    Abstract: The low performance of power supply in the transmission network is as a result of voltage instability, this is overcome by improving voltage stability in Nigerian 330kv transmission network using intelligent solid state var compensator (SSVC). It is achieved in this procedure by running the load flow from the characterized data thereby locating the... Show More

    Abstract: Building integrated wind turbine are considered as part of a group of technologies that are suitable for domestic micro-energy generation. Darrieus and Savonius turbines work efficiently in the urban environment at low wind speed, the Savonius rotor is self-starting and creates high torque but has low efficiency, while the Darrieus rotor is very ef...

    Abstract: The power quality problems are more and more serious in the power system. The harmonics and the three-phase imbalance have a greater impact on the line loss of power grid. We focus on the power losses in cables and transformers with unbalanced load in current harmonics basing on the equivalent resistance method. The impact caused by the skin effect... Show More

    Abstract: With the exponential evolution of the complexity of reconfigurable logic circuits, the Field Programmable Gate Array (FPGA) becomes an attractive element to realize reconfigurable virtual instruments, due to their inherent flexibility. The simple bus architecture allows us to use pre-exist IP Cores (IP Cores) in VHDL and interconnecting them, also ... Show More
