Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    Power quality is one of the main issues in today's electrical distribution system because of the escalation in use of power electronic devices. Harmonics, voltage sag, voltage swell, power interruptions, and other problems with power quality have an impact on utility distribution networks and sensitive industrial loads. In this thesis, a three-phase DVR (Dynamic Voltage Restorer) model is developed in Matlab-Simulink to protect critical loads from voltage-related power quality problems. The detailed design of the primary system parameters, including the voltage source converter (VSC), the three-phase series injection transformer, the ripple filter (Rr, Cr), and the interfacing inductance (LT) is provided. The simulation of Synchronous Reference Frame Theory (SRFT), Instantaneous Reactive Power Theory (IRPT), Affine Projection (AP), and Affine Projection Like (APL-II) algorithm based three-phase DVR is performed and analysed under a number of source side voltage quality issues, including balanced voltage sag and swell, unbalanced voltage sag and swell, and voltage harmonic distortion. The voltage harmonic distortion is analysed for both lower and higher order harmonics. PI (Proportional Integral) controller is used to keep the DC-link voltage constant. The SPWM (Sinusoidal Pulse Width Modulation) technique is used to generate gate pulses for the VSC (Voltage Source Converter) of DVR. The comparison of stability, time response, convergence speed, and THD (Total Harmonic Distortion) for both lower and higher order harmonics is done thoroughly. These control algorithms use energy-minimized voltage compensation technique which makes the Dynamic Voltage Restorer self-supporting in nature i.e. only the capacitor is adequate at the DC-bus of the VSC, and no additional energy storage device is required.
