A modern DC electric railway traction power supply system consists of a twelve-pulse rectifier which will cause 11th and 13th order harmonics to be injected into the power system. A shunt active harmonic filter (SAHF) is proposed to mitigate the harmonics at medium voltage (MV) line. SAHF control strategy usually consists of three core elements which include reference current generation, DC-link feedback control, and current control and gate signal generation. This paper proposed a distinct time domain-based control strategy with DC-linked feedback reference current compensation method which has a simple topology, low mathematical complexity, and fast response time. Detailed performance analysis of SAHF is carried out in the parameter selection process whereby the effects of each parameter are discussed. The implementation of SAHF in traction power supply substation (TPSS) is simulated using MATLAB/Simulink. The harmonic analysis result has shown the effectiveness of the proposed SAHF in reducing THDv, TDDi, 11th order IHDi, and 13th order IHDi of TPSS MV line to levels lower than 4.61%, 1.03%, 0.96%, and 0.67% respectively which are compliant with the limits recommended by IEEE std. 519–2014.
现代直流电气化铁路牵引供电系统由一个十二脉冲整流器组成,它将产生11次和13次谐波注入电力系统。提出了一种并联有源谐波滤波器(SAHF)来抑制中压(MV)线路的谐波。SAHF控制策略通常由参考电流产生、直流链路反馈控制、电流控制和栅极信号产生三个核心要素组成。本文提出了一种基于不同时域的控制策略,采用直流链接反馈参考电流补偿方法,具有拓扑简单、数学复杂度低、响应时间快等优点。在参数选择过程中,对SAHF进行了详细的性能分析,讨论了各参数的影响。利用MATLAB/Simulink对该系统在牵引供电变电所中的实现进行了仿真。谐波分析结果表明,该方法可有效降低TPSS中压线路的THDv、TDDi、11阶IHDi和13阶IHDi,分别低于4.61%、1.03%、0.96%和0.67%,符合IEEE std. 519-2014推荐限值。

The power system stabilizer (PSS) plays a key role in multi-machine power systems. The main objective of PSS is to provide damping of the rotor oscillations, whenever there is a transient disturbance. In this paper, eigenvalues and participation factor are used to identify the oscillatory modes in a multi-machine system without and with PSS. The transient simulation is carried out to validate the steady state model. The proposed methods runs for N-number of buses and M-number of generators. The study system comprises a 4-generators and 10-buses two area multi-machine system. The results obtained on the study system show that oscillatory response of speed deviation and rotor angle is well damped with PSS.

Underground cables are used for electrical power transmission from the power system grid to substations and consumers especially in city and densely populated areas such as railway stations, hospitals, airports etc. In underground cable systems, cables are positioned under the surface. Generally, the process of detecting the underground cable fault is complex, time-consuming, and costly. When any fault occurs, identifying, and tracking the source of the fault is complicated because the entire line is to be drilled to inspect the cable line fault. This paper presents a microcontroller-based underground cable fault identification and tracking system using GSM and GPS techniques. The purpose of this research is to develop a microcontroller-based smart and time-convenient design for the detection of the underground cable fault. This research aims to find out the distance of cable fault from the control room of the base station in kilometer using GSM and GPS service providing an alert of the exact fault location for repairing the cable fault.
地下电缆用于电力系统电网向变电站和用户的电力传输,特别是在城市和人口稠密的地区,如火车站、医院、机场等。在地下电缆系统中,电缆位于地表以下。一般情况下,地下电缆故障检测过程复杂、耗时长、费用高。当发生故障时,由于需要钻取整条线路来检查电缆线路故障,因此对故障源的识别和跟踪非常复杂。介绍了一种基于GSM和GPS技术的基于单片机的地下电缆故障识别与跟踪系统。本研究的目的是开发一种基于单片机的地下电缆故障检测的智能、便捷的设计方案。本研究的目的是利用GSM和GPS业务,以千米为单位,找出电缆故障点到基站控制室的距离,为电缆故障的修复提供准确的故障位置预警。

