Quality Of Electrical Energy

One of the performances of the electric power system can be seen from the quality of electrical energy. In this study, the measurement of the quality of electrical energy was carried out using a power quality meter to obtain the values of current, voltage, frequency, total current harmonic distortion and total voltage harmonic distortion in the building of the Faculty of Engineering, Universitas Bangka Belitung. From measurements on the 3 existing buildings, it was found that the measured voltage value range was still at  + 5% to - 10% of the 220 Volt secondary distribution voltage value and the frequency value was still in the range of 49.5 Hz to 50.5 Hz. The total value of voltage harmonic distortion is still below the required value, but the total value of current harmonic distortion is above the required value.

Quality Of Electrical Energy

<p>This document is a contribution to improve the quality of electrical energy in the distribution network.<br />In this article we will present a method that allows us to clean up in a very considerable way the electrical network of both harmonics and inter harmonics provoked, basically by the ultrafast switches used when controlling a PWM inverter supplying a three-phase asynchronous motor. We notice that this method can be generalized for other loads creating inter-harmonics.<br />This proposed method was simulated using the MATLAB/SIMULINK software and had given remarkable results (there is a considerable reduction in total harmonic distortion (THD) of source current from 29.52% to 0.82%)</p>

Quality Of Electrical Energy

Pandu Wicaksana, Saiful Manan, in this paper explain that the load balance on the 3 phase 4 wire distribution system is very important. Continuous load imbalances can cause a decrease in the reliability of the electric power system and the quality of electrical energy. One consequence of an unbalanced load is the presence of a current flowing in a neutral introduction. The purpose of this study is to find out and analyze the current in a neutral conductor when the load conditions are unbalanced and when balanced. Load balancing is done by manual-remote, which means that the transfer of taping at a load is done by pressing the button that has been integrated with the HMI display. This software is also responsible for displaying current output from the sensor. That way, it can be seen that the current value of the neutral conductor before and after load balancing is done. That the current value of the neutral conductor will be smaller when the load is balanced compared to when the load between phases is not balanced. Keywords: Unbalanced Load, Neutral Flow, SCADA, load balancingReferencesUtami ,Purwanti Bekti. 2016.

The Cost

The cost of any product includes the cost of electrical energy in its production. Enterprises use various methods to reduce the cost of electric energy. One of the most common methods is to reduce the loss of active power in the distribution network of an enterprise. This is achieved by compensating for distortions in the power quality of electrical energy using compensating devices. The method presented in the article offers point compensation of distortions in the power quality indicators of electric energy. Point connection of compensating devices allows their small number to be used. But, at the same time, a greater effect is achieved. The connection points of compensating devices are determined by the developed method. The method includes three stages: collecting data on consumers of electric energy at an enterprise and on the topology of the distribution electric network, analyzing the results obtained using the developed algorithm, and determining connection points using the Pareto method. Also, the developed method was compared with the classical ones according to the criterion of the ratio of implementation costs to the effect of its application.
