Additional digital layer is an important aspect in the Smart grid architecture. We gather the data using this layer and the whole grid is controlled accordingly. Energy cost can be estimated and the demand can be predicted. Estimation of health issues of electrical equipment can be done from the control room by gathering the data from remote locations. In the case of computer-aided digital relay model if we choose the pilot relay action by remote data then that would be the good application of this digital layer. In this paper, we have suggested an alternative method- to gather and analyze the remote data using the serverless cloud computing framework. The prime objective is to design a cheaper and technically easier simulation strategy with this new framework. At the end, we have tried to create a mathematical model to estimate the cost and quality of service. The system is simulated using MATLAB, Amazon Web Service (AWS) products and a batch program.

Bidirectional flow of power in power network imposes a serious threat on the reliable operation of overcurrent relays. Coordination of overcurrent relays is a challenging problem in multi-feed and heavily meshed power network. Complexity of problem increases as the size of system increases. Recently artificial intelligence based optimization techniques are applied successfully for optimizing the relay settings. Traditionally overcurrent relays are electro-mechanical in nature with discrete time dial and plug setting. Optimization of relay coordination problem considering electro-mechanical based over current relays requires an optimization algorithm which can handle the discrete types of variables. In this paper application of CMA-ES optimization algorithm is extended for coordination of overcurrent relays. Relay coordination problem is modified to optimize the relay setting for both near and far end faults. In addition to minimization of total operating time of primary and backup relays, coordination time margin is also optimized between 0.3 to 1.0 second for reliable operation of backup relays. The performance of proposed CMA-ES optimization algorithm is compared with other well established artificial intelligence bases optimization algorithms

Current Limiting Reactors (CLR) connected in series with the transmission line, limit system short circuit currents on occurrence of a fault. Cost and size of these current limiting reactors is conventionally attributed to the system specified peak short circuit current and the inductance, as peak short circuit current and the duration of short circuit are the basis for size of the conductor. The conventional designs overlook the fact that peak current flowing through CLR is not constant but changes with the instant of short circuit. The short circuit currents also differ substantially from one short circuit to other. This variation in peak short circuit current, spread over from minimum to maximum, is statistically studied and generalized using PSCAD simulation in this work, for a standard power system (40kA) to study the scatter, highest amplitude and frequency of occurrence. Number of experiments has been conducted utilizing randomly selected short circuit events and for various sample sizes. Authors have co-related results and defined optimal experiments for acceptable prediction accuracy. The work is extended further to develop an empirical relation defining the change. The authors claim that substantial reduction in cost and size of CLR is possible considering statistical rating of CLRs against conventional.

A single-phase, single-stage current source inverter (CSI) suitable for transformer-less grid-PV interface is proposed in this paper. A split capacitor arrangement and a common mode choke are used to modify the conventional CSI structure, to reduce the leakage current. Higher reliability and voltage boosting capability of the CSI are the main advantages compared to the voltage source inverter (VSI). A cost effective and computationally less intensive control method based on the sinusoidal pulse width modulation (SPWM) technique is suggested to improve the quality of the grid current. Design and analysis of the proposed CSI structure and the modified control technique is discussed in detail. Reduced leakage current and high quality injected grid current, with a relatively low value of inductor is obtained with the suggested modification. Simulation results validate the effectiveness of the proposed CSI with the proposed modification in the SPWM technique.

