Source 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 the
CT location
power access point of the module.
User can choose source or load side to install CT.
Disable: When the overheat protection sensors of the module detect
the temperature of IGBTs more than 95℃, the output won't be
derated.
Enable: The module derating capacity is judged by detecting the
Temperature
IGBT temperature. When the temperature exceeds 95℃ and the
derating
duration reaches ten minutes, the module will automatically derating
10% of rated capacity. If the temperature still exceeds 95℃ and the
duration reaches ten minutes, the module will automatically derated
10% capacity based on the capacity of last derated. By analogy, the
maximum derating capacity of the module is 50%, but when the
temperature is less than 85℃, the module will automatically back to
the original rated capacity.
Take SVG 100K as example, when the temperature of the IGBT
reach 95℃ and lasts 10 minutes, it will reduce 10% capacity, then
the SVG capacity is 90K. SVG will detect the temperature again, if
the temperature is still rising and lasts time is 10 minutes, it will
reduce 10% capacity again, then the SVG capacity is 80K. If
temperature reduce to 85℃ after derating, the SVG capacity will
return to 100K.
This function could make SVG generate constant reactive power to
the grid. No need of CT, because it's output reactive power is

RP Tracking Ctrl Val means "Reactive Power Tracking Control
Value".
This parameter can be set to output either a constant inductive or
capacitive reactive power into the system, before the system will
perform its normal reactive power compensation function, as
