The main purpose of this paper is detection of fault in PV(Photovoltaic) system. Faults are in the form of DC side short circuit faults which consist of photovoltaic panels which is connected in series or parallel. Under low irradiance conditions fault detection is very difficult so such faults detect by using wavelet and fuzzy algorithm. If this faults are not detected then faults can gives lower output energy and panel can be damage. The proposed method of fault detection is totally based on Wavelet transformation and fuzzy logic system.

This paper deals with the simulation of a unified series shunt compensator aimed at examining its capability in improving power quality in a power distribution systems. The USSC simulation comprises of two 12- pulse inverters which are connectedin series and in shunt to the system.A generalized sinusoidal pulse width modulation switching technique is developed in the proposed controller design for fast control action of the USSC. Simulations were carried out using the UPQC to examine the performance of the USSC model. The power quality problems are many as voltage sag and voltage swell exist in the system so in this project we are going to design unified series shunt compensator for number of issue such as harmonic elimination, voltage flicker, voltage sag , voltage unbalance mitigation. The USSC has moderated a few power quality issues giving better execution.
