Usage of Solar Photovoltaic (PV) power is increasing day-by-day because of various advantages. Government of India and all other state governments are encouraging to install the PV panels in domestic, industrial, offices and public places. However, all the installed PV panels are not effectively utilized because of lack of monitoring system. Hence, this project aims to develop a Smart Monitoring Unit (SMU) which can increase the power generation from solar PV panel and also provide continuous information about the generated power, peak power, efficiency, and shutdowns of the PV module etc.
Awards (if any)Registered and incubated a start-up at SRIX in the name of MDPSR PV Solutions.

The automobile engines which are being used now has low efficiency, more pollution, requires more maintenance and are difficult to control. So in order to overcome all these drawbacks we decided to design an engine which is eco-friendly, easy control, used in wide range applications like submarines, aerospace technology and to generate electrical energy in remote areas. In this electrical piston we are going to replace the internal combustion engine piston and bore with magnetic coil and permanent magnet set. Electro magnet is placed over the piston and permanent is attached to the piston. AC current is supplied to the electro magnet which changes the magnetic polarities for every half cycle, the permanent magnet doesn’t change its polarities. Due to the attraction and repulsion of these magnetic forces the piston moves.

In power system transmission and distribution, transformers plays crucial role. As per the consumer requirement the transformers either step up or step down voltages and deliver the power. Sometimes they are operating under overload conditions. For the Real time monitoring and protection, a hardware protection module has been designed to sense the temperature raise and pressure in the transformer tank and winding using micro controller based sensors.
In this protection flow sensor, temperature sensor, fans, buzzer and relay are connected to the microcontroller (ESP-32). The flow sensor is placed between main transformer tank and conservator tank and temperature sensor is placed in the transformer tank.
When the temperature of the transformer oil is greater than a certain temperature due to over load and weather condition, it is sensed by the temperature sensor and the signal is send to the microcontroller and based on the temperature, one or two fans are switched ON. If the temperature rises further and it is greater than pre-specified value the relay disconnect the loads.
Similarly, when the fault occurs in transformer, the oil flow from main tank to conservator tank. This oil flow signal is sent to microcontroller using flow sensor. The fault section will be isolated by the relay operation. If the relay is malfunctioned at the fault conditions, buzzer will give an indication. All this data is provided online using cloud chip.The monitoring can avoid various faults in the transformer and it can give better performance. This protection is useful for all types of transformers.

The automated irrigation system has an important role in controlling the use of electricity and water to ensure the quality of grainand to Improve Irrigation efficiency. An irrigation system typically includes a reservoir or water channel sand a pumping system. An automated system should include water level sensors an electronic controller and a supervisory system for monitoring and establishing set points. In this application water level sensors are used to sense the water level in the fields they are, continuously monitor the water in fields and gives the information to the monitoring section based on that received information pumps will automatically ON and OFF. If water level is very less in fields pumps will ON otherwise OFF. Here we are usingar89s52 micro-controller for controlling purpose and RF technology for wireless communication.

In a real-time network, the engineer must be able to apply the most simplified and efficient possible method to determine the voltages and currents at various stages of the network. To analyze and design any electrical equipment practically, one needs to develop its equivalent model mathematically. Thus for an engineering student, who is anticipating to work in the core domain of both electrical engineering and electronic engineering, Electrical circuit/Network analysis course is the fundamental key to understand, analyze and excel in their core areas. In addition, circuit/network concepts are also the fundamental keys to understand most of the Electrical and Electronic subjects.
Further, to gain expertise in the classroom learned theoretical concepts, practical sessions are significant. This course intends to develop problem-solving skills and understanding of circuit theory through the application of techniques and principles of electrical circuit analysis to common circuit problems. This laboratory practice helps students to gather hands-on experience in circuit design and development on breadboard and determination of output (V, I and power response), and validate the theoretical concepts.
