week10 day 3: IFAS

salam~

today, mr maswan explain about the IFAS system or Intelligent fire alarm system in the complex.

then at 11am we went to GDC, gas district cooling for a visit.

Gas District Cooling (GDC) Co-generation Plant

The GDC plant is equipped initially with 2 x 20MW gas turbine generators. The output of the generators at 11 kV is stepped up to 33kV by individual 11/33kV, 27 MVA transformers and fed to a 33kV switchboard. From this 33kV board, supply to the KLIA EPS at SSA Substation is provided via 2 x 33kV cable feeders (each rated for 40MVA), 200m in length.The neutral of the 33kV winding for each transformer is earthed via a common 1600A Neutral Earthing Resistor. 
The auxiliary consumption of the Cogen Plant is about 8MW, which leaves approximately 32MW available for export to KLIA EPS via the two aforementioned 33kV, 40MVA underground cables. The capacity of each cable, at 0.85PF (Power Factor) is 36MW. These cables are installed and maintained by GDC.
