Grid support

Grid support means that capacitive reactive power is fed to the grid during a voltage dip. Grid support
settings can be set in parameter group
The reactive current reference is defined as a function of the grid voltage. Four different voltage
levels can be defined. When grid voltage is between the defined levels, linear extrapolation is used to
calculate the exact reactive current reference. The grid support function is activated and the
operation mode selected by parameter
defined by parameters 41.03...41.10. A fixed amount of reactive current can be given with parameter
41.11 RT IQREF. If the value of parameter
41.03...41.10 are bypassed. The reactive current ramp-up time at the beginning of LVRT can be
changed with parameter
Grid support is not active in the extended dip range defined in group
Settings
Parameters are visible but password-protected. The PVS800 has to be stopped when parameters
are changed. LVRT must be active. Parameter
For further information on grid support, see parameters 40.01...40.12.
