This paper presents a simulation study and an experimental implementation of a three-phase parallel Active Power Filter, to improve the power quality by attenuating harmonics in the current and improving the power factor. The control strategy of the Active Power Filter for this work is Indirect Control. In the first stage, the Active Power Filter is evaluated by simulation in Matlab/Simulink and then experimentally validated on a laboratory stand. On the software side, LabView was used with the NI cRIO 9039 chassis and the NI 9223 and NI 9402 modules. Both the simulation results and the experimental results demonstrated the improvement of the power quality by using the Active Power Filter.

It is not possible to speak about a complete security system without also taking into account the video surveillance system (CCTV). The reason is that CCTV systems offer the most spectacular results both in the security of goods and people and in the field of customer relations, marketing, traffic monitoring and the list can go on. With the development of the software industry the applicability of CCTV systems has greatly increased, largely due to image processing applications. The present paper, which is the continuation of an article already presented at an international conference, aims to shape the electrical characteristics of a common video surveillance system. The proposed method will be validated in two different programming environments.

Environment protection is a provocative task in any industrial business and many investments have been made for developing the best techniques in order to minimize pollution, in all its forms. Air dedusting is a main topic in steel industry and one of the solutions used is the electrostatic precipitator (ESP). This device is based on the idea of removing dust particles from a gas flow using electrostatic charge (corona effect). The energy is thus applied only to the particles, not to the gas resulting a very efficient process regarding energy consumption. In this paper a controller is proposed to be integrated in an automation system for controlling an electrostatic precipitator and all its auxiliary equipment.

This paper studies the dielectric performances of liquid silicone rubber (LSR) and LSR-SiO2 nanocomposites, in connection with dynamic mechanical analysis (DMA) results on these materials. The methodology used is based on measurements of the dielectric spectra of the real part of the complex permittivity and of the loss tangent for unfilled LSR and nanocomposite samples, in the ranges $10^-{2}-{10}^6$ Hz for frequency and $30-80^{circ}{mathrm{C}}$ for the temperature. The main contribution refers to the temperature influence on the dielectric response of the tested materials. Finally, it was concluded on the suitability of the tested nanodielectrics as substrate for wearable microstrip antennas.

Large datasets generated by smart meters are more and more frequent in electricity consumption. This paper explores and compares a couple of big data solutions to handle massive volumes of data and extract valuable insights to improve retailers’ business and consumers’ benefits. There are many smart meter data applications, but one of the most recent applications with smart meter data is related to the flexibility potential of the commercial buildings that could be traded and assessment of the benefits. There is a variety of Demand Response (DR) programs that can be implemented to electricity residential or commercial consumers. However, the successful implementation of DR programs depends on the characteristics of electricity consumers and their consumption behavior that can be found out using big data solutions such as complex libraries that free the computer’s memory by splitting the large datasets into chunks and use the concept of lazy computation and memory mapping. Thus, we propose a calculation method for evaluating the flexibilities and benefits of the commercial buildings’ owners. Reference smart meter generic data for 16 types of commercial buildings in the U.S.A. is processed to create relevant simulations, identify flexibility potential using previous studies and calculate the gains related to such DR services.

With the unprecedented development of electric vehicles that require high-power fast charging systems, wireless charging systems have not been lately of the same interest to the public and EV manufacturers as they were a decade ago. Most of the systems that are currently used are based on conductive (plug-in) charging. In fact, the situation is different: the requirements have changed lately with the proliferation of autonomous and connected vehicles operating in the air, in the water and on land (roads and factories), for which the automatic charging of batteries with no human intervention and no contact is a mandatory condition. That is why regulatory and standardization bodies around the world carry out an intense activity in the field of wireless charging. After the successful implementation of low-power wireless systems for medicine and mobile terminals, maintaining the level of the electromagnetic effects on the population within specified limits and the concept of interoperability between systems have become mandatory for high-power wireless systems. The paper draws attention to the fact that, although the standards in any field of activity are not mandatory, they represent an irreplaceable guide for both researchers and designers who develop applications to produce and market them. The paper presents the current state of standardization of wireless charging systems for electric power, both in terms of functionality and electromagnetic compatibility.

The paper analyses the influence of the nonlinearity of the magnetic circuit (and, implicitly, the possibility of saturation) on the functional and performance characteristics of the permanent magnet synchronous machine (PMSM). The comparative analysis was performed between a PMSM anisotropic and linear, and a PMSM anisotropic and nonlinear, respectively, for the same control strategy, in the PSIM programming software. Based on the results obtained, at the end of the paper, conclusions were formulated for this class of motors and recommendations were done to mitigate the negative effects generated by the saturation of the magnetic circuit as a result of taking into account its nonlinearity.
