Abstract
Now a day’s, population and their requirements are increasing rapidly. Hence, enhancement of reliability of electrical components in power system also increases. In wind power conversion dc capacitor plays an important role to minimize harmonics, ripple currents and voltage spikes. Hence, improving the life span and reliability of a capacitor is more important. In literature, back to back converter has been used for improving life time of a capacitor. Apart from this PI controller is also used to improving the voltage profile. In a case study 1.2 MW Permanent Magnetism Synchronous Generator (PMSG) wind turbine is considered and real field mission profiles are transformed (i.e. wind speed and ambient temperature) into thermal and current stresses to estimate the reliability of dc-link capacitor. In this paper, Maximum Power Point Tracking (MPPT) controller for DC-DC Booster converter having the Power Signal Feedback is proposed to get better reliability or life time of a dc-capacitor. In addition to this, reduction of ripple current and losses is also proposed. The proposed method is implemented in MATLAB simulation software.
