Essays on Transmission Line

Electrical power in New Zealand is generated majorly from renewable energy sources such as wind, geothermal and hydropower. Renewable energy sources contribute 75% of the total power generated in the country. As a result, New Zealand has one of the greenest energy infrastructures in the world. Energy demand in the country has been steadily rising by an annual margin of 2.1% from 1974 to 2010. However, energy demand fell by a margin of 1.2% in the period spanning from 2010 to 2013. New Zealand is above average in global energy intensity ratings. However, it has also been ranked among ...

Implications of Erecting Additional Transmission Lines

Introduction Auckland is one of the regions in New Zealand. Auckland does not have many power generation sites like the other regions in New Zealand. However, the demand characteristics for Auckland are still high and are projected to increase due to population growth and economic development. Given that many of the energy production sites have been developed and the development of the remaining sites faces opposition from environmental groups, the viable options for easing the supply issues in Auckland include the development of renewable energy sources such as wind and solar energy, the optimization of the current transmission network ...

Introduction

Over time, the growth of a city of a locality leads to the increase in the demand for electricity. The growth in population and the commercial activity puts pressure on the national grid. Without commensurate investments in the generation of power, the increase in demand results in shortages. To supplement the shortage of electricity in the region, more power can be brought in from the generation sources. However, this is complicated if the power generation plants are located far away. This is because more high voltage overhead transmission lines would be required. The Ministry for the Environment (2010) finds ...

Electrical Engineering is a field of engineering concerned with the design, maintenance and study of everything related to electricity, including electrical energy, systems and devices. This discipline comprises the different electrical phenomenon in all its application forms, as well as the problems derived from its use. Specifically, Electrical Engineering studies the generation, transmission and distribution of electrical energy, as well as its applications through analog and digital electronics, control and automation areas, instrumentation, communication systems, among others subfields. Electrical Engineers have a wide field of work, as they are responsible for the development of new electrical equipment, solving electricity-related ...

Electric power transmission is the transfer of bulk quantities of electrical energy. This electrical power is transmitted from the generating electrical power plants to the electrical substations that are located in the proximity of the demand centres. The wiring that is performed between the elevated voltage substations and the clients is described as electric power distribution. The transmitting lines that are connected are transformed into the electrical energy transmission networks. The combination of the electrical energy distribution and the electrical energy transmission is acknowledged as the power grid. The term is similar in the United States and the United ...

Implications of Transmission Lines and Grid Network of New Zealand

Abstract This report aims to evaluate implications of transmission line and existing mechanism of transmission distribution network in New Zealand. There are various theoretical and real life implications posed by transmission lines including environmental and health issues, security system, problems associated with voltage and so forth. Quality material and mechanized system can minimize these implications. Un-organized transmission lines effects ecosystems that are essential for sustainable atmosphere and environment. Moreover , transmission lines arrangement within the ground leads to other issues ...

The faults are analyzed in different methods. The software tools have been employed to analyze the faults. It has been assumed that all the electric motors are in phase and operating at a nominal voltage. This load usually supply power to the transmission line rather than drawing power from the transmission line. The fault may be occurred by the motor loads. The following calculations are necessary to find the faults. - Subtrnsient Fault Analysis - Trasmit arises between sub transient and the steady state - The steady state arises, when the transient have the time to settle ...

Article Summary and Analysis: A Mal-Trip in the Peruvian Power System

Article Summary and Analysis: A Mal-Trip in the Peruvian Power System Distance transmission line protection is important in the modern environment where extra high transmissions are commonplace. Distance relays are vital in securing these transmissions. Much consideration is required when designing and installing transmission line protection systems to avoid possible mishaps similar to the case of Peru by Jacome and Henville (2001). This paper presents a summary and an analysis of this case.

In his informative and educative article, Jacome and Henville (2001) observed that distance delays are vital in transmission line protection and may be set on the ...

In today's world of increasing energy needs and environmental concern establish our focus towards more alternatives to use non-renewable energy sources. One of such alternative can be solar energy. Solar energy simply is the energy produced by sun and can be collected elsewhere. Sun creates its own energy by a thermonuclear way that make a conversation of about 650,000,000 tons of gas hydrogen into helium per second. This process creates electromagnetic, heat and radiation.

Innovation is the process of is bringing socially together the skills and knowledge of different persons to generate a new knowledge or skills. These best skills can brought together by hiring best researchers with specific experience and training . If we look at the pre-industrial economy, In limited technological education and knowledge, this combining of best skills has to occur through personal contacts, it show that effectiveness of individual's as an innovator of technology will be dependent on the skill of his social network persons. First we need to understand technology ethics and process involve in saving solar energy through solar ...
