摘要 继电保护一体化图形拼接后电网规模不断扩大,运行方式越发复杂,继电保护整定计算不可避免地存在计算维数过高,计算量过大且求解效率过低等问题。深入研究一体化继电保护图形拼接的特点,提出了一种基于Mean Shift算法和层次聚类算法的MSHC继电保护一体化图形智能分区方法。根据割集最小、互感支路处于同一个子区域、子区域内厂站个数适中的三个厂站划分准则确定最优厂站分区方法。最后通过实际电网算例验证了该方法的快速性及有效性。 The protective relaying setting calculation has encountered several obstacles, such as high calculation complexity, excessive calculation procedures and low efficiency due to the growing range of network scale and the increasingly complex operation mode when splicing graphics of different areas. This paper makes an intensive research on the integrated protective relaying graphic mosaic, and promotes a Mean Shift algorithm and hierarchical clustering algorithm based MSHC intelligent partition method for integrated protective relaying graphic. The optimal station partition could be accomplished following these three principles: the cut set is the smallest; the branch with mutual inductance is within the same sub-area and the quantity of the station within the sub-area is appropriate. Finally, the effectiveness and rapidity of this method is verified through an actual network.
