Government of Nepal has agreed with India on energy banking with aim to enhance the energy security of respective national grids. The general concept of this banking is that the surplus energy available in Nepal during the wet months is absorbed by the power system of India and Nepal will retrieve the much needed banked energy during dry months. Ho...

Currently, wind power is the fastest-growing means of electricity generation in the world. To obtain the maximum efficiency from the wind energy conversion system, it is important that the control strategy design is carried out in the best possible way. In fact, besides regulating the frequency and output voltage of the electrical signal, these str...

This volume is aimed at contributing to the comprehensive assessment of the socio-economic impact of COVID-19. Experts have voluntarily crafted it based on their experiences and input from diverse stakeholders. Our main objective is to help prevent Nepalis from becoming destitute in the immediate run and to help them bounce back in the medium run.

The fact that electricity consumption is undeniably related to the growth of a nation also incorporates the growing need of electricity which also brings power theft like issues. Further the ability to effectively generate electricity by power generation bodies’ gets halt when in the process of distribution, energy theft occurs. And with the advent...

Lightning Arresters (LAs) are widely used in electrical distribution system for the protection of various electrical equipments of distribution sub-station. For the protection of those sub-station equipments including sub-station transformer, the insulation coordination study is performed which determines the voltage level of electrical equipments...

p>Accepting the benefits of automation and to avoid the existing issues in semi-automated entrance examination system, Institute of Engineering (IOE) had decided to move into fully automated computer based entrance examination system in 2013. IOE had implemented automatic answer sheet scanning and processing system since 2004 and started online bas...

A tool of efficiency and convenience, Wireless Power Transmission (WPT) has a great potential to improve the quality of life of people. A wireless power system basically consists of a transmitter and receiver devices in which the transmitter generates an oscillating, time-varying electromagnetic field. This paper presents a novel approach for WPT u...

Wireless Power Transfer (WPT) has a great potential to improve the quality of life of people with downside being low efficiency of the system. This requires special attention in design and optimization of the system. This paper presents a novel approach for WPT using class E inverter. The wireless power system setup with transmitter and receiver we...

This paper presents analysis of impact of synchronous machine based distributed generation (DG) in distribution networks at various penetration levels. Higher DG penetration level raises important issues about distribution system operation. Therefore, new techniques are needed to determine the maximum amount of DG that may be installed without requ...

This paper describes an algorithm used for the load flow analysis of distribution system with distributed generation (DG). A simple model is proposed to carry out the load flow analysis of the radial distribution system including the distributed generation connected to the buses modeled as PV(constant active power and voltage magnitude) buses and n...

This paper discusses cost of unreliability of electricity supply to the residential customers. Electricity supply outage cost is evaluated by customers' survey technique for urban and semi-urban residential areas of a developing country. The energy consumption pattern of urban and sub-urban areas is determined. Electricity supply outage cost is eva...

The electric utilities in the developing countries lack sufficient data required for long-term electricity supply system planning which have resulted in wide gap between demand and supply in these countries. Also, there is lack of coordination among different constituents of electric utilities generation, transmission and distribution. Vital data f...

This paper has investigated the nonuniform characteristics of a counterpoise based on the frequency-dependence of R, L, C, and G and propagation parameters identified from measured results of transient voltages and currents on the counterpoise. It becomes clear that the characteristic impedance is significantly length-dependent (i.e non-uniform, at...

This paper investigates frequency-dependent parameters of a counterpoise which are identified from measured voltages and currents by a numerical optimization technique. Based on the investigation, the frequency characteristics of the impedance and the admittance are made clear. Then, Sunde's formulas of the frequency-dependent impedance and admitta...

A methodology has been developed for accurate distributed-parameter modelling of a transient on a buried bare conductor based on measured results. The developed bare conductor model including its frequency-dependent effect is implemented into the EMTP so that a transient simulation on a power system can be carried out by the EMTP. The EMTP simulati...
