摘　　要：针对风电场接入系统联络线与风电场变压器的继电保护配置与整定,分析了风力发电机有无低电压穿越(LVRT)功能对保护配置与整定的影响,并利用M ATLAB/S im u link软件仿真了具有LVRT功能风力发电机组的短路电流。仿真结果表明,低电压穿越有助于提高快速保护的灵敏度,但也增加了后备保护配置的复杂度,因此,合理的保护配置与整定值有利于保证系统的安全。In this paper, the authors analyzed the protection＇s configuration and settings of interconnection line and transformers in wind farm. On base of this, it discussed the influence of wind power generator with LVRT （low voltage ride through） or not. It also constructed simulation module of generator with LVRT to obtain short-circuit current by MATLAB/Simulink. As a result, it would increase sensitivity of main relays, however it increased complexity of backup protections, to assure grid＇s security, it must adopt appropriate protection＇s configuration and settings.
