Product Description

■　Product profile

■　Model description

■　Configuration & working principle

The three-phase unbalanced intelligent regulating device can analyze the three-phase load imbalance situation according to the AC sampling of the sampling circuit when power on,calculate the current value and phase to be compensated,send the signal to IGBT by the signal generator,and send a current signal to the system by the inverter to meet the requirements,so as to realize the three-phase load balance regulation.

The device can realize inductive and capacitive bidirectional dynamic reactive power tracking compensation by adjusting the remaining capacity of the device after three-phase imbalance,detect the load current in real time,analyze the reactive power capacity of the load current by DSP calculation,control the signal generator according to the set compensation range,output the signal to IGBT drive circuit,and make the inverter to generate reactive current which is equal to the reactive component and in opposite direction of the system,so as to achieve the purpose of real-time dynamic tracking compensation reactive power.
