Kufa, Iraq ABSTRACT In this paper, saving energy is used to minimize the power consumption and to increase the system efficiency by using the total harmonics distortion THD with first order filter. In addition, the system is optimized which operate during the starting and steady state of the single phase. This is also called a low power consumption of system. It is the low costly and easy type of system. Therefore, the proposed system is reducing the current at the starting load and full load which lead to decrease the power losses and decrease the system power consumption. The simulation of the whole system is executed by Matlab Simulink with toolbox and programming of C++. Finally, the results of saving energy show that the system is more accurate and consume low power as compare with tradition method. Keywords: saving energy, voltage source, total harmonic distortion, electrical systems Cite this Article: Afaf Ahmed Abed, Saving Energy of Electrical Systems to Reduce the Starting Current, International Journal of Mechanical Engineering and Technology, 9(5), 2018, pp INTRODUCTION In the recent year, many researches is proposed to enhance the electrical power and to increase the active power with respect to reactive power and to optimize the saving energy based on improve the power factor with reduce the harmonics of system [1], [2], [3], [4]. When the power consumption is increased which caused ecological pollution therefore, photovoltaic energy and wind turbine are more necessary. Nowadays, a trivial proportion of whole universal power originates from renewable foundations. The nonlinearity of renewable generator will affect on control superiority, and the solar energy with global wind energy would link to the network by high electrical power system [1]. The main drawback of power generation is the non-uniform environment which caused nonlinear voltage adjustment, and lead to the distortion of power system. Previously, the saving energy is proposed by using difference methods by control of power factor and to increase the active power. Though active power filters imposed with three-phase voltage which had previously been obtainable in the methodological literature [5], editor@iaeme.com

The authors in references [9], [10], [11], and [12] suggested low power consumption on machine by using wind turbine. However, this structure system of power consumption suffers from variations of parameters and outside turbulences. Therefore, it is essential to create a strong regulator to throwaway their influence. Numerous high order methods have been advanced for mutable structure system [13-15], and tough performance [16-17], sliding mode system [18-20] in order to minimize the output power consumption. In this paper, total harmonics distortion block with first order system is used for minimizing the electrical power consumption based on voltage and current sources with harmonics filters. 2. RESULTS AND DISCUSSION The Simulink of proposed system is built in by using matlab Simulink with toolbox. Figure 1 shows the Simulink diagram of suggested saving energy.

3 Afaf Ahmed Abed The structure of total harmonic block is shown in figure 2 which consist of RMS value, mean values, and Fourier transform to produce the harmonics of current or voltage for sinusoidal waves. The voltage results can be noted in figure 3. Also, the voltage based on saving energy is better and less than the voltage provide by classical method. Figure 3 Voltage comparison Figure 4 shows the current comparison between proposed and classical method which appear that the value of current is very low and started with original point in the proposed saving energy. In contrast, the current in traditional system has high value with lagging as shown in time period between 0 to 25 second as shown in figure 4. From figure 4, the current value is 8 A while the current in classical method is 10 A which mean that the power consumption in proposed method is less than the conventional method.

CONCLUSIONS This paper exposed investigation analysis of single phase or three phase power system lengthways with saving energy Improvement and deliberated on outcome of system with harmonic distortion based on fast Fourier transform. It is noted that the power consumption is depend upon the power factor enhancement for to minimize the current at full load. Furthermore, the output current in this method can be reduced consequently, the power losses also decreased and the efficiency is increased as compared with conventional system. Here, based on the economy of process, the load with variance capability of power is worked efficiently with various evaluation of load with saving energy reserved into explanation.
