Design and Modulation of Wind Energy Conversion System in Kouttina to be Coupled with Syrian Electrical Grid


Abstract in English

Kouttina is one of the most proper areas in Syria for building wind energy conversion system. This system could be coupled with Syrian electrical grid without expensive cost because of nearing from the grid. But the permanent changes of wind speed with no stable mode, cause different amplitude and frequency voltages differ from Syrian electrical grid amplitude and frequency. The goal of this research is to design proper wind energy conversion system for Kouttina area and control it, therefore we always obtain constant amplitude and frequency voltages equal to those of Syrian electrical grid for any wind speed and load. The proper wind turbine with its generator was chosen depending on parameters of probability mathematic function, called Wiebull Function. After that the proper control system was designed for equaling the amplitude and frequency of wind energy conversion system output with those of Syrian electrical grid. The buck -boost converter was controlled by proportional integral (PI) controller to always have DC output voltage equal to (622V). While the inverter controller was achieved by using two PI control loops, the outer loop for voltage control and the inner loop for current control. Though, three phase voltage with RMS phaser value of (220V) and frequency value of (50Hz) is achieved. To validated the correctness and effectiveness of the proposed system, it was modeled using MATLAB program. The results showed the system ability of obtaining voltage with constant amplitude and frequency and this values do not change with wind speed or load changes.
