three Gorges Power Station.
