“…(Debruyne et al, 2012) have compared the effects of harmonic voltage distortion and harmonic content phase angle on the overall motor efficiency of line-start permanent magnet machines (LSPMM) and IM. The impacts of voltage unbalance and distorted supply on the performance of IMs have been studied by (Donolo et al, 2016), (Neves et al, 2016) and (Deleanu et al, 2019). (Lerch and Rad, 2016) have studied the power losses in IMs supplied with distorted voltage, same study has been done by (Zhang et al, 2017) and (Donolo et al, 2020) when IM is supplied with unbalanced and distorted voltage.…”

Voltage distortion has become one of the most common power quality problems in industrial applications, which has gained a great deal of attention in recent years because of the widespread usage of non-linear loads. Three-phase induction motors are widely used and one of the factors that confirm the reduction of their performance is the presence of harmonics in their voltage supply. In this paper, the impact of non-sinusoidal supply voltages on the steady-state performance of different NEMA designs of squirrel cage induction motors (SCIMs) is presented. It presents the analytical modeling based on the equivalent circuit taking into consideration the skin effect impedance that incorporates the skin effect on the rotor bars, which is used to investigate the motor performance under such conditions. The importance of this study is that it compares all NEMA designs in terms of electromagnetic torque, efficiency, losses, power factor, stator and rotor currents, and derating factor under a distorted supply voltage that is polluted by the most significant odd harmonic orders at adjustable levels in the range of (0 25) % of THD v %. The obtained results are compared and validated with the system employed by using MATLAB/Simulink software. The simulation and the analytical model results have shown good accuracy.

“…The study of the influence of the parameters of nonsinusoidal and unbalanced modes on induction motors has been engaged in for a long time, since induction motors are the most used electrical equipment [1][2][3][4][5][6][7][8][9][10][11]. A special standard specifies the operating conditions for induction motors with unbalanced voltages [12].…”

The parameters of electrical network modes do not correspond the requirements GOST 32144-2013 of Russian and the National technical regulation of Vietnam. In real operating conditions in electrical networks in non-sinusoidal and unbalanced modes there are harmonic components of voltages and currents as well as voltages and currents of negative sequence. They cause additional losses of active power, which leads to additional heating and causes premature aging of the insulation, and as the result, the reduction in the service life of induction motors. Currently, we see that the process of formation of intelligent electrical power systems is underway. Systems for continuous monitoring of power quality indices and parameters of electrical systems modes are being developed. These systems can be supplemented with programs for calculating characteristics that issue the warning when the unfavorable influence of the parameters of non-sinusoidal and unbalanced modes is detected on various electrical equipment of both electrical power systems and consumers of electrical energy. The paper provides an overview of the characteristics used to analyze, assess and predict the influence of poor power quality associated with non-sinusoidal and unbalanced of currents and voltages on induction motors. A computer program was developed to calculate these characteristics. The program was used to study the influence of non-sinusoidal and unbalanced modes on the induction motors of the coal sorting plant of the Vietnamese company “Cua Ong-Vinacomin”.

The electric vehicle deployment, due to the plans defined according to the energy transition objectives, produces new challenges for the electrical system. These challenges are associated with the charging infrastructure of these vehicles since they require a high current during specific periods, which can increase losses in the network, overload the lines, or cause voltage drops that affect the system’s stability. To solve these challenges, one of the possible solutions is the investment in new network infrastructure to face the increase in demand, such as the construction of new transformation centers or new medium and low-voltage lines. However, in the case of rural networks with a small number of users, these investments may not be viable. This article analyzes the possible impacts of connecting electric vehicles in a rural low-voltage network located in a Spanish municipality, as well as possible implementable solutions that do not require investment in new infrastructure. The number of connected vehicles has been calculated based on the national plan for 2030, and the network model used is based on actual data provided by the distribution company that operates in the area.
