Sai Shibu N. B., Satish, A., D, A., and Rao, S., “Automatic Antenna Reorientation System for Affordable Marine Internet Service”, in IEEE International Conference on Computational Intelligence and Computing Research (ICCIC), At Madurai, 2018.[Abstract]


Fishermen are completely isolated from the sea shore while they are fishing in the ocean. They travel more than 120 km into the ocean for fishing. Mobile phone coverage exists only till 15 km from the shore. In such scenario, passing information like bad weather alerts to them is nearly impossible. Due to which hundreds of fisherman could lose their lives in the ocean. 'OceanNet' is an affordable solution developed to solve this problem in communication. The system comprises ad-hoc infrastructure networks that uses long-range Wi-Fi solution and enables offshore connectivity for fishing boats. The long range CPE deployed in the boats used directional antennas. As the boat moves, the orientation of this directional antenna changes leading to loss of connectivity. In this paper, we propose a solution to solve this problem by developing an automated antenna reorientation system that maintains the alignment between the CPE and the base station and ensures good connectivity. We also discuss on the outcome of this developed solution that solve the problem with the antenna alignment.

OceanNet project uses a hierarchical point-to-multi-point backhaul network using long range Wi-Fi technology to provide extended offshore connectivity for fishing vessels. This work is aimed to understand the interrelationship between the design parameters and the reason for considering specific parameter values for the OceanNet solution. The research work explores the communication systems theoretical limits on received power with respect to the variation due to transmitted power, distance, antenna type, frequency, and modulation schemes. These different models that explain the interrelationship are simulated to gain deeper understanding to the design of communication systems. This paper discusses the variation in received power and transmitted power with respect to change in distance for a given frequency, comparison of channel bandwidth with channel capacity, analysis of signal to noise ratio and its impact on different modulation schemes. We also analyse different antenna types used for the deployment and how the performance is affected due to congestion in the nodes. This paper also details the results and analysis of the simulation performed based on fishing vessel scenario

C., Mohan, V., and , “Elevating Education of India's Rural Village Girls Through Distance Learning Technology Supported by Sustainable Electricity”, in GHTC 2017 - IEEE Global Humanitarian Technology Conference, Proceedings, 2017.[Abstract]


Augmenting educational opportunities for rural village girls in India has been highlighted as a significant Millennium Development Goal (MDG) necessary to help eradicate poverty in developing countries. The role of proper electrification in rural villages, another MDG, plays a significant role in providing necessary energy for educational needs. In a small village in the state of Jharkhand, India there are serious problems with current limited educational opportunities, particularly for girls, as well as electrification problems. These obstacles were assessed, and it was determined that with a proper and reliable electrification system in place, a Distance Learning (DL) educational program to support village education could support continued and constant education for girls through primary and secondary school. Interviews with villagers resulted in very positive support for such a system within the village. In this paper we address the current obstacles to education in the village. Also presented are the practical challenges in attaining the technical framework for the proposed DL innovation including software, suitable learning facilities, network connectivity, personnel support, and so on, all dependent upon a larger framework of reliable sustainable power system. In terms of electric availability, it is widely assumed that Indian villages now have electricity through efforts of government initiatives. However, the reality is that in many villages the actual electrical access has not been adequate to meet even simple village needs. A sustainable electrification model to support current grid is also currently underway for the village. The overall goal of the program is to enhance academic educational achievements of village girls, adolescents, and adults, thus helping to uplift the standard of living in the village, and diminishing current problems related to current low educational status of most there.

Mohan, and Manoj P., “Assessing Village Power Grid Problems for Development of Quality and Stable Supplemental Sustainable Energy”, in 2017 IEEE Global Humanitarian Technology Conference (GHTC), 2017.[Abstract]


The UN Millennium Development Goals have in recent years understood and emphasized the critical connection between rural poverty and health issues, and lack of any or proper electrification. Although Indian village electrification has been a priority for the government for a number of years, it is a huge task given the millions of households residing in rural areas. Further, not all claims of village electrification reflect actual access to the grid nor consistent quality of access, when available. This paper addresses an assessment of electrification challenges in villages, as well as potential renewable resource availability. In response to electrification concerns expressed by villagers in the state of Jharkhand, a functional assessment of the existing grid was conducted, as well as an assessment of personal, business, and community electrification needs expressed by villagers. Multiple problems were discovered and are reported here. With village participation, alternative sustainable energy sources were explored, and the most feasible alternative sources to meet village needs for sustainable, reliable energy supplementing the current grid were identified. This paper also presents a detailed needs-assessment of villagers which will influence the potential sustainable energy solution.

Internet of Things (IoT) is an emerging technology paradigm that can be incorporated in various applications such as Smart Grid, Smart Home, and Communication Networks etc. Wireless Sensor Networks (WSN) are playing a key role in various applications such as landslide detection, waste management, water quality monitoring in rivers and lakes etc. One of the most data critical applications of WSN is Smart grids. The major problem in the existing power grid is the lack of reliability as one cannot predict power failure. The primary cause of power failure is the energy scarcity and the lack of awareness among the users of the energy availability and their usage limits. This result in increase in the energy consumption costs and projects the impression that electricity is unaffordable in the user's mind. Smart Grid offers promising solutions in transforming the existing power grids into a reliable and cost efficient grid by using WSN. This paper focuses on incorporating IoT into Smart Grid and then various security challenges faced therein. It also introduces a solar energy harvester for Smart City Framework, a community of buildings, each equipped with a solar energy harvesting system, which can share their energy according to the decision taken by the control station. There by, it proposes a cost-effective Smart Grid model using distributed renewable energy generators that helps meet the local power demands.

Rural development is one of the major focus in developing countries like India, since more than 70% of citizens live in rural village. Studies show that inequality in Energy access, often hindering the collective development initiatives in those villages. This paper describes the electrification project carried out in the village of Komalikudi, Idukki District, Kerala, India where 60 % of households were not connected to state power grid. As part of this study a detailed analysis of economic levels of the community and the requirements on education, healthcare, skill development, social business etc., has been developed. Based on these requirements, a feasibility study has been performed for different renewable energy options available in the locality. The study results based on resource availability, access to the area of deployment, availability of skilled workers, Energy awareness, and commitment are used to design a 5KW hydro based generation and distribution system which energy equality and subsequently community development. A pilot deployment has been operational and reciprocating this novel innovative model to other 101 villages is ongoing with Amrita Vishwa Vidyapeetham. © 2016 IEEE.

Sai Shibu N. B. and Dr. Balamurugan S., “Design of Active Series Compensator for Real Power Flow Rerouting in Transmission System”, IEEE International conference on Power and Energy Systems: Towards sustainable Energy PESTSE - 2016. IEEE, Department of Electrical and Electronics Engineering, Amrita School of Engineering, Bengaluru , p. 91, 2016.[Abstract]


In this paper, the real power flow control in a transmission line is done by using active series compensation technique. The active compensator varies the power angle in the line using a power electronic device. The power angle is varied by injecting voltage to the line that is in phase shift with line voltage. This varies the real power flow in transmission line. Using this technique, the rerouting of power flow can be achieved to satisfy the inequality constraints. By controlling the injected voltage magnitude and the phase angle, accurate power flow control can be achieved. In this paper, an embedded system based active series compensator is developed and the power flow control in a two bus system is achieved effectively.
