System side voltage UA = 100V, phase 0 degree, frequency 50Hz. System side
parameter is constant value. Set the shunt side voltage UB = 90V, 0 ° phase, frequency 50Hz.
It can be seen that only amplitude is not a constant, the other two meet the conditions ,
manually or automatically increments UB, when it closes to UA phase amplitude ,
synchronization device acts, the program records the UB amplitude to be the action voltage
value.
3.2 Test operation frequency
System side voltage UA = 100V, phase 0 degree, frequency 50Hz. System side
parameter is constant value. Set the shunt side voltage UB = 100V, 0 ° phase, frequency
49Hz. It can be seen that only frequency is not a constant, the other two meet the conditions ,
manually or automatically increments UB, when it closes to UA phase frequency ,
synchronization device acts, the program records the UB frequency to be the action
frequency value.
3.3 Test action phase
System side voltage UA = 100V, phase 0 degree, frequency 50Hz. System side
parameter is constant value. Set the shunt side voltage UB = 100V, 340° phase, frequency
50Hz. It can be seen that only phase is not a constant, the other two meet the conditions ,
manually or automatically increments UB, when it
closes to UA phase value , synchronization device acts,
the program records the UB frequency to be the action
phase value.
3.4 Automatic synchronizing adjustment
As shown in the following picture, both sides only
phase equal to each other, the other conditions are not
satisfied the synchronizing conditions , the difference
is that the variation frequency and the variation
amplitude of the command is not controlled by the
program , but by the output value of the
