Page 72
Some grid connection rules insist that the agreed reactive power be supplied from every operating point of the plant without a reduction in the actual active power. Considering the fact that all KACO TL3 inverters have a semi-circular P-Q operating range, a reduction in the active power is, however, required during operation at maximum active power be- cause an apparent power reserve is not available.
Enhanced island detection method The enhanced island detection of KACO new energy, employs a strategy to reliably detect island formation that is based on the characteristic differences between an interconnected grid and an islanded grid, thus ensuring reliable fast detec- tion and prevention of false tripping.
