风电机组变桨、偏航、主轴和发电机轴承等使用油脂润滑,目前采用集油瓶收集废旧油脂方法,轴承内旧油脂不能有效清理,变质硬化,轴承润滑失效.本文指出了现行的风电轴承废旧油脂清除方法及严重缺陷,重点对风电轴承废油脂自动清除及集中回收系统的详细介绍。风电轴承废油脂自动清除及集中回收系统结构组成: 液压泵、电磁换向阀、吸排脂器、废油回收器、监控器、传感器和管路附件等。 风电轴承废油脂自动清除及集中回收系统与集中润滑系统配套使用,在轴承充好油脂系统正常运行时,废油脂自动清除及集中回收系统从轴承中吸出的废油脂量接近集中润滑系统注入轴承的新油脂量。风电轴承废油脂自动清除及集中回收系统及时清理轴承内腔即将变质并带有磨屑的废旧油脂,减少轴承摩擦,利于轴承散热,大大降低轴承磨损,消除轴承内腔压力,保证内腔畅通,确保新油脂顺利注入轴承内腔,轴承油封也不再会被胀破,避免了油封漏油,也避免了污染物从油封胀破处侵入轴承内腔。和集中润滑系统配套使用,可使轴承内腔始终保持适量油脂,有利于润滑油膜的形成和保持,轴承寿命将得到大幅度提高,这时候才可以奢谈轴承20年的寿命。废旧油脂被集中压入废油回收器,既环保又清理便捷,利于回收利用。

本文介绍了一种简便的针对1.5MW 双馈风电机组的低压穿越改造方法,该方法不需要对机组的主控系统、变桨系统以及变频器进行任何改造,只要在机组并网点处串入一台低压穿越控制设备,就可使风电机组满足GB19963-2011要求的低压穿越能力.该低压穿越控制设备由主功率旁路和电压支撑回路组成,主功率旁路在正常工况下传输机组的发电功率,在电网故障工况下,主功率旁路快速关断,同时电压支撑回路在向电网端输出无功
