| 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。 |

| Abstract: |
| 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. |
