WVP variable load motor reactive power compensation device

Model: WVP variable load motor reactive power compensation device

1)range of application
applicable for 75kw--10000kw wound rotor asynchronous motor
reactive power local compensation and power save.
especially for motors always working in changing-load condition, such as loaded with fan, pumps, mill ball, etc.

2) Unique feature:
1:WVP is national patented,:accurate compensation according to actual motor loading.

2:high efficiency
increase motor power factor to over 0.95---0.99;
reduce reactive power more than 60%
reduce motor stator current 10-20%;
save line loss and copper loss 20-30%

3:Adopt double CPU control and adjusting the related parameters according to changing load , realize dynamic compensation and make power factor in optimal state all the time

4:decrease the stator current and winding temperature rising, improving power factor and efficiency, to reduce the loss of the motor and power system.

3)characteristic
1:independent working system from motor, can adjust and maintenance without stop the motor. Automatic tracking rotor current ,for constant torque load and changing torque load

2:with function of malfucntion record, over current, low voltage, less phase, outer fault, communication failure, parameter mistake protetion
3:man-machine interface, LCD screen interface , simple operation, with reliable and all-round automatic fault protection function without influence on production in paintenance and take-care .
4:can take back the cost within half a year

4) Working principle:
standard of conformity: GB3797; Q/XWZ11-2066

when motor work in load , rotor current is l2e, stator current is l1e, drawing as above
U: voltage vector; l1 stator current vector ; l2 rotor current vector; lm exciting current vector;
l1e stator current rated vector; l2e rotor current rated vector; Φ1 motor rated power angle factor
Φ2 after compensation power angle factor
5:environment temperatue: -40C---+50C
relative humidity of air no exceed 90%
