Advanced Metering Infrastructure (AMI) is an active area of research for real-time load monitoring, dynamic pricing of power and for regulation of peak loading to minimize the stress on the electric grid caused by irregular loading patterns. Thus, AMI promises to fulfill key requirements essential for the realization of smart grids. This paper proposes a metering unit for monitoring and controlling load on the distribution side for peak load management in real time and addresses a few of the design considerations necessary for such a metering infrastructure. Further, data collected from the proposed automated metering system are processed to generate patterns of loading such that dynamic pricing schemes can be applied. In this work an embedded controller is used for the hardware realization of the metering unit and ZigBee wireless communication protocol is used for building the network that connects these distributed meters to the control tower that acts as the base station of the network. It is the aim of this work that such a metering unit will provide a practical design that is easy to implement and the proposed data processing technique can be instrumental in the formulation of versatile dynamic pricing policies.

Under the worst case scenarios, of operating environmental conditions and device parameter drift, how the performance of the circuit varies is studied. It is carried out as a part of design as to demonstrate that the circuit performs within specification. This analysis considers variation in constituent device parameters and the imposed environment, during entire lifetime.

This paper presents a 22 nm CMOS technology analog front-end (AFE) for biomedical applications. The circuit is designed for low power and small size implementations, especially for battery-powered implantable devices, and is capable of reading out biomedical signals in the range of 0.01 Hz to 300 Hz in frequency, while rejecting power-line frequency of 50/60Hz. It employs Operational Transconductance Amplifiers (OTAs) in an OTA-C structure to realize a notch filter. The OTA designed has a very low transconductance, which is programmable from 1.069 nA/V to 2.114 nA/V. The notch at power-line frequency (50/60 Hz) achieves an attenuation of 20 dB. The power consumption of the entire AFE was found to be 11.34 nW at ±0.95V supply.

The precise coordination of Directional Overcurrent Relays (DOCRs) is required to identify fault timely, effectively and isolate them from the network to avoid possible outages in a power system. The DOCRs coordination is an optimization problem including highly nonlinear constraints. In this paper, Cuckoo Search Algorithm (CSA) is implemented to solve coordination problem of DOCRs on two different case studies. The parameters of CSA are effectively tuned to obtain global best solution for the DOCRs coordination problem. The obtained results using the proposed method are compared with Genetic Algorithm (GA) and hybrid GA-Nonlinear programming (GA-NLP) methods. The result shows that the effective modification of CSA parameters can obtain feasible and superior solution for this complex problem.

With the scope of electronics increasing day by day, the need for utilizing these advanced technologies to make human lives simpler is becoming more and more necessary. The demand for using these technologies to make lives easier for disabled people is also increasing. This has prompted many new areas of research and one of the areas is electronic mobility aid for blind people. According to the World Health Organization, approximately 285 million people of all ages are blind, which is significantly a large number [1]. Traditional mobility aids include the white stick and the guide dogs which take a lot of time getting used to. There are a few smart systems available in the market which uses electronic sensors mounted on the cane but those systems also have certain disadvantages. This paper analyses the available solutions and proposes an entire new approach to solve the above problem. The new approach not only eliminates the disadvantages of the existing solutions, but it also is reliable, cost effective and most importantly easier to use.
随着电子产品的使用范围日益扩大,利用这些先进技术使人类生活更简单的需求变得越来越有必要。使用这些技术使残疾人的生活更加便利的需求也在增加。这催生了许多新的研究领域,其中一个领域就是盲人电子助行器。根据世界卫生组织的数据,大约有2.85亿各个年龄段的人是盲人,这是一个非常大的数字[1]。传统的助行工具包括白棒和导盲犬,这需要花很多时间来适应。市场上有一些智能系统使用安装在手杖上的电子传感器,但这些系统也有一定的缺点。本文分析了现有的解决方案,提出了一种全新的方法来解决上述问题。这种新方法不仅消除了现有解决方案的缺点,而且可靠、经济,最重要的是更容易使用。

In this paper, camera gimbal control is designed which controls the on board camera position used in UAV for various applications such as target tracking, Surveillance, Aerial photography, autonomous navigation and so on. Traditional tracking systems are heavy and large to mount on small airframes. Gimbal with camera replaces traditional tracking systems and used to capture aerial photography without video noise and vibrations. So, the gimbal trajectory planning and its motion control are necessary. The controlling of camera gimbal is designed using different controlling techniques which respond quickly without excitation of damping flexibility. In order to develop the control, kinematics is derived using different robotics techniques. In this paper PID controller is designed to control camera position using gimbal mechanism. PID control is the popular controller used in industries for its effectiveness, simplicity of design and its feasibility. PID consists of three tuning parameters which can be tuned using different techniques. Manual tuning is not preferred since it is time consuming, tedious and leads to poor performance. Here, traditional tuning methods and evolutionary algorithms/bio-inspired algorithms are used to tune PID parameters. PSO is the evolutionary algorithm used because of its stable convergence, dynamic and static performance, good computational efficiency due to which system performance with minimum errors can be achieved. In this paper, performance of system with conventional PID and PSO tuned PID are compared and optimum solution is implemented.
本文设计了相机云台控制系统,控制无人机机载摄像机的位置,用于目标跟踪、监视、航空摄影、自主导航等多种应用。传统的跟踪系统笨重,难以安装在小型机身上。带相机的万向架取代了传统的跟踪系统,用于捕捉航空摄影,没有视频噪音和振动。因此,对框架进行轨迹规划和运动控制是十分必要的。采用不同的控制技术对相机云台进行控制,使其在不受阻尼柔度激励的情况下快速响应。为了实现控制,利用不同的机器人技术推导了运动学。本文设计了PID控制器,利用云台机构控制摄像机的位置。PID控制以其效率高、设计简单、可行性强等优点,成为目前工业上广泛应用的控制器。PID由三个可调参数组成,可以使用不同的技术进行调优。不建议使用手动调优,因为它既耗时又乏味,还会导致性能下降。本文采用传统的整定方法和进化算法/仿生算法对PID参数进行整定。粒子群算法具有稳定的收敛性、动静态性能和良好的计算效率,可以实现最小误差的系统性能,是一种常用的进化算法。本文比较了传统PID和PSO自整定PID的系统性能,并给出了最优解。

