Energy Requirement & Installed Capacity of SGS & Share from Central sector

•Endpoint To Endpoint Long Haul Bulk Power Transmission Without Intermediate Tap.•Reducing Line Cost. Since HVDC Transmission Requires Fewer Conductor.•Increased Stability of Power System•Reducing Losses(Corona loss, Skin effect)•Lower Investment Cost because NO REACTIVE LOSS.• Increasing the capacity of an existing power grid in situations where additional wires are difficult or expensive to install.

Why choose HVDC

WHAT IS SMART MATERIALS

SMART MATERIALS

Smart material are those materials that posses the ability to change their physical properties in a specific manner in response to specific stimulus input.Stimuli could be pressure, temperature, electric & magnetic field, chemicals, nuclear radiation etc.The associated changeable physical property could be shape, stiffness, viscosity, damping etc.

PROPERTIES OF SMART MATERIALS

• Sensing materials and devices• Actuation materials and devices• Control devices and techniques• Self-detection, self-diagnostic• Self-corrective, self-controlled, self-healing• Shock-absorbers, damage arrest

TYPE & EXAMPLE OF SMART . MATERIAL

Piezo-electric polymer and ceramic(silk, DNA, ZnO etc)

Electro-rheological(ER) fluid(mixing cornflour in a light vegetable oil or (better) silicone oil etc.)

Magneto-strictive materials(cobalt ,terfenol D etc) Shape memory alloy (SMAs) (copper-aluminium-

nickel & nickel-titanium (NiTi) alloy etc) Fiber optics.

PICTURES OF SMART MATERIALS

Nitinol alloy Piezoelectric film, PVDF

Terfenol Material Piezoceramic, PZT

High energy density.Excellent bandwidth.Smart materials have better durability and reliability.Smart materials reduces the production cost.Smart materials reduces the weight of component used in the mechanical & electrical industries.Smart materials are gives excellent results in Electrical Technology & Communication Technology.Smart materials get smarter with ability to better control of shape & size.

ADVANTAGES OF SMART MATERIALS

LIMITATIONS OF SMART MATERIALS

Smart materials are very expensive. They are not easily available in market. They are very sensible so they need proper care

while storage it. Smart materials needs proper skill to recognize it

among other materials.

Conclusion

Today, the most promising technologies for lifetime efficiency and improved reliability include the use of smart materials and structures. Understanding and controlling the composition and microstructure of any new materials are the ultimate objectives of research in this field, and is crucial to the production of good smart materials.

New and advanced materials will definitively enhance our quality of our life.