Internet of things (IOT) and Machine Learning (ML) techniques have achieved quite high standards with the availability of high-speed GPU's and wide range of applications in real world. Both of them are shaping the way we live, travel, work and communicate. Medication in India is the core power of the Economy but, it's quite expensive. This paper aims at an attempt to deploy these IOT and ML techniques for Automating Insulin Drug Delivery (AIDD) for comatose patients. The main focus is to replace the existing Insulin Delivery Systems which are costly and limited to only certain hospitals, with a cost friendly and smart system which incorporates IOT and Machine learning with good accuracy and a very affordable price. In this the rotor system is designed and presented which is employed to deliver the required amount of insulin. The rotation of the designed rotor system is controlled by a motor. In order to make the system more flexible, bimodal operation is developed using IOT which enables either manual or automatic mode. To fix the optimal ML technique, the various machine models such as Linear Regression, Decision Tree and Random Forest is employed to predict insulin dose amount that must be given to the patient by examining his/her condition. This method makes it possible to treat a diabetic patient remotely, without the need of a physical person.
随着高速GPU的可用性和现实世界中广泛的应用,物联网(IOT)和机器学习(ML)技术已经达到了相当高的标准。它们都在塑造着我们生活、旅行、工作和交流的方式。药物在印度是经济的核心力量,但是非常昂贵。本文旨在尝试部署这些物联网和机器学习技术,为昏迷患者自动化胰岛素给药(AIDD)。主要重点是取代现有的昂贵且仅限于某些医院的胰岛素输送系统,使用成本友好且智能的系统,该系统结合了物联网和机器学习,具有良好的准确性和非常实惠的价格。本文设计并提出了转子系统,用于输送所需量的胰岛素。所设计的转子系统的旋转由电机控制。为了使系统更加灵活,使用物联网开发了双峰操作,可实现手动或自动模式。为了确定最优的ML技术,采用线性回归、决策树和随机森林等各种机器模型,通过检查患者的病情来预测必须给患者的胰岛素剂量。这种方法使远程治疗糖尿病患者成为可能,而不需要一个人。

Non-linear controller such as the Hysteresis controller and linear PI controller was also used to realize the controller for a voltage source converter. From both the controller it is found that they require detail mathematical models for their Implementation. Implementation of a mathematical model sometimes does not give accurate result and it may also happen that the model does not reflect the real-time system features. So these days Fuzzy logic controllers are being implemented in the electronics field for the Implementation of controllers.

A practical energy management method for a small-scale hybrid wind-solar-battery power system is proposed in this research. To evaluate the performance of a hybrid micro grid, dc-dc converter and controllers were built together with wind and solar power conversion and energy storage technologies. The hybrid power system is configured to run at unity power factor, and the Maximum Power Point Tracking (MPPT) methodology is used to control the output voltage as the weather shifts. An energy management system maintains the power balance for fluctuations in renewable energy sources power generation as well as load demand fluctuations. However, this proposed system improved reliability; reduce voltage fluctuations due to various irradiations and wind speed combined with the main grid. The battery with a DC-DC converter is incorporated into the main power system by a 3– - inverter and also the battery is used to store the energy in normal condition and deliver the energy when not available from the sources.

Global warming, pollution, and other environmental issues are becoming more and more acute. The environmental effects caused by transportation sectors are intensifying because of rising traffic congestion around the world. Electric vehicles (EVs) are becoming more popular around the world. EVs are a promising technology for dramatically reducing the environmental stress of automotive transportation. EVs have the potential to reduce the use of fossil fuels, but obstacles such as limited range, charging time, and a shortage of charging stations have slowed their adoption. This paper presents a solution to the slow charging of electric vehicles by designing a 48V onboard fast charging system for EV that operates in the Constant Current-Constant Voltage (CC/CV) mode and charges the battery in around an hour. The designed charger may be plugged into any single-phase AC socket to charge the 48V lithium-ion battery used in the EVs. A full-bridge phase-shifted (FBPS) dc-dc converter for galvanic isolation and dc-dc conversion. The FBPS DC-DC converter is designed, and the model is then built, tested and investigated in MATLAB/Simulink. The simulation results confirmed that the battery is being charged in CC-CV mode and the charger is able to charge the battery in one hour if 100 Ampere current is delivered to the 100Ah battery for one hour.
全球变暖、污染和其他环境问题变得越来越尖锐。由于世界各地的交通堵塞日益严重,交通部门造成的环境影响正在加剧。电动汽车(ev)在全球越来越受欢迎。电动汽车是一项很有前途的技术,可以显著减少汽车运输对环境的压力。电动汽车有可能减少化石燃料的使用,但有限的续航里程、充电时间和充电站短缺等障碍阻碍了它们的普及。为解决电动汽车充电缓慢的问题,设计了一种48V的车载快速充电系统,该系统工作在恒流-恒压(CC/CV)模式下,充电时间约为1小时。设计的充电器可以插入任何单相交流插座,为电动汽车使用的48V锂离子电池充电。用于电流隔离和dc-dc转换的全桥移相(FBPS) dc-dc转换器。设计了FBPS DC-DC变换器,并在MATLAB/Simulink中进行了建模、测试和研究。仿真结果证实,电池以CC-CV模式充电,如果向100Ah电池输送100安培电流1小时,充电器可以在1小时内完成充电。

