Power quality improvement of eight bus system using TCTC

If the reactive power of the load is changing rapidly, a suitable fast response compensator is needed. SVC and TCTC (Thyristor controlled tap changer) are two such compensators belonging to FACTS devices. A model for the Thyristor tap changer has been designed to improve the voltage level at the load end. Smooth reactive power control is achieved by varying the firing angle of TCTC system. The simulation results of eight bus TCTC system are presented.

Design and Analysis of Grid Connected PV Generation System

As there is a power shortage across any country, usage of renewable energy sources is being encouraged nowadays. This energy produced has to be properly synchronized with the grid to ensure safety and energy continuity. In this paper, the standard procedure for grid interconnection is discussed and the impact of not following the procedure is shown using the voltage and current waveforms. Later a step by step procedure for designing a MPPT algorithm based PV generation system connecting to the grid is developed. The developed system feeds a common load, as the micro grid systems feeds the local loads. The system takes care of all the specified guidelines while feeding the load, which is proved by using the voltage and current waveforms. Therefore this paper acts as guide in developing renewable energy based grid connected system.

Design of a grid connected system using proteus software

Nowadays the usage of renewable energy source is being encouraged in developing countries to meet the power shortages. The produced supply must follow the precised guidelines, so that the supply can be connected to the grid system. In this work, a grid connected module is developed using a DC - DC converter and conventional H - bridge inverter. The aim of the proposed methodology is to reduce the size of the filter used across the inverter and it is achieved. This is done by applying SPWM wave to the DC - DC SEPIC converter and the H - bridge inverter is operated at normal power frequency.
