PLC AND SCADA BASED ELCTRICITY SUPPLY SWITCHING WITH INTEGRATION OF SOLAR AND WIND ENERGY

Abstract

Among all renewable energy sources, solar photovoltaic (PV) represents a very important and reliable energy source. However, the output of the PV module is limited. The system performance in renewable energy sources is improved using DC - DC converters. Moreover, using Wind energy can also be used with solar energy to create a hybrid energy system utilizing Sun’s energy even more hence reducing the dependency on conventional sources. This Project is focused on integrating solar and Wind energy with diesel generators to the grid to act as a power backup for an industry. Switching logic is developed to switch between various solar cells and diesel generators. Parameters such as connected load, actual load, circuit breaker ratings, voltage and current ratings of transformer, solar cell, wind turbine, diesel generators are calculated to ensure their synchronization with grid. Bus Couplers are also employed to ensure safety of each and every component connected to the grid. The Ladder logic is designed in Delta WPL soft. The simulation model for power conversion of Solar cell from DC to AC and Model of Wind Turbine with the use of MPPT is implemented in MATLAB Simulink with the use of boost converter and inverter, Meanwhile Wonderware InTouch is used to Simulate various operating conditions in case of failure of mains supply.
