| 摘 要： | 电力系统的静态电压稳定裕度是评估系统静态稳定的重要指标，它是计算电压稳定限制的区域电力系统间输电能力的重要依据，也是系统选择是否进行预防控制措施的重要参考点。贵州电网“十三五”规划及相关专题要求对贵州电网“十三五”期间静态电压稳定裕度进行计算分析，而现有的静态电压稳定裕度分析软件如VSAP等存在计算节点数量限制，难以满足“十三五”期间贵州电网的静态电压稳定裕度计算要求，因此有必要寻求一种新的途径来求取贵州电网静态稳定裕度。文章提出了一种采用BPA潮流计算程序与MATLAB程序相结合的计算方法，BPA潮流计算程序主要用于系统的等值简化，MATLAB程序主要用于静态电压稳定裕度的计算，求解的算法采用最优潮流法。用此方法计算贵州电网“十三五”期间的静态电压稳定裕度，计算结果表明该方法有效可行，可推广应用于其他省级电网及区域电网的静态电压稳定裕度计算分析工作中。

| Abstract: | The static voltage stability margin is an important index to assess the static stability of power systems. It′s not only the significant basis of computing transmission capacities between regional power systems under the limit of voltage stability, but also the significant reference point for power systems to decide whether to adopt preventative measures. The 13th five-year plan of Guizhou power grid and relevant researches demand to compute the static voltage stability margins of Guizhou power gird during the 13th five year plan period. But current static voltage stability margin analyzing tools such as VSAP have certain limits in capable computing node numbers, which can′t satisfy the demand of computing the static voltage margins of Guizhou power grid .Thus , it′s necessary to find a new path to obtain the static voltage stability margins of Guizhou power grid. This paper puts forward a computing method using both PSD-BPA and MATLAB. PSD-BPA is mainly for system equivalent reduction, while MATLAB program is optimal power flow method responsible for computing the static voltage stability margins. The computing results demonstrate the feasibility and effectiveness of the method which can be further applied in the static voltage stability margins computing work in other provincial level power girds and regional power grids. |
