Advanced Distribution Management System: An Integrated System

Abstract

Tata Power-DDL has been the frontrunner in implementing power distribution reforms in the capital city and is acknowledged for its consumer friendly practices. The company has implemented high-tech automated systems for its entire distribution network. In the world of digitalization, TATA POWER-DDL adopted smart technologies like SCADA-DMS and OMS to improve reliability and customer outages. These were implemented at different times, from different vendors and operated in different environments resulting in inefficient outage durations, non-optimal costs, and customer dissatisfaction. The flow of information from DMS to OMS happens through ICCP, but no reverse flow of information from OMS to DMS happens. Consequently, the DMS dispatchers have no clue as to the impact of outages on customers and OMS dispatchers have little clue about the cause of outages. This often results in delayed and to some extent, inaccurate information being conveyed to the customers, and no benefit accruing to reliability from customer calls. For better efficiency, digitalization of network and outage management, accurate reporting integration of the two systems was required. However, technological integration was beyond question due to the incompatibilities in technologies, vendors and data systems. So Advance Distribution Management System (ADMS) has been implemented to manage all levels of outages efficiently. This system acts as an integrator between all IT & OT systems, which is integrated with SAP-CRM, GIS, MWM/FFA,ICCP, Power manager portfolio, SAP BW-BO, RTU/DCU/FRTU/IED, Social media etc. In the near future we are going to integrate it with EV charging Solar Roof top, Battery storage, micro grids, Energy Audit, DPS (CYME, ETAP), HES, MDMS, ADR etc. Thus, ADMS is going to be the biggest integrator in the utility sector which will lead us towards the digitalization of our utility. This will also lead to desired improvements in reliability and customer outage services. This paper attempts to outline and analyze the issues in the old system and explain how the new system has addressed those issues and added value to the utility by improving reliability and customer services simultaneously.
