摘　　要：随着整个电网直流输电的逐渐增多,次同步振荡问题逐渐浮出水面,对机组轴系产生损伤,严重的可能引起机组轴系扭断、震荡失步、瓦解等重大事故,所以有必要对大型机组是否存在次同步振荡的可能性进行验证,以提高整个电力系统的安全可靠性。Along with the increasing of the whole DC （direct-current） power transmission grid, the problem of the subsynchronous oscillation has emerged gradually, which produces damage to unit＇s shaft system, the serious damage may cause the twist off, oscillation＇ s out of step, collapse and other major accidents of unit＇ s shaft system, so it is necessary to verify whether or not there is the possibility of subsynchronous oscillation in large unit in order to improve the reliability of the whole power system.

关 键 词：次同步振荡 直流输电 机组轴系
