摘要

从对电网的影响来看，环变流器同步电机系统的磁场定向控制是工业上应用最严重的问题之一，特别是在负荷变化较大的矿山和钢厂。提出了一种基于驱动系统本身的动态无功补偿方法。与传统的无功补偿方法相比，该方法补偿性能更好，成本更低。已经详细描述了补偿的哲学。此外，还给出了一种矿井提升机驱动系统动态无功补偿的具体控制方案。仿真结果验证了该方法的有效性。

New method of reactive power compensation of field-oriented control of cycloconverter-fed synchronous motor driving mine moist

From the point of view of influence on supply net, the field-oriented control of cycloconverter-fed synchronous motor system is one of the severest applications in industry, especially in mine plant and steel plant which have very large load variations. A new method of dynamic reactive power compensation based on the drive system itself is illustrated in this paper. Compared with conventional reactive power compensation methods, this method of compensation performs better and costs less. The philosophy of compensation has been described in detail. Moreover, a specific control scheme of dynamic reactive power compensation is given to one of the mine hoist drive systems. The simulation results verify the validity of this new method.
