One of the biggest problem of the world is Power Shortage.
- Realization that electrical energy-sourced accessories to an evolving lifestyle are cleaner and thus more environmentally sustainable than other readily-available forms of energy provision.
- Not enough electrical generation to economically power all the consumption that has increased since that realization.
- Excessive space taken up by windmills, photo-electric arrays, generating stations.
- Excessive pollution caused by atomic and fossil-fueled electricity sources, CFL and CCFL lighting.
- Expensive electrical provision from general suppliers to consumer locations
- Lack of initiative to develop large coal and natural gas resources present in India
Current Scenario in India
- The electricity sector in India had an installed capacity of 223.625 GW as of April 2013, the world’s fifth largest.
- Captive power plants generate an additional 34.444 GW.
- Non Renewable Power Plants constitute 87.55% of the installed capacity and 12.45% of Renewable Capacity.
- Installed electricity capacity are shown in the below figure.
- Per capita average annual consumption in India – 96 kWh in rural areas & 288 kWh in urban areas
- Worldwide per capita annual average consumption – 2600 kWh
- India – world’s fourth largest energy consumer after United States, China and Russia.
Reason of Increasing Demand
- India’s manufacturing sector is likely to grow faster than in the past.
- Domestic demand will increase more rapidly as the quality of life for more Indians improve.
- About 125,000 villages are likely to get connected to India’s electricity grid.
- Currently blackouts and load shedding artificially suppresses demand.
- Increasing Population.
- Awareness Program.
- Increase Power Generation.
- Use Efficient Equipment.
It has been broadly classified into four categories: IT Sector, Heating Ventilation Air Conditioning (HVAC), Lighting and Electric Motor.
Commonly used motor are: DC Motor (DCM), Synchronous Motor (SM) and Induction Motor (IM). Out of which induction motor is mostly used motor which have 50-60 % efficiency. If we can have efficient motor than power shortage can be reduced.
The solution is Permanent Magnet Motor which is of two types: PMSM (Permanent Magnet Synchronous Motor) and PMBLDCM (Permanent Magnet Brushless Direct Current Motor). Both the motors have 80-90 % efficiency. PMSM is available with High and medium power rating i.e. used in satellite etc. PMBLDCM is available with lower power rating i.e. used in computer etc.
