EES covers the design, supply, engineering; testing and commissioning of PLC based capacitor control system.
For Saudi Electricity Company There are different combinations are required in different substations as follows:
1 capacitor bank connected to the 13.8 kV bus.
2 capacitor banks connected to the 13.8 kV bus
3 capacitor banks connected to the 13.8 kV bus.
1 capacitor bank connected to the 33 kV bus.
3 capacitor banks connected to the 33 kV bus.
Each capacitor bank shall be brought on-line/off-line with the 13.8kV/33kV bus in
case of an increased/decreased demand of reactive power on the bus, The reactive power reference values are stored in the PLC.
System and HW adopted for these schemes :
- Lumel Power Meters.
- PLC Systems : Possibility to use Allen Bradley, Siemens, GE-IP and Schneider PLCs.
- ISKRA Transducers.
- EES Announciation System.
