The inrush currents which generated at the energization moment of an electric transformer can reach high values and cause some abnormal problems in the power system, and the sympathetic inrush current is produced in an electrical network during the energization of a transformer with the existence of other already supplied transformers. The present work has the purpose of eliminating these transient inrush currents. So this paper presents a data acquisition system based on dSPACE board 1104, and a laboratory setup experiment to measure the sympathetic inrush current. Moreover, a control switching to mitigate the sympathetic inrush current in a 2 kVA transformer will be developed and applied experimentally in the laboratory and also in the simulations. This control strategy is performed by considering the residual flux at the opening instant of related circuit-breaker. A comparative study is carried out showing the validity of the mitigation technique.
变压器通电时产生的涌流会达到很高的值,引起电力系统的一些异常问题,而变压器通电时在电网中产生的共感涌流是在已有变压器存在的情况下产生的。本工作的目的是消除这些暂态涌流。为此,本文提出了一种基于dSPACE板1104的数据采集系统,并进行了实验装置实验,对共感涌流进行了测量。此外,还将开发一种控制开关,以减轻2kva变压器的交感浪涌电流,并在实验室和仿真中进行实验应用。该控制策略考虑了相关断路器开断瞬间的剩余磁通。对比研究表明了该缓解技术的有效性。

In this paper, a nonlinear control strategy of the Induction Motor (IM) which associate an input-output linearizing control conception under a PWM inverter with a new nonlinear extended observer design. At first, a nonlinear control performed using a nonlinear feedback linearization technique that controls separately the flux and the speed. Secondarily, a new extended observer approach relies on the Mean Value Theorem (MVT) using the sector non-linearity to exhibit the error dynamics as a convex theory association of known matrices with time-varying parameters after representing the nonlinear system as a Takagi-Sugeno (TS) model. Utilizing the Lyapunov approach, the stability terms are expressed in form of linear matrix inequalities (LMIs), the observer gain is gotten by solving the LMIs. Finally, the proposed approach is applied to IM machine through an illustrative simulation to affirm the effectiveness of the concept.
本文提出了一种异步电动机的非线性控制策略,将PWM逆变器下的输入输出线性化控制概念与一种新的非线性扩展观测器设计相结合。首先,采用非线性反馈线性化技术分别控制磁链和速度,实现非线性控制。其次,在将非线性系统表示为Takagi-Sugeno (TS)模型后,利用扇形非线性的中值定理(MVT)将误差动力学表现为具有时变参数的已知矩阵的凸理论关联,提出了一种新的扩展观测器方法。利用李雅普诺夫方法,将稳定性项以线性矩阵不等式的形式表示,通过求解线性矩阵不等式得到观测器增益。最后,通过实例仿真将该方法应用于IM机,验证了该方法的有效性。

This paper introduces an effective design and control of a two-stage standalone photovoltaic system consisting of a DC-DC boost converter as the first stage and a single-phase full H-bridge inverter as the second stage. The DC-DC converter controlled by Perturb and Observe MPPT to achieve maximum electric power under different weather conditions. Moreover, the full H-bridge inverter topology along with two control loops are used as a link between the system and the load. To mitigate noises that could occur in both voltage and current, a second order passive Inductor Capacitor(LC) filter is conceived. Implementation of the system is done by Matlab/Simulink Software and relevant results are discussed.

The present paper aims to propose an implement of perturb and observe (P&O) technique for photovoltaic systems using a boost converter driven by Arduino MEGA 2560 in a view of providing an efficiency improvement of PV system. This method has been further characterised by considering its fast ability of tracking the (MPPT) and reducing the computational time using digital controls of the Arduino MEGA 2560 microcontroller. In the present paper, we proposed a simple method for implementing the P&O technique by interrupts of the Arduino MEGA. Indeed, the (P&O-MPPT) technique implementation technique has been carried out with regard to the usage of the developed costless instruments. oreover, the regulation of (P&O) MPPT technique which is responsible for the switching of MOSFET exists in the dc-dc boost converter so that it can extract the MPP. This work has been therefore simulated by Matlab/Simulink and programing by C code, and consequently, in a view of the above, the (P&O) algorithm has been applied in a real time by Arduino MEGA to decrease the cost of the MPPT controller and to show the results of the performance for the proposed technique.
本文旨在利用Arduino MEGA 2560驱动的升压变换器实现光伏系统的扰动与观测(P&O)技术,以期提高光伏系统的效率。该方法通过考虑其快速跟踪(MPPT)的能力和使用Arduino MEGA 2560微控制器的数字控制减少计算时间而进一步表征。在本文中,我们提出了一种简单的方法,通过Arduino MEGA的中断实现P&O技术。事实上,在使用开发的无成本仪器方面,已经开展了(P&O-MPPT)技术实施技术。此外,负责MOSFET开关的(P&O) MPPT技术的调节存在于dc-dc升压变换器中,从而可以提取出MPP。因此,这项工作已通过Matlab/Simulink进行了模拟,并通过C代码进行了编程,因此,鉴于上述情况,(P&O)算法已被Arduino MEGA实时应用,以降低MPPT控制器的成本并显示所提出技术的性能结果。

