Abstract: |
A method for compensating dynamic three-phase unbalanced loadsand and its device characterizing in sampling values of line voltage and load line current of two sample points at the connecting place of the compensation device and the system to compute related sine signal basic wave symmetric component, then to calculate positive and negative sequential compensator threephase equal susceptance, the sum of which is the three-phase susceptance value for compensating load unbalance and providing reactive current for the load, the susceptance reference value to be converted to a control angle signal and an order of the thyristor switched capacitor to be sent to the pulse generation plate and the condenser zero-cross trigger plate for controlling two devices. |
