The Impact

Non linear load harmonics cause, Air Conditioning is one of the main types of inverters that generate non linear load harmonics. Harmonics on the Air Conditioning so that the reduction must not interfere with the quality of power on the system and network. The ability of an Air Conditioning unit to cool a room can be known as Coefficient Of Performance (COP). This can be seen from the comparison between the heat energy required to cool the room with the electric energy used on the unit. In this case you will know the impact caused by the reduction of the harmonics of the COP. Reduction of harmonics used in this study using 16 F capacitor which also serves as a power factor improvement. The results obtained after using the capacitor found impairment harmonic currents (IHDi). After the measurement of the COP also increased from 2,740 becomes 3,176. This proves that the capacitor also function besides improving the power factor can reduce the harmonics an improve the COP.

The paper presents the analysis of harmonic distortion when non-linear load is connected in different phases of power system with STATCOM for singly excited induction generator system with wind turbine as prime mover. Now-a-days due to the drastically increased in use of non linear loads causes many power quality problems in power system network. Those problems are classified as reactive power problems, harmonics, voltage sags and swells. Out of these problems harmonic problems are major concern. Custom power devices proposed for mitigation of power quality in network. For compensation of harmonic, static compensator (STATCOM) is used. The paper presents the compensation of harmonic power quality issues using STATCOM for the system with singly-excited induction generator feeding non-linear load connected in different phases. STATCOM is controlled using synchronous reference frame theory to produce pulses to switches of STATCOM sensing the input parameters. Proposed concept was developed using MATLAB/SIMULINK software and results are presented for non-linear load connected in different phases of the power system. THD analysis was shown for source current and load current for different cases.

Flow Of Information

The upcoming advanced electric grid or smart grid is define as the intelligent junction of smart devices making a power system featured by the next level advancement of flow of information and electricity in two way. In this work we have come out with the better quality of energy generated at transmission side which also involves the implementation of fuzzy controller. As a goal this work is possessing working of any 2 non conventional resources i.e. wind and PV solar panel to run any non linear load by providing the controlled power to it through fuzzy controller. A general experimentation was performed to examine the current condition of art of smart grid, and removal of disturbances and their affect on power quality. Which is due to the complications, huge heterogeneity of smart grid and high amount of information to be processed, computational techniques are enabling technologies for its advancement and success in future. Hence the motive of this work is to implement fuzzy controller in combination with non conventional resources in smart grid to the production of needed amount of electricity to make the non linear load work accordingly. Different artificial technologies give support to the development of power system.

Priyo Sasmoko, in this paper explain that the need of electric power recently progressively complex, not only the requirement of availability of electricity, but the quality of energy have become prime facie demand. Studies of electricity quality have been conducted by many experts, one of them is about harmonic. Harmonic represent waving current or tension which is tension distortion at electric power system mains so that can result unideal waveform. The study of harmonic required appliance or obyek which need to be checked. In this research Simulator Generator Harmonik is made  a harmonic generator module which can deputize the appliance or obyek yielding harmonic with harmonic component and the THD which can be varried. This module works by dividing one cycle of mains become some slots so it can be got harmonic component as desired. To change the THD,a variation of linear load is used so that the ratio of non-linear load current can be varried. Keywords : Simulator, Harmonic component, THD
