    (AIKTC, 2020-05) Hule, Shraddha; Ansari, Rushan Ahmed (17DEE40); Chaudhary, Ishtiyaque(17DEE43); Mapari, Maroof (15EE27); Wadkar, Muhammed Kaif(16EE36)
    The focus areas of this thesis in our group is on various aspects of Electrical, Electronics and Information technology in Home automation system (HAS) with low cost and wireless systems. Application of artificial intelligence techniques for recognition of various developments. The switch mode is used to control the home appliances. The main control system implements wireless technology to provide remote access even from a smart phone. The design remains as the existing switches are with more safety control with low voltage activating method. Presently, conventional wall switches located in different parts of the house makes it difficult for the elderly or physically handicapped people to do so. Remote control home automation system provides more modern solution with smart phones. In order to achieve this, a Bluetooth module is interfaced to the Arduino board at the receiver end while on the transmitter end, a GUI application on the cell phone sends ON/OFF commands to the receiver where loads are connected. By touching the specified location on the GUI, the loads can be turned ON/OFF remotely through this technology. The loads are operated through the Arduino board through opto-isolators and thyristors using triacs.

    Home automation using WiFi and android
    (AIKTC, 2017-05) Hule, Shraddha; Suryawanshi, Mahesh (13EE59); Yadav, Prashant (13EE62); Ghadge, Rahul (13EE39)
    The main aim of the project is to control home applications remotely by using Android-OS-based smart phone. This is an advanced technology in the home automation. Usually conventional wall switches are located in different corners of a house and, thus necessitate the need of manual operations like pressing to turn the loads on or off. It becomes very difficult for the elderly or physically handicapped people to operate them. Thus, the proposed system is enhanced to control home applications through an Android-based application of smart phones or tables that offers the provision for entering the selected numbers for operating the corresponding load. This proposed system works with an 8051 microcontroller and a rectified power supply. A Bluetooth is interfaced to the microcontroller using Rx and Tx pins for communication. Once an owner connects an Android application device to this system through a Bluetooth, then the owner can send the control signals through the Bluetooth. The owner can also enter the selected option on the Android application through the GUI for corresponding loads, and the data is sent to the microcontroller. The received data is compared with the stored data in the microcontroller and, if it matches, then the microcontroller performs the corresponding operation for controlling loads.

    Renewable energy based interleaved boost converter
    (AIKTC, 2018-05) Hule, Shraddha
    Nowadays, there is a demand to increase the power generation capacity because of steadily rising electrical energy consumption. In order to achieve this, renewable energy sources are the best option. Among all the renewable energy sources, solar power generation system tops the list. For increasing the output of these sources we need a suitable boost converter. Interleaved boost converter (IBC) is one of such converter which consists of several identical boost converters connected in parallel and controlled by interleaved method, which has same switching frequency and phase shift. The advantages of using IBC over conventional boost converter are increased efficiency, improved reliability, reduced current peak value and these converter cells have good current sharing characteristics. The proposed method provides the increased output voltage along with efficiency. Here, in this work we have also shown the application of IBC in running BLDC motor. To detect the position of BLDC motor hall sensors are used. The proposed strategies have been verified with the help of MATLAB/SIMULINK along with the hardware implementation.

    (AIKTC, 2017-05) Hule, Shraddha; Malik, Qamruddin (12EE28); Salam, Abdul (12EE43); Allauddin, Mohd. (12EE32); Malik, Aftab (12EE27)
    In India, agriculture is one of the influential sectors which affects the masses and has direct consequences towards the growth of our country. Farmers in our country, have to go through a lot of hardships to meet the demands of high yield. Conventional ways of watering have led to loss of soil nutrient, leaching, under/over irrigation, severely affecting the crop yield. Further, due to numerous issues such as resource management, changes in environmental conditions, etc., a need for efficiently managed Agriculture Control system is created. Thence, to address these issues, through this endeavor we present a design for automated setup which operates on GSM network and hence can be remotely controlled. To implement this, information is collected from the field through sensors and the inputs of the controller. To save the effort of the farmer just to check electricity status a status check feature is also added. The design provides a user friendly and reliable system which automatically intimates the user if any change of soil moisture transpires. Lastly, an attempt is made to streamline the system to in an economical way.

    Smart energy meter
    (AIKTC, 2018-05) Hule, Shraddha; Khan, Yusuf J. (15DEE23); Deshmukh, Mohammad (15DEE11); Shaikh, Faisal K (14EE36); Shaikh, Itban (14EE38)
    It is a difficult job for the electricity board officials to manually take meter readings and calculate bill as it is time consuming and requires man power. Billing consumers for energy consumption is not uniform. It is a tedious job for the electricity board official to manually go and take meter readings of big industrialists and reset their maximum demand after recording it. Even the latest energy meter is not tamper proof. Hence considering all these factors it is possible to design an energy meter that is tamper proof, supports automatic metering and billing system. Also at the same time helps in finding the energy theft in transmission lines. Considering all these features that can be done by a single energy meter it is called a SMART ENERGY METER. The smart energy meter will be an electronic device that will record consumption of electric energy and communicate the data collected to the electricity supplier for monitoring and billing. It typically records energy hourly or more frequently. The gathered statistics is then transmitted to the supplier and corresponding billing calculation is done. Communications from the meter to the network may be wireless, or via fixed wired connections such as power line carrier (PLC). Our project uses embedded GSM technology to transmit the data from meter to the service provider.

    Speed control of three phase induction motor using two level vector control
    (AIKTC, 2019-05) Hule, Shraddha; Siddiqui, Shabbir Ahmed (16DEE84); Mahfuz, Alam (16DEE62); Khan, Hussain I. Pathan (16DEE67); Shaikh, Mohammed Tahir (14EE40)
    The main objective of this project is to introduce the non-conventional approach of speed control of ac induction machine that is vector control or field oriented control of induction motor. The advantages of vector control and need of vector control is explained, also the need of field oriented control of induction motor is mentioned and the various methods of FOC is illustrated. The project entitled “Speed Control of Three Phase Induction Motor Using Two Level Vector Control” is conducted at control and instrumentation division of one of the premier research institute of India Bhabha Atomic Research Centre, Trombay, Mumbai where we implemented the dynamic modelling of three phase induction motor and two level space vector pulse width modulation is also implemented on matlab Simulink along with the detailed study of field oriented control of three phase induction motor. Induction motor or asynchronous motor is the most extensively used in the industrial, commercial, residential settings as these motors are simple and robust in construction having low cost and minimum maintenance, high dependability and sufficiently high proficiency due to these conveniences ACIM are most widely used in industrial applications. However, control of ACIM is more difficult than the control of DC machines, with the help of scalar methods speed can be control as it is simple to implement but it has the coupling effect thus it is responsible for slow response which leads to oscillations due to higher order effect. But in many operations and machinery in industries sensitive revolutions and torque adjustment have to be peripheral with high accuracy, so dc motor drives were generally used variable speed drives because of the simplicity of control due to decoupling between armature current and the field current. This study has been undertaken to investigate the speed control ACIM using field oriented control. The principle of vector control of electric drives is based on the control of both the magnitude and the phase of each phase current and voltage. for this purpose, the study of available conventional and non-conventional approaches has been presented. This report also presents a clear study which illustrates introduction of efficient vector control of ACIM.
