TECHNOLOGY DEVELOPMENT
Adopting New Technologies In Transmission System
New technologies would need to be adopted and implemented in a proactive
manner to achieve the objective of optimum utilization of the available
transmission assets as well as conservation of Right-of-Way, reducing
transmission costs, reduction of losses etc. Some of the new technologies
adopted/being adopted in its transmission system include:
High capacity 6000MW +800kV HVDC system
765kV AC Transmission System
Ultra High Voltage AC Transmission System(1000kV)
Application of Series Compensation
Flexible AC Transmission System (FACTS)
Upgradation/Uprating of transmission line
High temperature endurance conductor
Tall/Multi-circuit & Compact tower
High Surge Impedance Loading Line (HSIL)
Remote operation of substation, substation automation and Gas Insulated
substation (GIS)
All Aluminum Alloy Conductors (AAAC) and Polymer/Composite
Insulators.
Development of disc insulators of 320kN & 420kN indigenously for both
AC & HVDC applications, as import substitution.
Indigenous development of semi-conducting glazed insulators (Offering
better pollution performance)
Introduced source/process inspection of equipment to ensure zero defect
Airborne Laser Terrain Mapping (ALTM) for detailed route survey
Thermo-vision scanning of the lines and sub-stations
Conditional monitoring of equipment
Preventive maintenance of Transformers using State-of-art Oil testing
laboratories set up by the company
Emergency Restoration System (ERS)
For modernization of transmission system through latest technology integration,
two pronged strategies have been envisaged as under:
Enhance capacity and reliability of existing systems.
Suitable technology for new systems keeping in view the long term
perspective
Planning suggestions by CEA
