Title
(EN) Transmission line switching combination scheme establishment method and device
(ZH) 输电线路投切组合方案建立方法及装置
Abstract
(EN)
The invention provides a transmission line switching combination scheme establishment method and device. The method is applied to the technical field of power systems, and comprises steps: an initialcut-off line number k and the maximum cut-off line number kmax are set; k-self impedance of each to-be-detected node after the k lines are cut off is calculated; according to k-self impedance of eachto-be-detected node, a k-line qualified scheme and a k-line unqualified scheme are determined; the initial cut-off line number k is added to k+d according to a preset step d; if k+d kmax or the current to-be-detected node set is empty, current line switching combination scheme establishment is determined to be completed. The transmission line switching combination scheme establishment method and the device provided by the invention can quickly establish a switching combination scheme.

本发明提供了一种输电线路投切组合方案建立方法及装置,该方法应用于电力系统技术领域,所述方法包括:设置初始切除线路数k和最大切除线路数kmax;计算每个待检节点在切除k条线路后的k‑自阻抗;根据各个待检节点的k‑自阻抗确定k线合格方案和k线不合格方案;根据预设步长d增加所述初始切除路数k至k+d;若k+d≤kmax,则将k线不合格方案中的节点作为待检节点,并返回执行计算每个待检节点在切除k条线路后的k‑自阻抗的步骤;若k+d>kmax或当前待检节点集为空,则确定当前线路投切组合方案建立完成。本发明提供的输电线路投切组合方案建立方法及装置能够快速建立投切组合方案。