In developing countries there are a large number of isolated areas not connected to the main grid. The energy demands of these remote, isolated communities are met by diesel operated power systems. These systems are often highly polluting and with time, an effort is made to make a transition to systems wherein single or multiple renewable energy sources are used to augment the diesel generators and thereby reduce the environmental footprint. Majority of such off-grid hybrid systems include a massive battery bank to store excess energy to supply the user when the renewable is inefficient. Inclusion of such large batteries results in additional investment costs and recycling issues. Therefore it is necessary to minimise the battery size as far as possible, and operate the system under a strategy to ensure maximum utilisation of renewable supplies and minimal DG usage. In this paper the power management strategy for a PV-battery and VSDG system was developed. A battery was modelled in MATLAB and four different battery operation algorithms were simulated for a set of data comprising of load and solar power output for every ten minute period for a day and the effective usage of DG was compared and analysed.
在发展中国家,有大量的孤立地区没有连接到主电网。这些偏远、孤立的社区的能源需求由柴油供电系统来满足。这些系统通常是高度污染的,随着时间的推移,人们努力向系统过渡,其中使用单一或多种可再生能源来增加柴油发电机,从而减少环境足迹。大多数这样的离网混合系统包括一个巨大的电池组,用于存储多余的能量,以便在可再生能源效率低下时为用户提供电力。包含如此大的电池会导致额外的投资成本和回收问题。因此,有必要尽可能减小电池尺寸,并在确保最大限度地利用可再生能源和最小的DG使用的策略下运行系统。本文研究了一种光伏电池和VSDG系统的电源管理策略。在MATLAB中对某蓄电池进行了建模,并以一天中每10分钟的负荷和太阳能输出为数据,对蓄电池的4种不同运行算法进行了仿真,对比分析了DG的有效利用率。

Comparison of efficiencies of in situ induction motor in unbalanced field conditions 不平衡磁场条件下原位感应电动机效率的比较

There has been a tremendous pressure to assess the in situ efficiency of Induction Machine (IM) with bounded level of intrusion and restricted measurements so as to enhance IMs enforcement. Very few researchers have carried out work to make IM efficiency evaluation methods compatible to unbalanced supply and varying load conditions. This paper recommends a novel approach using cuckoo algorithm to obtain efficiency assessment of an IM operating as a motor working with unbalanced supply having different phase voltages and different currents respectively. The cuckoo algorithm improves the searching ability and has competence to accommodate to complex optimization obstacles. Here, cuckoo algorithm optimizes the IM positive sequence parameters at various loading levels. The parameters optimization is done with the use of positive sequence input currents and electrical powers which have been obtained earlier at various load points of operation. Using the optimized parameters, the evaluation of negative sequence parameters can be made. So, the efficiency of IM can be estimated at different loading levels. Comparison of efficiencies at varying load points with unbalanced power supplies is carried out. The proposed approach is materialized on the MATLAB/SIMULINK platform.

在有限侵入水平和受限测量条件下,评估感应电机的原位效率,以加强感应电机的执行,已成为一个巨大的压力。很少有研究人员开展工作,使IM效率评估方法与不平衡供应和变负荷条件相适应。本文提出了一种新的方法,利用布谷鸟算法来评估在不同相电压和不同电流的不平衡电源下,IM作为电动机运行时的效率。布谷鸟算法提高了搜索能力,具有适应复杂优化障碍的能力。其中,布谷鸟算法对不同加载水平下的IM正序列参数进行了优化。参数优化是利用在运行的各个负载点上已获得的正序输入电流和电功率来完成的。利用优化后的参数,可以对负序参数进行评价。因此,可以估计不同负载水平下IM的效率。在不同负载点与不平衡电源的效率比较进行了。该方法在MATLAB/SIMULINK平台上实现。通过与遗传算法的比较,验证了所提策略的有效性、有效性和准确性。

Main objective of this paper is to develop an intelligent and efficient Maximum Power Point Tracking (MPPT) technique. Two most recently introduced and popular swarm intelligent based algorithms: Firefly algorithm (FA) and Artificial Bee Colony (ABC) has been used in this study to develop a novel technique to track the Maximum Power Point (MPP) of a solar cell module. The performances of two algorithms in this context have been compared with other popular evolutionary computing techniques like PSO, DE and GA. Simulations were done in MATLAB/SIMULINK environment and simulation results show that proposed approach can obtain MPP to a good precision under different solar irradiance and environmental temperatures.
