地区电网可靠性评估方法研究

摘要

The research on the reliability assessment of regional power grid,which connects to power consumers,becomes an important issue. A simplified equivalent method is adopted to simplify regional power grids in network composed of branches and nodes. The modified minimum path algorithm is implemented to assess and calculate the reliability of regional power grid. Taking the calculation and analysis of a regional power sgrid as an example,the method is verified to be effective in reliability assessment of regional power grid.%　　地区电网是直接与电力用户连接的一级电网，研究和评估地区电网的供电可靠性已成为一项重要的课题。为了实现评估地区电网可靠性的目的，采用简化等值的思路将地区电网简化等效为支路和结点组成的网络，并以修正的最小路算法对地区电网的可靠性指标进行评估计算。通过对某地区电网为例进行计算分析，验证了该方法能够有效地对地区电网进行可靠性评估。
