| 摘要: |
| 暂态电压稳定问题对系统安全稳定运行提出了严峻挑战，研究一种量化评估实际系统暂态电压稳定性的方法具有重要意义。在电力行业标准中大扰动情况下暂态电压稳定判据的基础上提出电压暂降指标，包括电压暂降严重性指标和电压合格性指标，涉及单一故障下节点电压暂降指标、多故障集下节点电压暂降指标以及系统电压暂降指标，并以此评估实际电网中任意节点或整个系统的暂态电压稳定性。算例分析采用广州电网2016年规划数据，利用PSD-BPA进行时域仿真，仿真分析结果体现了故障类型、负荷模型对暂态电压稳定性的影响，及所提指标用于量化评估实际系统暂态电压稳定性的直观性与有效性。 |

| Abstract: |
| Since the transient voltage stability presents great challenge to the safe and stable operation of system，it is of great significance to research the quantitative assessment method for the transient voltage stability of actual system. The voltage sag indexes，including the voltage sag severity index and the voltage sag eligibility index，are proposed based on the transient voltage stability criteria stipulated in electric power industry standard for large disturbance conditions. Classified into single-fault one-node voltage sag index，multi-fault one-node voltage sag index and system voltage sag index，they are applied to assess the transient voltage stability of any node or whole system for actual power grid. Case analysis adopts the data planned for 2016’ Guangzhou Power Grid and applies the PSD-BPA time domain simulation. The simulative results show the impacts of fault type and load model on the transient voltage stability，as well as the intuition and effectiveness of the proposed indexes in the quantitative assessment of transient voltage stability for actual system. |
