| 摘要: |
| 开展大规模风电场并网送出电网继电保护实时数字仿真（RTDS）试验，指出现有风电场送出电网继电保护存在的问题，给出风电场送出电网保护配置建议：110 kV送出线路的主保护采用分相电流差动保护，后备保护采用解微分方程算法的距离Ⅰ段，或将相量距离Ⅰ段保护延时0.15 s动作，同时配置常规距离II、III段及零序电流保护；送出变压器主保护采用差动保护，励磁涌流判据采用间断角鉴别、时差法等方法，后备保护配置复合过电流保护及零序电流方向保护；330 kV送出线路主保护配置2套独立工作的分相电流差动保护，采用电压突变量选相元件及基于零序分量的方向元件，后备保护配置与110 kV送出线路相同。（详见2013年第33卷第7期） |

| Abstract: |
| The RTDS experiment is carried out for the relay protections of outgoing power grid of large-scale grid-connected wind farm and its existing problems are pointed out. The corresponding suggestions about the relay configuration are proposed：the main protection of 110kV outgoing transmission line should adopt the phase-split current differential protection while its backup protection adopt the distance section I using differential equation algorithm，or the time setting of phasor-based distance section I be prolonged by 0.15s while the conventional distance section Ⅱ，distance section III and zero-sequence current protection be equipped；the main protection of outgoing transformer should adopt the differential protection with the inrush current criterion using the dead angle identification，time-difference method，etc. while its backup protection adopt the compound over-current protection and zero-sequence current direction protection；the main protection of 330 kV outgoing transmission line should adopt two independent sets of phase-split current differential protection with the voltage sudden-change phase selector and zero-sequence directional component while its backup protection adopt the same configuration as that of 110 kV outgoing transmission line. |