In this paper, an experimental platform based Arduino microcontroller and GSM card has been performed and proposed for power system protection education. The experimental work carried out consists of three parts: the first part is dedicated to demonstrate the possibility of adapting and using the Arduino board to measure the different electrical quantities such as voltage, active power, current and power factor. The second part is dedicated mainly in adapting and using the Arduino board to demonstrate the coordination principle between primary and secondary protection. While the third part aims to simulate the basic principle of the SCADA system, by remote control of a contactor supplying a load. In order to carry out this task, a GSM card associated with Arduino board is used, thus making it possible to remotely control the opening and closing of the contactor and also to detect the fault in the load by receiving a message.

This work deals to improve the efficiency of the photovoltaic panel efficiency by water cooling. This cooling system uses 50 g/s of water flow rate which circulates in a closed circuit between an insulated tank and the back side of the photovoltaic panel. Considering the climatic parameters of a typical summer day in Ghardaia (south of Algeria), this system ensures a maximum PV panel temperature of $34. 9^{o}C$ at 1.30 pm. Furthermore, the electrical efficiency of the cooled PV panel increases from 13.22 to 14.51%, from 11.47 to 14.31% and from 13.11 to 14.56%, respectively, at 8 am, 1 pm and 6 pm, compared to the situation of uncooled PV panel, exposed at the same climatic conditions. Moreover, this cooling system offers a maximum improvement of 25% at midday. In addition, the temperature field on the PV panel is almost homogeneous except at the junction box of electrical wires, where the PV panel heats locally.

Numerical Study of Low Gain Avalanche Detector Performance 低增益雪崩探测器性能的数值研究
Pub Date : 2018-12-01 DOI: 10.1109/CCEE.2018.8634532

In this paper, we present a new ultra fast detector called Low Gain Avalanche Detector (LGAD) with low internal gain. The LGAD is fabricated with conventional APD technology with a modified doping profile, in the multiplication region, which affects the device performance such as: breakdown, multiplication gain and noise factor. For this reason, a numerical method based on Newton-Raphson calculation is proposed to estimate the electrostatic potential and electric field models of low gain avalanche detectors (LGADs) in order to investigate their performances. These models have been validated by their agreement with TCAD numerical simulation results. The effect of Boron doping profile, with different doses in the multiplication region, on the LGAD electrical performance is studied for various device structures in order to extend the device capability to its limit. In addition, LGAD devices are simulated for different temperature considering the effect of the temperature on the multiplication gain.
本文提出了一种具有低内部增益的超低增益雪崩探测器(LGAD)。LGAD是用传统的APD技术制造的,在倍增区添加了修改的掺杂剖面,这会影响器件的性能,如击穿、倍增增益和噪声因子。为此,提出了一种基于牛顿-拉夫森计算的数值方法来估计低增益雪崩探测器(LGADs)的静电势和电场模型,以研究其性能。这些模型与TCAD数值模拟结果吻合较好。为了将器件性能扩展到极限,研究了在倍增区不同剂量的硼掺杂谱对不同器件结构LGAD电性能的影响。此外,还考虑了温度对倍增增益的影响,对不同温度下的LGAD器件进行了仿真。

The LGAD is fabricated with conventional APD technology with a modified doping profile, in the multiplication region, which affects the device performance such as: breakdown, multiplication gain and noise factor. For this reason, a numerical method based on Newton-Raphson calculation is proposed to estimate the electrostatic potential and electric field models of low gain avalanche detectors (LGADs) in order to investigate their performances. These models have been validated by their agreement with TCAD numerical simulation results. The effect of Boron doping profile, with different doses in the multiplication region, on the LGAD electrical performance is studied for various device structures in order to extend the device capability to its limit.