Voice recognition has been advancing at a fast rate. Many cases involving edited audio clips and incorrect identity claims are reported on a daily basis. Due to the growing importance of information processing technology, it becomes easier and easier to identify people by their voices. Voice recognition consists of detecting a user's identity based on characteristics of their voice. It is a widely applied form of biometric recognition in the world, particularly in fields where security has a high priority. The deep neural networks were used as feature extractor alongside classifiers, but they haven't been completely trained due to the success of deep learning. While such methods are extremely efficient, they still require manual attention. Especially in DNN, interactivity between people and machines is essential. This is where the art of voice recognition comes from. In addition to their application in speech recognition, deep neural networks have demonstrated their potential to be used for voice recognition as well. They provide an efficient implementation of complex nonlinear models for learning unique and invariant data structures. The main contribution of this work is to provide a brief overview of the field of deep neural networks and voice recognition, describing its system, underlying approaches, and challenges.
语音识别技术一直在快速发展。每天都有许多涉及编辑音频片段和错误身份声明的案件被报道。由于信息处理技术的日益重要,通过声音来识别人变得越来越容易。语音识别包括根据用户的语音特征来检测用户的身份。它是世界上广泛应用的一种生物特征识别形式,特别是在安全性要求很高的领域。深度神经网络与分类器一起被用作特征提取器,但由于深度学习的成功,它们还没有得到完全的训练。虽然这些方法非常有效,但它们仍然需要人工关注。特别是在深度神经网络中,人与机器之间的交互是必不可少的。这就是语音识别技术的由来。除了在语音识别方面的应用之外,深度神经网络也展示了它们在语音识别方面的潜力。它们为学习唯一和不变的数据结构提供了复杂非线性模型的有效实现。这项工作的主要贡献是提供了深度神经网络和语音识别领域的简要概述,描述了其系统,底层方法和挑战。

A Novel Maximum Power Point Tracking (MPPT) Algorithms has been designed for the Photovoltaic System (PV) to overcome the effect of partial shading condition using Ant Lion Optimizer (ALO) algorithm. The conventional Algorithms has been failed to track the peak point for variable atmospheric conditions. The novelty of this work is the Ant Lion Optimizer (ALO) algorithm has been proposed for MPPT which has the ability to perform under variable atmospheric conditions. The detailed simulation and experimental work has been carried out on ALO algorithm. To validate its performance and to show the supremacy of this method it has been further compared with conventional Perturb and Observe (P&O) and Incremental Conductance (IC) Algorithms. The simulation study has been carried out for various steady state and dynamic operating conditions. The boost converter experimental setup has been developed in the laboratory to test the feasibility of the system. dSPACE DS1103 control interface is for Real Time Implementation (RTI). The experimental results have shown very good agreement with the simulation results.
为了克服部分遮阳条件对光伏系统最大功率点跟踪的影响,采用蚁狮优化算法(ALO)设计了一种新的光伏系统最大功率点跟踪算法。在多变的大气条件下,传统的算法无法对峰值点进行跟踪。这项工作的新颖之处在于提出了蚂蚁狮子优化器(ALO)算法,该算法具有在可变大气条件下执行的能力。对ALO算法进行了详细的仿真和实验工作。为了验证该方法的性能,并进一步将其与传统的扰动和观察(P&O)和增量电导(IC)算法进行了比较。对各种稳态和动态工况进行了仿真研究。在实验室建立了升压变换器实验装置,以验证该系统的可行性。dSPACE DS1103控制接口用于实时实现(RTI)。实验结果与仿真结果吻合较好。
