Investigate and Improve the Reliability of Small Size Wind Energy Conversion Systems Connected to the Network

With the increasing expansion of electronic power converters in industrial applications, converter reliability.Power electronics have become very important. Electronic converters as intermediaries in systems Power generation from PV and Wind is also important in electrical drives and the aerospace industry. This article introduces comprehensive methods for assessing reliability. Methods reviewed Used for power extraction systems from WECS wind energy based on PMSG permanent magnet generator Placed. In these systems, it is usually a diode rectifier with a step-up converter and inverter on the side The network is exploited. The task of the inverter on the network side is to stabilize the DC link voltage and adjust the reactive power. The amplifier converter is also responsible for regulating the output voltage of the rectifier in order to obtain maximum power. in this Thesis uses both ordinary incremental inverter and interleave increment inverter and the capability Reliability is analyzed.
