This thesis will present a short list of power quality problems, their characteristics, and the traditional methods used to solve them in table 11 the practical scope of this work is restricted to studying voltage sags, voltage swells, flicker and harmonic distortion all these are solvable through dstatcom. The dynamic response of d-statcom is observed by changing the reference reactive current simulation results compared with conventional pi controller are given key words: reactive power compensation, power quality conditioner, d- statcom, fuzzy-pi 1 compensator”, ph d thesis, georgia institute of. Comparative study of pi controlled and fuzzy logic controlled dstatcom for improving the power quality and dynamic performance of a distribution power system is simulated using simpowersystem in matlab/simulink environment in this thesis, two control strategies of dstatcom are developed and compared: 1. The nodal voltage solutions and power flow solutions are explored with and without distribution static compensator (dstatcom) switching sequence of the dstatcom for different seasons is computed and the reactive power reallocation is done for the dn phd thesis, arizona state university, 2015 3. In this dissertation a three-bus, radial distribution system is proposed to be used as a benchmark for the study of power quality problems (pqps) and their compensation to mitigate pqps in distribution systems, custom power systems (cups) devices such as distribution static compensator (d-statcom), dynamic.

Abstract this thesis presents an idea of pv cell or battery based dc to dc boost converter which is served to a voltage source converter (vsc) for enhancement of quality of power a synchronous reference controller is suggested using distribution static compensator (dstatcom) in a 3-phase 4-wire. The main purpose of the distribution static compensator (d-statcom) is to protect the consumer from supply voltage sag, voltage swell as well as provide a unity power factor at the utility for different load power factor values this paper analyses the power flow inside the d-statcom in several cases the analysis. I certify that an examination committee met on 15 december 2005 to conduct the final examination of shamsul aizam zulkifli on his mater of science thesis entitled simulation of linear feedback control of d-statcom for voltage sag mitigation in accordance with universiti pertanian malaysia (higher degree) act.
It ultimately leads to better design of mitigation devices like dynamic voltage restorer (dvr), distribution static synchronous compensator (dstatcom) and unified power quality conditioner (upqc) to alleviate various power quality related problems the main objective of this thesis is to develop a. Abstract: a power quality problem is an occurrence manifested as a nonstandard voltage, current or frequency that results in a failure or a mis-operation of end user equipments utility distribution networks, sensitive industrial loads and critical commercial operations suffer from various types of outages and service.
The d-statcom, which consists of a thyristor-based voltage source inverter, uses advanced power electronics to provide voltage stabilization, power factor correction, harmonic control and a host of other power quality solutions for both utility and industrial applications this thesis describes the. Of applications it is the basic device that will be studied in this thesis pcc load source d-statcom figure 25: distribution grid with a d-statcom e- statcom the energy storage static synchronous compensator (e-statcom), showed in figure 26, has the same structure as the d-statcom it can be used for the. Study, analysis and simulation of a static compensator d-statcom for distribution systems of electric power compensation of reactive power with a facts device based voltage inverter d-statcom a complete simulation of statcom and sssc, magister thesis, university of new brunswick, 2003 8 pradeep k.
