基于相对灵敏度确定电网电压稳定薄弱节点的研究

Research on Ensuring Weak Bus of Web Voltage Stability Based on Relative Sensitivity

定义了相对灵敏度,即在复杂系统中,保持负荷节点的功率因数不变,增加所有负荷节点的负荷,在同样负荷增长倍数时,节点的相对灵敏度最大的负荷节点是在这种负荷增长模式下的薄弱节点。仿真计算结果证明了该方法的准确性和有效性。

The relative sensitivity was defined.In the complex system, as keeping the power factor of the load bus from variation, increasing the load of all load bus and meanwhile at the same increased multiples, the bus of the maximal relative sensitivity is the weak bus in this load increasing mode. The simulation results expatiate both the validity and the effectiveness.
