Project Summary
Electricity plays an important role for the survival of the mankind and the growth of a nation. With the increasing human population and rapid change of standard of living, there has been a tremendous increase of using the electrical. The classic and conventional methods of generating electricity are no longer being able to fulfill the increasing electricity demands due to their increased cost and depletion of resources. Hence, growing energy demands can be met using Renewable Energy Resources (RER). The renewable energy resources are intermittent and distributive in nature. Therefore, electricity generation from these resources and it processing to make it usable for electrical appliances need power converters. This Grid tie inverter (GTI) is one of those power converters which take DC voltage from RERs and converts it to AC voltage with controlled phase, frequency and voltage to synchronize it with national grid. After synchronization the power generated from RERs can be transferred to the national grid to make the transportation of energy through existing system. There are different topologies and control algorithm to design GTI. The proposed inverter for this application is Z-sources inverter which carries some advantages as compare to voltage and current source inverters. In this final year project, we will design, simulate and implement the Z-source inverter for grid tie application.
Project Objectives
Our project is based on following objectives:
•To provide suitable power converter for integration of intermittent energy resources with grid
•To design digital control of grid connected inverter
•To synchronize the z-source inverter with the existing grid for energy transfer
•To promote renewable energy utilization.
•To develop renewable energy technology locally
•Cost effective, as it omits the usage of batteries.
Project Implementation Method
We have followed this desing meyhodology:
•Literature Review
•Design of proposed Solution
•Simulations Of proposed Solution
•Comparison of simulation results with desired output
•Hardware Implementation
•Comparison of Output with simulation Results
•Write up and delivery of project
Benefits of the Project
Our project's purpose is to meet the increasing energy demands by using grid tie inverter which utilizes renewable energy resoources.
Technical Details of Final Deliverable
We have designed grid tie inverter for 50V input so we will used a step down transformer .We have dc source in the begining which powers the z impedance network and inverter .the mosfets are turned on using pwm.lcl filter is used to avoid distortion.pid controller and pwm is made digital using fpga.
