并网型风电机组正常运行需保持与电网连接,当电网故障引起风电机组系统掉电或电网恢复后,风电机组系统再次上电时,风电机组系统会产生大量派生故障,掩盖真实的故障记录,不利于对机组运行状态分析判断.本文针对上述问题对风电机组系统时序进行试验分析,研究其对风电机组故障记录的影响.结果表明:合理的风电机组系统时序能有效地消除派生故障,达到还原真实故障记录的目的.

@@@@Grid-connected wind turbine needs to connect to grid for normal operation. When the wind turbine system is powered o caused by the grid fault or a er the recovery of grid while the wind turbine system is power on again. Wind turbine system will produce a large number of derived faults and the real faults are covered. It is di cult to analyze and judge on the operation state of wind turbine. For the above questions, this article takes tests on the sequence of wind turbine system to analyze the in uence of the fault record of wind turbine system. e results show that reasonable sequence of wind turbine system can e ectively eliminate the derived fault, in purpose of restoring the real fault record.
