Quality Of Electric Power

An electric power system must have a high level of reliability that the system is able to provide the required supply of electrical energy continuously and with good power quality, in terms of voltage regulation and frequency regulation. Decline in the quality of electric power will make serious disruption to the operational process industry customers.Dynamic voltage restorer (DVR) is a method of power quality solutions that are used to recover the voltage drop (sag) through the injection voltage on the network. Minimum power injection method is the minimum active power supplied to the load as a result of the voltage sag compensation so as to restore the load voltage back to normal. Control of dynamic voltage restorer produces a rapid and appropriate response to be the right solution to improve the quality of electric power system. Dynamic voltage restorer series is used to improve the quality of the voltage due to voltage sag that can interfere with the performance of critical equipment or sensitive equipment. Performance Series DVR is shown as an interruption of the voltage sag caused by a short circuit or some disturbance of the phase and three phase power system.

Quality Of Electric Power

Harmonics of power system seriously affected the quality of electric power. Active Power Filter (APF) [ which overcomes the shortcomings of passive filter (PF) has become main technology to suppress harmonic. In this paper, development history, key technology, problems and trends of APF are mainly analyzed and reviewed. With development of key technology of APF, it will have a better application prospect.

A Value

The study of electric power flow analysis (Load Flow) is intended to obtain information about the flow of power or voltage in an electric power system network. This information is needed to evaluate the performance of the power system. Electrical power flow problems include calculating the flow and system voltage at certain terminals or buses. The benefits of this power flow study are to find out the voltage at each node in the system, to find out whether all the equipment meets the specified limits to deliver the desired power, and to obtain the original conditions in the new system planning. This study is divided into two: the analysis of data when the conditions have not been added wind turbine and after the addition of 300 kW wind turbine with software power station ETAP software 12.6.0 and the Newton-Raphson method will be used in analyzing the power flow of the electric power system. Based on the results of the tests, it is found that the overall value of losses for power flow before the addition of DG is 0.031 MW and 0.037 Mvar, for the voltage drop with the lowest percentage, namely on bus 10 with a percentage of 96.45 for the 0.4 kV system and the 20 kV system on bus 19 with a percentage of 99.03, the largest% PF load was in lump 1 with 98.64 and the smallest% PF was in lump7 with a value of 84.92. The short circuit data value on the 20 kV bus system at Andalas University before the addition of DG with 3-phase disturbances averaged 13.354 A, 1-phase disturbances averaged 3.521 A, 2-phase disturbances averaged 11.719 A and 2 ground phases of 12.842 A Whereas for the value of power flow after the addition of DG in the form of the wind turbine of 300 kW the overall value of losses is 0.032 MW and 0.042 MvarAR, for the voltage drop with the percentage for voltage drop with the lowest percentage is bus 10 with a percentage of 96.63 for system 0, 4 kV and a 20 kV system on bus 14 with a percentage of 98.1, the largest% PF load is in lump 1 with 98.64 and the smallest% PF is in lump7 with a value of 84.92. The short circuit data value on the 20 kV bus system at Andalas University after the addition of DG with 3 phase disturbances has an average value of 13.354 A, 1 phase disturbance averages 3.523 A, 2 phase disturbances average 11.737 A and 2 phases ground is 12.059 A For the source in this system, after the addition of DG, there was a change in the% PF of the PLN grid, namely 79.53 and the wind turbine -83%.

Quality Issues

The term power quality is inescapable when it comes to Electric power system. The main intent of the researchers and different organizations all over the world is to provide the consumers with quality power. Practically, it is difficult to achieve quality power as there are number of issues associated with Electric power system called as power quality problems. Harmonics, transients, use of non linear loads, interruptions etc. are the factors which cause disturbances in the electric power system and thus leads to the deterioration in the quality of power. These disturbances are the major challenges to the power quality and must be analyzed properly before mitigating them. The paper has put emphasis on the major disturbances in the power grids. The paper is also considerate about the causes and effect of these disturbances in the power grids.
