中文摘要：
通过分析负荷节点和发电机节点参与因子的物理涵义．提出将参与因子应用于发电机出力调整方案以缓解电压紧张。该方法通过对未化简的雅可比矩阵进行模态分析求得参与因子，用参与因子指导发电机有功功率再调整；采用连续潮流法计算调整过程中系统运行状态的变化，以无功网损为间接指示指标来监视系统电压态势的改善情况。IEEE39节点系统的仿真结果验证了所提出的考虑机组参与因子的发电再调度方法可以一定程度地改善系统的电压态势，提高电压稳定裕度。
英文摘要：
The participation factors of load buses and generator buses are analyzed from their physical meaning and they are applied in the generation adjustment scheme to relax voltage tension. The participation factors are deduced from the unreduced Jacobian matrix by modal analysis to guide the readjustment of active power. Continuation power flow method is applied to calculate the change of operating states during adjustment and the reactive power loss is used as the indirect indication to monitor the improvement tendency of system voltage. The simulative results of IEEE 39-bus test system demonstrate that,the proposed strategy improves the voltage tendency and stability margin to a certain extent.
