Challenges in Transmission and Distribution

Challenges in Transmission & Distribution

Capacity building, network planning and operational efficiency

Ageing infrastructure

Regulatory mandates

AT&C loss reduction, Energy accounting & Auditing

Business process efficiency, Reducing manual processes

Increasing pressure on service reliability (e.g. CAIDI, CAIFI)

Metering, Billing and Collection efficiency

Significant change in network dynamics with distributed energy resources

Plant Automation – Each of the generating stations have its own DCS

Transmission – Unified SCADA System, Nodal SCADA System

Distribution - Distribution Automation System, Metering, AMR enabled meter

Enterprise Resource Planning (ERP) system SAP to manage various business processes (e.g. HR, Finance &, Accounts, Procurement etc).

Oracle Hyperion for managing Balanced Score Card

Load Control Centre Automation

Load Control Centre - Tata Power

Load Control Centre - Functions

Nerve center for operation, Control, Monitoring and Planning of power systemLoad forecasting, generation and outage planning of hydro and thermal stations, power purchase from other constituentsPreparation of long-range and medium-range operation plan including outage coordination for own system and in consultation with the load control center of the neighbouring system.Preparation of daily and hourly operating plansEnsures uninterrupted power supply to consumer by real time load generation balance, network availability, planning equipment outages considering contingencies.Monitors system security in terms of outages, generation, reserves and loading on transmission lines / transformersInitiates and monitors emergency measures like low frequency operation, load shedding and system separation etc in line with accepted policies.Energy balance and auditing of energy injection into the grid and sale to consumers.

EMS Applications – Load Control Center

Optimized monitoring, control and asset management of large electrical network is achieved using real-time data and following EMS applications:
