摘要
根据故障切除后负荷转移的情况进行事故预想,防止接连事故的发生,是确保电力系统安全稳定的重要措施。为此,提出了线路相关集的概念和基于最短路径算法的线路相关集搜索方法,给出了线路相关因子的求解办法。在此基础上对预想事故后的潮流转移进行快速计算,准确地判断出过负荷线路。用CEPRI36节点系统进行了仿真验证,证明了所提方法的正确性和有效性。
In this paper, a new concept RCTL（relative cluster of the transmission line） and the corresponding searching algorithm are proposed, and the method to calculate relative factor of RCTL is introduced. On this basis, the power flow transferring after contingency could be calculated and the overloading transmission line could be determined rapidly and correctly. Taking CEPRI 36 - bus system as the case, the power flow transferring is simulated and the simulation results show that the algorithm is accurate and effective.
