Sinexcel SVG 100 Ultra User Manual page 56

Parameter
There are 6 working modes applicable to SVG
Reactive: Reactive power compensation
Q: Reactive power compensation
B: Three phase unbalance compensation
Auto-aging: The module outputs current according to set
compensation rate, which tests whether the module can output
normally.
Operation
(Only factory of Sinexcel testing. User shall be forbidden to use.)
Mode
Mixed mode: Used for mixed solution, AHF+SVG
(Refer to document <One Centralized HMI to Control SVG&SVG
Hybrid System> attached for further explanation.)
For example: Q+B means reactive power compensation first, then
compensate three-phase unbalance compensation.
Manual: It needs to be started by artificial execution in the
monitoring interface.
Power on
mode
Auto: In automatic mode, once the system is connected to power,
machine will automatically on and start working.
Supply side: CT installation position is closer to the grid
transformer side than the power access point of the module.
Load side: CT installation position is closer to the load side than
CT location the power access point of the module.
Note: If there is LC or capacitor bank in the system,
please consult the engineer of Sinexcel and provide
single line diagram.
Total Total Capacity setting is the total capacity of the system, either
Capacity single module or combination of multiple modules.
The unit is A that for SVG system, need to transfer the kVAr as A;
The formula is P=Root3*U*I
Intelligent compensation: Using intelligent Fourier algorithm, the
rated capacity can be compensated within five minutes, effectively
avoiding resonance.
Comp.
Sequential compensation: Using Fourier algorithm, can quickly
Mode
compensate the harmonics of the order to rated capacity.
All compensation: Quickly compensate all harmonic!!!s. (not
recommended)
The parameter is useless in SVG system;
The setting value need to correspond to the actual ratio of external
CT. The secondary of CT only can be 5, the setting range:
CT ratio
50~30000.
Note: ① 500 means 500:5. ② If the CT ratio is
1000:1, then it should be set as "5000".
