摘　　要：提出了基于同步相量测量单元的预测型振荡解列方法。振荡中心两侧母线电压的相角差反映了功角差 ,利用该相角差的变化速度及符号 ,可以判定是同步振荡还是异步振荡以及滑差的情况 ,并实现预测解列功能。This paper proposes a predictive method for system separation control based on synchronized phasor measurements. The relative phase angles of the busses voltage reflect the change of relative power angles, so whether the system is in synchronous oscillation condition or in asynchronous oscillation condition can be identified and predictive system separation control can be applied,by the change speed and sign of relative phase angles. The main purpose of this paper is to analyze the relationship between relative phase angles and relative power angles.
