Manitha P. V., ,, Sudharsan, S., Manikumaran, K., and Aswathaman, K., “Design and development of enhanced road safety mechanism using smart roads and energy optimized solar street lights”, in 2017 International Conference on Energy, Communication, Data Analytics and Soft Computing, ICECDS 2017, 2018, pp. 1650-1654.[Abstract]


Energy optimization is an important aspect in these days and it is applied in every domain. Technologies like smart street lighting and automated speed breakers are few which are applied in transportation domain. The work focus on two aspects. First one is to optimize the energy consumed by the street lights by introducing smart solar street lights. Second one is to enhance road safety and thus by optimizing the fuel consumption. To achieve the smart street lighting, a combined technology of piezo sensors and LDR sensor is proposed. The piezo sensors are used for detection of vehicle speed, which will actuate the speed breakers. The LED's are powered using batteries which are powered by a solar panel. A controller circuit is installed for the monitoring of charge in the batteries, to prevent from overcharging. The power output from the solar panel is given to the MOSFET which is used for lighting the LED. To actuate the speed breaker, a servo motor is paired with a rack and pinion, for the translation of rotatory motion to linear motion. To perform all this control functions, Arduino micro controller is used. © 2017 IEEE.

P. P. Reddy, Suresh, P. V. B., P. Reddy, T., Manitha P. V., and Dr. K. Deepa, “Remote Control of an Electronic Device Using EOG”, in International Conference on "Smart Technologies for Smart Nations(Smart Techcon 2017), Bangalore, India, 2017, pp. 780-783.[Abstract]


Over 1 billion of the world population have some form of disability which corresponds to 15% of the world population. And this disability suppresses their ability to communicate with the physical world. The proposed prototype provides an opportunity for such people to be self-reliable and enhances the ability of the disabled people to operate the electrical and electronic devices remotely, without the assistance of fellow beings. This prototype aims at providing an eminent platform for disabled people to communicate with the physical world at an equitable price. Human eye is capable of producing a corneo-retinal potential whose magnitude varies from 0.4-1mV with a frequency ranging from 0-35 Hz. This is attributed to the high metabolic rate of retina. The proposed model exploits this appealing property of human eye. It encompasses the ECG electrodes to trap this potential and is fed as an input to the amplifier circuit. Further, the amplified signal is conditioned using a signal conditioning circuit to remove the noise creeping into the signal. This is wirelessly transmitted using an RF module to the receiver circuit and from there it is used to trigger the required circuit. A LED is triggered to ensure the functionality of the framework.

I. Nagar, Rajesh M, and Manitha P. V., “A Low Cost Energy Usage Recording and Billing System for Electric Vehicle”, in International Conference on Inventive Communication and Computational Technologies (ICICCT 2017) , Coimbatore, India, 2017, pp. 382-384.[Abstract]


As conventional fuel resources are dwindling, electric vehicles are emerging as the only viable alternative to petrol, diesel and gas based vehicles. However, the biggest stumbling blocks in the proliferation of electric vehicles is the issue of conveniently charging electric vehicles. In this paper, a smart, low cost ac charging system for electric vehicles is discussed. This is accomplished by having a two-part system in which one part deals with the operation of dispensing electric energy and displaying usage and the other part looks after operations such as billing, storing usage data, customer information etc.

Conference Paper

M. Soman, Manitha P. V., and K. Ilango, “Design and control of a soft switching grid connecting inverter using PI controller”, in 2016 Biennial International Conference on Power and Energy Systems: Towards Sustainable Energy (PESTSE), 2016.[Abstract]


This paper describes control and design of a new single phase dc-ac converter with soft switching operation. This converter operates with soft switching under discontinuous mode of operation. A snubber capacitor is connected to the dc terminals of a full bridge converter configuration, because of this snubber capacitor an additional switch is required to disconnect it from the dc side. A new control approach is used for the implementation of the proposed grid connecting converter. The closed loop control is simulated using PSIM smart controller. Voltage signal which are control parameter responsible for real power exchange from the renewable energy source to grid are considered in the simulation. More »»

This paper discubes about the various custom power devices used in custom power park. The custom power plant ensures the delivery of high grade of power to customers. The performance of shunt active filter, DVR, SSTS, pabive filter and overall CPP controller are analyzed. Simulation is carried out using Matlab Simulink platform. The control algorithm used for shunt active filter and DVR are ICosO and IRPT respectively. A shunt pabive filter is designed to eliminate the lower order harmonics so that the rating of shunt active filter can be reduced considerably. The controller for SSTS is based on voltage detection scheme. The voltage of preferred and alternate feeders are sensed and given to the overall controller of custom power park.

This paper presents a control strategy for shunt active filter interface for distributed generation scheme without degrading the power quality in the grid. The control strategy used enhances the performance of shunt active filter by sharing active power being generated from distributed generation to grid as well as load in addition to regular functions such as current harmonic elimination, reactive power compensation, power factor correction. The modified control algorithm is designed and analyzed for non-linear load using MATLAB/Simulink. The simulation results shows good performance of controller for power quality improvement of distributed generation system interfaced through shunt active filter. © 2014 IEEE.

Develoving efficient interfacing technologies to interconnect renewable energy sources with grid is a promising research area in renewable energy related applications. The interfacing unit becomes crucial as renewable energy sources when directly connected to grid, can inject harmonic components that may deteriorate the quality of power. This paper proposes a mechanism to use shunt active filter as an interface between renewable energy sources and grid with a modified and efficient control scheme. The shunt active filter with this modified controller controls the real power supplied by the grid (source) in addition to its usual functions such as reactive power compensation, power factor correction and harmonic elimination. Performance of the modified Icosφ controller is compared with that of IRPT control algorithm. Two nonlinear loads are considered here namely AC voltage controller as soft starter for induction motor and a diode bridge rectifier feeding resistive load. Simulation of proposed system proves the effectiveness of using a shunt active filter as the interfacing unit for grid integrated renewable energy systems.

<p>The grid integrated renewable energy sources are becoming a common area of interest for power generation in the recent times. The design and development of efficient interfacing technologies to interconnect renewable energy sources with grid is catching a lot of attention among the researchers these days. The interfacing unit becomes crucial as renewable energy sources when directly connected to grid, can inject harmonic components that may deteriorate the quality of power. This paper proposes a mechanism to use shunt active filter as an interface between renewable energy sources and grid with a modified and efficient control scheme. The shunt active filter with this modified controller controls the real power supplied by the grid (source) in addition to its usual functions such as reactive power compensation, power factor correction and harmonic elimination. The non-linear load is diode bridge rectifier feeding resistive load and the unbalanced load also introduced to verify the controller performance. The simulation of the proposed system under both balanced and unbalanced load conditions have been done and the obtained results prove the effectiveness of using a shunt active filter as the interfacing unit for grid integrated renewable energy system.</p>
