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.

    An ANN based approach for assessment and improvement in voltage stability of power systems
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2007-02) Negi, Geeta; Swami, A.K.
    Use of new technologies and the growth in interconnections are continuously increasing the complexity of the system. These highly complex modern power systems are operating in severely stressed conditions due to economical and environmental considerations rendering them venerable to frequent failures. Voltage stability has become a major concern as the present system is operating near its maximum capacity level. To get information regarding voltage stability margin and its improvement, various methods has been used in past. This work deals with L-index and VCPI techniques to calculate the stability margin and give information about the weak areas of the network. By using L-index the settings of control strategies can be known and by making proper changes in these values the operator of ECC can avoid the unwanted situations. ANN is an intelligent tool with parallel computational capability. It can perform nonlinear mapping in short duration. Once neural network is trained, it provides acceptable recommendations in a short time, which is suitable for online application. Here ANN is used to predict the values of L-index, VCPI, and control Quantities (generator excitation and settings of SVCs), which become helpful to the operator for handling the unfavorable conditions. These methods are applied on IEEE-9 bus and IEEE-14 bus system. An attempt is made to find best results that the voltage stability margin can be assessed and improved.

    Performance analysis of axially laminated anisotropic synchronous reluctance motor
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2005-07) Rawat, Harendra Singh; Banerjee, G.K.
    In an effort to obtain better performance of SRM by obtaining a high ratio of direct (d) axis to quadrature (q) axis magnetizing inductances ( d q L L ) an axially laminated anisotropic (ALA) rotor was designed and fabricated. To construct an ALA rotor the axially laminated segments were constructed with multiple C.R.G.O laminations interleaved with milo paper insulation sheets. The thickness of C.R.G.O lamination and milo paper insulation sheet were of .2 and .25 mm respectively. The rotor has been designed for four poles configuration. The objective of this study was to design and fabricate axially laminated anisotropic synchronous reluctance motor for performance analysis. Parameters of SRM determined by A.C stand still test. The saturation effect was studied by synchronous running test. We analyzed the steady state and dynamic state behaviour of the SRM by developing a mathematical model. The presence of third and fifth harmonic at no-load and load condition was also determined. The results reveal that the steady state analysis performance on simulated of SRM as well as experimentally on test motor were in close agreement. The saturation effect was found negligible in motoring mode. The harmonic contents included third and fifth harmonics in very small percentage and increased slightly with loading.

    Study of shunt active filter for the harmonic current compensation of nonlinear load using PQ theory
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-07) Pandey, Deepak; Goel, S.K.
    Due to the intensive use of power converters and other non-linear loads in industry and by consumers in general, it can be observed an increasing deterioration of the power systems voltage and current waveforms. The presence of harmonics in the power lines results in greater power losses in distribution, interference problems in communication systems and, sometimes, in operation failures of electronic equipments, which are more and more sensitive since they include microelectronic control systems, which work with very low energy levels. Because of these problems, the issue of the power quality delivered to the end consumers is, more than ever, an object of great concern. International standards concerning electrical power quality impose that electrical equipments and facilities should not produce harmonic contents greater than specified values, and also specify distortion limits to the supply voltage. Meanwhile, it is mandatory to solve the harmonic problems caused by those equipments already installed. Passive filters have been used as a solution to solve harmonic current problems, but they present several disadvantages, namely: they only filter the frequencies they were previously tuned for their operation cannot be limited to a certain load; resonances can occur because of the interaction between the passive filters and other loads, with unpredictable results. To cope with these disadvantages, recent efforts have been concentrated in the development of active filters. This thesis present the analysis of Shunt Active Filter for harmonic current compensation based on instantaneous active and reactive power theory through MATLAB/Simulink tool.

    Design and feasibility analysis of 30 KW GCPV and wind-solar hybrid system
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-07) Naveen Kumar; Goel, S.K.
    With the increasing energy demand and target of climate pledge to cut down the carbon emissions of its GDP by 33 to 35 percent by 2030 from 2005 levels has forced India to move with renewable sources of power generation. As solar and wind are the most promising sources of renewable energy but geographically solar is feasible at almost every place in India. There is an issue with solar power that it is available only with emergence of sun. Wind-solar hybrid is a better option as the reliability of system is higher than any of the single component. This is necessary to find out the overall comparison of these two types of grid connected plant before installation. So this has given the idea of technical and financial analysis of both types of plants at different geographical location. GCPV plant is designed with the help of PV*SOL simulator while the output of hybrid system is analyzed in MS excel. Result shows that small GCPV is commercially feasible at all selected geographical location. Further, hybrid system has higher reliability and can be installed at where power cut is unavoidable, but at higher capital and operating cost.
