The document provides information about different groups in the power sector and their responsibilities. It discusses the current state of power generation, transmission, and distribution in India. Key challenges include high transmission and distribution losses, lack of proper asset management and monitoring systems, and political interference. The last section discusses automation systems that can help address some of these challenges.

- 4. Power Generation India has fifth largest power generation capacity in the world. Installed capacity of 162 GW (about 4% of global power generation). Per capita consumption 704 kWh (world average at 2300 kWh) 11 th plan target of 1000 kWh per capita consumption requires additional 100 GW power generation by 2012.
- 5. Power Transmission The current installed transmission facility is only 13% of total installed capacity. Ministry of power plans to establish integrated National Power Grid by 2012 with 200,000 MW power generation and 37,700 MW (additional 20,750 MW planned during 11 th plan) inter-regional power transfer capacity.
- 6. Power Distribution Transmission & Distribution losses stand at 33% substantially higher than global benchmarks. Reforms have been undertaken through unbundling State Electricity Boards into separate power generation, transmission & distribution units. Privatization of power distribution initiated through outright privatization or franchisee route.
- 7. Power Distribution continued While there has been slow and gradual improvement in metering, billing & collection efficiency, the current losses still pose a significant challenge for power distribution companies.
- 8. Generation History Full scale asset management & mapping Predictive, preventive and routine maintenance management Work order generation, activity scheduling. Open system platform and database management Enterprise-wise documentation management Manual logging of Data Huge Man power deployment. Vast count of instruments and data. Persons expertise required to run the machines.
- 9. Generation History Cont…. Manual follow up for running equipment in sequence. No automatic alarm generation in case of fault. No analysis provision available in the case of fault. Auto staring of stand by equipment in case of failure of one is not possible. Remote monitoring and control not available.
- 10. ABB Automation System in power Plant
- 11. Gross Generation 2004-05 Hydro 84497 GWh Nuclear 16638 GWh Thermal and Wind 486031 GWh No. Villages electrified 498286 Length of Transmission & Distristribution lines 6497727 Circuit km. Per Capita consumption 606.2 kWh Loss-- Transmission, Distribution, Transformation and Unaccounted energy 32.15%
- 16. Transmission History Analog meters need logging of data by persons. Controlling of over drawl by utilities is not possible. Lot of time is required to collect and summerise data for transmission lines running in 100’s of KM. No Grid discipline. Localised operation was possible. Quality parameters( Voltage, frequency andPF) monitoring was missing Non availability of monitoring system was one of the reason for not connecting different regional grids.
- 17. SCADA SUPERVISORY CONTROL AND DATA ACQUISITION Was introduced in 2002
- 18. As the name SCADA ( Supervisory Control and Data Acquisition) implies its functions are two fold: Scans the monitored system, obtaining and deriving data about the state and operating behavior of devices & Provides the capability to send control signal out to those devices to modify their operation
- 19. AVAILABILITY BASED TARIFF Intra-state ABT is a techno-economic tool for bringing rational tariff structure for supply of electricity from State generators to the distribution Licensees. It is a mechanism for enforcing discipline in the Grid.
- 20. Benefits of Intra – State ABT a) Benefits to the Power System Brings about grid discipline by maintaining frequency in prescribed band (49.5 to 50.5 Hz). Ensures optimum utilization of available generation capacities. Enhances opportunities for Open access, and Trading of electricity. Scope for encouraging competition among generators.
- 21. SCHEDULING Following processes of Scheduling has been automatized: Declared Capacity (Input) Entitlement Generation Discom’s requirement (Input) Open Access Transactions Inter Discom Transfer (Output) Drawl Schedule Generation Injections Schedule Generation Unrequisitioned surplus Generation Schedule generation on the basis of generation back-down. Printouts of the schedules on the intranet portal of SLDC. Automatic uploading of schedules on SLDC website on the lines of WRLDC. Automatic calculation of Inter-discom Transfer of surplus power.
- 22. Distribution History Power cuts Poor network. Long distribution lines. Outdated equipment. No Preventive maintenance No power in most of the villages even cities face the same problem. Low level of Generation Lack of Transmission network. Power to all by 2012. Loss level of Rs 26000 Crore. National Level of Loss 55%. High T&D Losses. No MIS Generation.
- 23. Distribution History Commercial losses. Theft of Electricity Non Payment of Bills Faulty meters No proper reading of meters Long processing time for Bills Manual bill preparation for energy consumed. No tracking of non payments. Loop poles in the billing system and high level of erroneous bills. Free power to vote banks. No asset management No balance sheets. IT implementation in piece meal basis. Core business operation having no IT implementation.
- 24. Parameters for Monitoring Revenue Enhancement Cost Reduction Shorten consumption to collection time Outage time / PLF Units Generated Quality Stable Voltage and Frequency. Enhanced customer Experience. Loss level monitoring( Energy Audit)
