PREPAID SMART CARD OPERATED ELECTRONICS ENERGY METER WITH ONLINE LOAD OPTIMIZER FOR SOLAR POWER APPLICATION.
Abroad: South Africa
No: 2009/03660; Grant date 31-MAR-10
The smart card operated prepaid energy meter uses embedded technology to dispatch electricity at the consumers end. It displays the consumption of
electricity (KWH) along with balance amount (Rs) through a front end display fitted into the meter. It facilitate improved cash flow management in energy utilities and can reduces problem associated with billing for consumer particularly living in isolated rural area where electricity is generated and
distributed solar mini grid.
The meter reduces deployment of extra man power for taking meter reading, payment collection and removes the entire infrastructure for electricity bill
collection system. Thus the technology saves a substantial amount of money for the service provider which is added to the electricity bill apart from
consumption. Once this additional amount is removed the consumers will be benefited and bill will be reduced to a great extent. Apart from this the
technology manage optimal load dispatch through an in built programmable load limiter to avoid grid collapse due to over load.
The system having a portable battery powered card recharging unit which can recharge the card against money for door to door card selling. It can also
recharge in terms to KWH to limit load based on seasonal condition. The card selling , supervision and training to the consumer about new technology may lead to a good business model for employment of Indian rural population where technology awareness is poor. The battery powered card recharger may be fitted on a bicycle for card recharging / selling at the consumers’ door step which may be a more effective model of business and technology promotion in remote areas. This may help to remove any unauthorized electricity connection violating the rule.
