Evaluation of the scada system in GTCL

Abstract

Gas TraIlllITllssion Company limited (GTCL) was incorporated in 1993 in the unbundling process of gas sector restructuring for owning, operating and maintaining the high pressure gas transmission pipelines forming a part of the natiolUl! gas grid. Around 70% of total produced gas is transmitted by GTeL pipelines. In order to ensure smooth and efficient pipeline operation, it was dedded to incmporate a Supervisory Control And Data Acquisition (SCADA) system by GTCL. It was dnly installed and commissioned in 2004. The main objective of this study is to frod out the reai impacts of the SCADA system. This is done by carefully studying and itemizing the tangible and intangible benefits directly arising out of the SCADA system. Shortcomings are also identified which need to be removed in order to get maximum benefits from the SCADA system. Financial analysis is performed from two perspectives such as-gas sector perspective and national perspective to justify the implementation of the system. The froancial parameters of gas sec10r perspective reveal that the project is not financially viable while it is viable for national perspec1ive.
