| 摘要: |
| 智能电网使得保护利用远方信息不再困难,同时要求保护的定值能够自动跟踪网架的变化并保证故障切除后的系统坚强、自愈和高安全性。给出了主、后备保护的新型配置方案,后备保护利用相邻变电站状态信息,采用绝对选择性原理和多层次信息冗余,实现减少后备保护的数量并避免复杂的定值配合;以最后一次操作后系统不平衡能量最小为依据,减少操作对系统的冲击,给出了优化重合闸整定时间的理论和算法;以提高故障切除后系统的强壮性为目标,提出了同杆双回线的六相综合重合闸方案。 |

| Abstract: |
| It is no longer difficult to get remote information by relay protection in smart grid and it is also required that the settings of relay protection should follow the change of power network and the network should be strong,self-healing and high secure after fault is cleared. A new scheme of coordination between main and backup protections is presented. By applying the principle of absolute selectivity and multi-level information redundancy,the backup protection makes use of the state information from adjace... |