In the modern world, almost 90 percent of the motors used in the industry are induction motors. Induction motors are used in wide range of applications ranging from fans, pumps, compressors to their use in complex drives for critical application. As the world advances, newer applications come up which require robustness and complete operational control over an induction motor, when subjected to most adverse dynamic real time conditions. These applications need to be controlled using control techniques such as Field Oriented Control, which require the knowledge of induction motor. Use of sensors adds to the cost. If the machine parameters are known, it is possible to eliminate the use such costly hardware speed sensors and replace them with software speed estimators. Scope of this paper is design, simulation and implementation of speed estimation algorithm by estimating the rotor flux angle and slip in a Digital Signal Processor(DSP). The rotor flux angle and estimated speed can be used in sensor-less rotor field oriented control scheme. First, a code is developed for speed estimation of induction motor and is tested in MATLAB. Later, this code is ported to TMS320F28335 floating point DSP and is tested on a 415V, 3.3 HP 1430 RPM squirrel cage induction motor to estimate its speed in real-time.
在现代世界，工业中使用的电机几乎90%是感应电机。感应电机的应用范围很广，从风扇、泵、压缩机到关键应用的复杂驱动器。随着世界的进步，新的应用出现了，当受到最不利的动态实时条件时，需要对感应电机进行鲁棒性和完全的操作控制。这些应用需要使用控制技术进行控制，如磁场定向控制，这需要感应电机的知识。传感器的使用增加了成本。如果机器参数是已知的，就有可能消除使用这种昂贵的硬件速度传感器，并用软件速度估计器代替它们。本文的研究范围是在数字信号处理器(DSP)中通过估计转子磁链角和转差率来实现转速估计算法的设计、仿真和实现。转子磁链角和估计转速可用于无传感器转子定向控制方案。首先，编写了异步电动机转速估计代码，并在MATLAB中进行了测试。随后，将此代码移植到TMS320F28335浮点DSP上，并在一台415V, 3.3 HP 1430 RPM的鼠笼式异步电动机上进行测试，实时估算其转速。

In an acoustic partial discharge (PD) detection system, estimation of time difference of arrival (TDOA) between acoustic signals arriving at a sensor array is an important criterion for accurate localization of PD sources inside a transformer. The localization accuracy can be improved by improving the accuracy of estimation of TDOA between sensors. The estimation of TDOA is a challenging task because acoustic signals are corrupted by noise, reverberation, echo and reflection of acoustic signals inside the transformer tank. Keeping this in mind, this paper presents a technique for the accurate estimation of TDOA by extraction of an estimate of the PD pulse from the recorded acoustic signals. The TDOA between two sensors is then calculated by finding the cross-correlation function between the two sensors. The acoustic path through the transformer tank and oil constitutes the physical system, which when excited by the PD pulse, gives rise to the acoustic pressure waves. An estimate of the PD pulse, which generates the acoustic pressure waves, may therefore be obtained by separating the acoustic response of the tank-oil physical system from the acoustic signal. The extracted PD pulse information gives an estimate of the instant of appearance of the PD pulse at each sensor, which makes the accurate estimation of TDOA possible.

Indian distribution sector is constantly facing energy crises. With the increasing dependency on electrical and electronics appliances the demand of power is rapidly increasing. Extensive work is going on to increase the generation capacity by encouraging renewable energy integration for generation diversification, energy conservation and regulations, development of open access energy markets etc. but simultaneously it is also important to optimally use the existing generation capacity. Electricity theft and meter tampering is one of the most important causes of increasing gap in demand and supply and poor financial condition of distribution sector in the country. Unaccounted energy due to theft is a barrier in the growth of Indian economy. With the advancements in metering technologies different new ideas of illegal electricity theft are also being introduced by consumers. This scenario is very challenging for the profitable operation of distribution sector and putting them in loss. In this paper we have discussed meter tampering and theft issues and their drawbacks. Smart meter can work as the best solution to control theft events due of its features of remote data communication and connect /disconnect ability.

The objective of this paper is to control the speed of a non-linear D.C. servo motor using various control techniques. Installing only a Proportional controller (P) to control the system, it is observed that there is high overshoot (OS), undershoot (US) and the system takes time to achieve its steady state. The performance of the system relatively improves by installing a conventional PID controller as it decreases the overshoot, undershoot of the system and the system attains steady state faster. The conventional PID controller cannot tackle the nonlinear systems effectively and gives a poor tracking and disturbance rejection performance. In order to further improve the response of the system, Improved Self Tuning Fuzzy (ISTF)-PID controller has been used. In this technique fuzzy logic is used to tune the gains of a PID controller. The various control techniques that are discussed in this paper are designed to achieve the desired D.C. servo motor speed.
