日期：2021-5-8一、再生制动的应用
一条化纤长丝牵伸生产线，由三台牵伸机组成，分别由三台电机驱动。一辊电机功率22KW、4极，采用蜗杆减速器，速比为25：1；二辊电机功率37KW、4极，蜗杆减速器，速比16：1；三辊电机功率45KW，采用圆柱齿轮减速器，速比6：1。电机分别采用华为TD2000-22KW三垦IHF37K，45K变频器驱动。三台变频器根据牵伸比及速比采用比例控制。它的工作过程是这样的：丝束绕在一辊、二辊、三辊上，由变频器控制三辊之间不同的速度对丝束进行牵伸。
开车调试时因牵伸比小，丝束总旦较低，系统开车正常。在投产一段时间后，由于工艺调整，增大了牵伸比及丝束总旦，（牵伸比由工艺决定，总旦通俗的说，就是丝束的粗细及根数多少，总旦越高，丝束越粗。牵伸倍数或总旦越大，三辊对二辊、一辊的拖力越大。）这时出现了问题。开车时间不长，一辊变频器频繁显示SC（过电压防止），
二辊变频器偶尔也有这种现象。时间稍长，一辊变频器保护停机，故障显示E006（过电压）。通过对故障现象进行仔细的分析，得出以下结论：由于一辊与二辊之间的牵伸比占总牵伸倍数的70%，而二辊、三辊电机功率均大于一辊，因此一辊电机实际工作于发电状态，它必须产生足够的制动力矩，才能保证牵伸倍数。二辊则根据工艺状况工作于电动与制动状态之间，只有三辊为电动状态。
也就是说，一辊变频器若不能将电机产生的再生能量处理掉，它就不能产生足够的制动力矩，那么将会被二辊“拖跑”。被“拖跑”的主要原因在于变频器为防止过电压跳闸而采取的自动提高输出频率的功能（即“SC”失速防止功能）。
变频器为了降低再生能量，将会自动增加电机转速，试图降低再生电压，但是因再生能量过高，所以并不能阻止过电压的发生。因此，问题的焦点是必须保证一辊、二辊电机具有足够的制动力矩。增加一辊、二辊电机及变频器容量可以达到这个目的，但这显然是不经济的。而将一辊、二辊产生的过电压及时处理掉，不让变频器的直流电压升高，也能够提供足够的制动力矩。
由于在系统设计时未考虑到这点，采用共用直流母线吸收型或能量回馈型的方法已不可能。经仔细论证，只有采用将一辊、二辊变频器各增加一组外接制动单元的方案。经计算选用了两组华为TDB-4C01-0300制动组件。开车后两组制动单元电阻尤其是一辊制动阻工作频率非常之高，说明我们的分析是正确的。整个系统运行近一年，再也没有发生过过电压现象。 咨询热线：18150708278
