摘　　要：采用基于广域测量系统(WAMS)的量测数据,提出基于范例推理(CBR)理论及功率振荡增量分布(OAPID)理论的互联电网区间模式振荡预警方法。该方法在系统未发生低频振荡时进行区间模式振荡预警;在系统发生振荡时提供系统运行方式的调整建议来改善系统阻尼。某区域电网WAMS实测数据的测试结果验证了所提方法的可行性和有效性。A method of inter-area mode oscillation prediction based on CBR（Case-Based Reasoning） theory and OAPID （Oscillatory Active Power Increment Distribution） theory is proposed for interconnected power grids,which,based on the measurements of WAMS（Wide Area Measurement System）,issues the warning of inter-area mode oscillation before low-frequency system oscillation occurs and provides the advice of system operating mode adjustment during system oscillation to improve system damping. Results of a test for a regional power grid according to its actual WAMS data demonstrate the feasibility and effectiveness of the proposed method.
