INTRODUCTION
The solution chosen is based on ABB’s state-of-the-art
IED 670 for protection and
control of each bay and dual station HMIs in a hot-standby configuration. It also fea-
tures redundant
COM 581 communication gateways for telecontrol from the RCC at
Ballabhgarh and the RSCC at New Delhi. The system’s fault-tolerant ring configuration
using Ethernet switches with dual power supplies interconnects all IEDs including the
3rd party Main 2 protection IEDs, which have successfully been integrated.

messaging is used for software interlocks, auto-reclosing as well as triggering of distur-
bance recording. The complete substation, including the gas insulated switchgear and
transformers, is supplied by ABB as a
turnkey package. It is the first such station
to be equipped with Local Control Cubicles (LCC) that are locally engineered and man-
ufactured by ABB India.
