Control of Multilevel Inverter For Grid Tied Application
Project Area of Specialization Shared EconomyProject SummaryEnergy crises are badly effecting economic growth of Pakistan. The main reason of energy crises is rely on conventional technology for generation of electricity. To overcome these energy crises power electronic based renewable technology can be used. The efficient utilization and integration with national grid of distributive renewable energy resources is possible only by using Grid Tie Inverters. The power converters technology is growing day by day therefore the sophisticated and efficient power converters are now-a-days available for this purpose. The latest techniques used to control the grid tie inverters are based on digital processing. While the analog control techniques were being used in classical inverters. In this project grid tie inverter will be controlled by using digital control techniques and processor used will be FPGA based. This will provide flexibility within the design implementation.
Project Objectives- To provide the solution that is flexible in implementing control strategies.
- To inject neat and clean energy into grid
- To design a grid tie inverter that can be controlled through soft coding techniques.
- To provide power efficient converter for the processing of power generated from renewable energy resources.
- To develop low cast high efficiency converter for renewable energy resources.
- Review of related literature.
- Design of a symmetrical cascaded multilevel inverter (SCMI).
- Deign of controller for the prosed inverter.
- Synchronization of the proposed inverter with national grid.
- Design of Common Coupling Unit.
- Simulation of proposed design by using computer simulation tools.
- Development of Hardware Prototype to test the validity of design.
- Testing of the prototype
- Comparison of extracted results with the existing designs.
- Documentation
Benefits of the Project:
- Feasible for domestic and industrial uses to feed extra energy to national grid in case of available renewable energy resources.
- Used in industries to provide generated power to national grid during holidays if renewable energy plants are available.
- Indigenous solution so it can open doors for entrepreneurs in our country.
- Due low power rating a medium and high power converter can be developed with low cost.
Direct/Indirect beneficiaries:
- Government of Pakistan is the direct beneficiary
- Common People of Pakistan
- Entrepreneur in power sector
- Industrialist
- Schools, Hospitals, Offices and Universities
- Farmers those having solar tube-well in fields.
A digital processor based grid tie inverter will be designed. It will be able to transfer power from renewable resources like solar panels to national grid. The prototype will be build that will be a scaled version of the grid tie inverter. The designed prototype will be able to transfer at most 500 Watts and it will be scalable design. The controller designed will be implemented on FPGA Spartan 3 processor.
