Abstract :
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
