Interconnection to EEA substation and Zafarana
Electric System TB2
LOCATION Cairo Airport
CLIENT Cairo Airport Company
FIRM’S RESPONSIBILITIES Design & Supervision of Installation
The objective of this renovation is to replace all the existing electrical system without the interrupting the working conditions of TB-2.
The new electrical systems is designed to use all advantages of existing system and avoid any disadvantages.
New system and equipment were introduced to the electrical system, e.g. dry type cast resin transformers, SF6 medium voltage switchgear with new technologies, the latest moderate power monitoring and control system, P.F. correcting capacitors, voltage regulators, …. Etc.
Also a detailed load analyses together with simultaneous field measurements of load variations and characteristics at various location carried out. A harmonic analyzer was used in pre-selected location of the M.V./ L.V. network to monitor and record variations in the current, voltage, p.f., harmonic content,… etc. of the supply.
Automatic voltage regulators (A.V.R) which acts and responds automatically to correct the voltage to the nominal voltage 11 K.V was used.
By- pass switches shunting the isolating transformer (T4), to keep the reliability of the supply to the essential loads.
The ratings of some distribution transformers in the system was increased to allow increasing the essential loads, supplied by the emergency diesel- generator sets in case of power failure and allow for future expansion.
The SCADA ( Supervisory, Control and data acquisition ) system was incorporated in the new system to enable remote monitoring and control of all M.V. circuit breakers and main L.V. circuit breakers, also the system employ the most update tele-metering technology and software packages.
Essential lighting for “arrival” and “departure” and other halls shall be increased from 25% to 100% of the total lighting load belt conveyors emergency loads will be increased to 100% . For 400 cycle station ,emergency loads will be increased to 50% .
The control panels and The synchronizing panel of the existing diesel generators sets were changed to new digitally control panels and employs modern power electronics technology.
For air- conditioning, it was arranged for the provision of an additional transformer rated at 2.5 M.V.A & 11KV and 6.6KV panels for the planned third chiller. Also the existing 6.6KV panels feeding the chillers were replaced with new up-graded panels.
