摘要
互联网运行方式类型持续增加,对于继电保护的要求也越来越高。为了使继电保护值校验和管理更加科学有效,提出一种基于广度优先搜索继电保护定值联系校核方法。在基于广度优先搜索,通过潮流转移度简化方法计算不同电力系统中不同支路的重要度。将风险评估理论和电网连锁故障风险相结合,获取系统综合风险,将其用于衡量不同保护的重要度;通过重要度从高到低的顺序对全部的保护值进行继电保护定值联系校核。仿真实验结果表明,所提方法能够有效提升继电保护定值联系校核效率,同时充分验证了所提方法的有效性以及优越性。
The types of Internet operation continue to increase, and the requirements for relay protection are also higher and higher. In order to make the verification and management of relay protection value more scientific and effective, this paper proposes a verification method of relay protection constant value contact from the perspective of breadth first search. From the perspective of breadth first search, the importance of different branches in different power systems is calculated by the simplified method of power flow transfer degree. Combining the risk assessment theory with the risk of power grid cascading fault, the comprehensive risk of the system is obtained, which is used to measure the importance of different protections. Through the order of importance from high to low, the relay protection settings are checked. The simulation results show that the proposed method can effectively improve the efficiency of setting contact checking, and fully verify the effectiveness and superiority of the proposed method.
