中文摘要：

采用中国电科院开发的PSD-BPA潮流稳定程序，运用“N-1”原则，研究了接入特高压输电系统对安徽电网静态电压稳定性及暂态电压稳定性的影响，并分析了特高压系统对安徽电网无功补偿的影响。通过仿真计算，揭示了安徽电网在接入特高压后的潮流分布、静态和暂态电压稳定性特点，以及无功补偿问题。

英文摘要：

PSD-BPA flow stability program （ developed by Electric Power Research Institute of China） and ＇ N - 1＇ method are adopted to analyze the influence of UHV transmission system on the static and transient voltage stability and reactive power compensation of Anhui power grid. The simulation results illustrate the characteristics of UHV-integrated Anhui power grid in terms of power flow distribution, static and transient voltage stability, as well as reactive power compensation.
