摘要:
针对电网发生初始故障后的连锁跳闸现象，提出了一种提高电网安全水平的预防控制策略。结合继电保护的动作特性和连锁跳闸的特点，研究了电网在单一初始故障场景下和不同初始故障场景下的安全水平以及对应的预防控制模型，基于网络拓扑结构和电网运行状态分析得到筛选初始故障的综合指标。借助粒子群算法(particle swarm optimization，PSO)在IEEE14节点系统和IEEE39节点系统中进行仿真，结果表明：所提的预防控制模型能够有效地提高不同初始故障场景下电网的安全性。
Abstract:
Aiming at the interlocking tripping phenomenon after the initial fault of the power grid, a preventive control strategy to improve the security level of the power grid was proposed. Combined with the action characteristics of relay protection and the characteristics of interlocking tripping, the power grid security level of a single initial fault scenario and different initial fault scenarios, as well as their corresponding prevention and control models were discussed. Based on the two levels of network topology and power grid operation state, the comprehensive index for screening initial faults was obtained. Finally, particle swarm optimization (PSO) was used to simulate in the IEEE14 node system and the IEEE39 node system. Simulation results show that the proposed preventive control model can effectively improve the security of the power grid under different initial faults scenarios.
