In a power system world, breaker failure protection became a critical element to provide a back up protection for circuit breakers (CBs). Practically, every apparatus is equipped with primary protection to interrupt the current flow whenever a fault occurs. Thus, the breaker failure relay opens adjacent breakers to isolate the problem. Fast and secure breaker failure detection algorithm would be a critical challenge facing a numerical BF relay. In the first part, it presents the need for breaker failure protection. The second part addresses issues worth consideration when applying Breaker Failure Protection and lastly, advances towards breaker Failure Protection. Using algorithms significantly enhance the numerical BF protection.
Contingency analysis remains to be one of the great tasks that face protection engineers. The reason to this is due to the fact that a Protection Engineer has to focus on Murphy’s Law and Ohms Law concurrently. The design for PRS plays a key role in detecting any fault that happens on the power system and the possibilities of eruption of any fault in the protection system of the power system. When the protective relay system is order, the designers of the power system understand it but the condition changes when a failure is detected. Deriving solutions towards this failure is what makes a protection engineer proficient. The protection engineer can only succeed by understanding how operations of the system. The best approach that the engineer can have is to have a proper understanding of each component of the system as well as their interaction and overlaps needed.

To successfully analyze this topic, the differences between fault detec...

Essay on Failure Prediction Algorithms

- Gaining a better understanding of when electronics are about to fail can help engineers and companies be more effective in providing reliable electronics; this will also lead to a greater return on investments for businesses (Seggie, Cavusgil, & Phelan, 2007). Prior attempts of implementing algorithms have all failed due to the large bandwidth required to process the data in real time. The algorithms in this study will not require many resources and will use simple gate-logic and statistical data to alert an end-user of a potential failure....   [tags: Technology]

Research Study- Improved Algorithms for Yield Driven Clock Skew Scheduling in the Presence of Process Variations

- Abstract Traditional yield driven clock skew scheduling in the presence of process variations can be formulated as a sequence of minimum ratio cycle problems, and hence can be solved efficiently by algorithms such as Lawler's and Howard's algorithms. However, the assumption of Gaussian distributions of critical path delays has been made in this formulation, which becomes inapplicable for next generation nanometer technologies. Recently, a generalization of the formulation for non-Gaussian distributions was proposed, and a modification of Lawler's algorithm was developed for solving this generalized problem....   [tags: algorithms]

Ethical Accounting Failure: The Enron Scandal Essay

- According to Croxford” Ethical accounting failure has continued to occur in multinational companies in spite of the increased legislation, enhanced corporate governance programs, and greater attention on business ethics by the academic community.” (Croxford, 2010) According to his research, (Croxford, 2010) believed “that accounting professional was discriminated against based on their age, culture, gender, and education.” Multinational corporations have been facing ethical failures scandals for many years....   [tags: audit, quality control, detection of fraud]

Algorithms in Engineering Control Systems Essay

- Increasing requirements for design of system with increased fault tolerance is the current trend in design of control systems. Since the majority of real control systems are non- linear, algorithms dealing with a class of non-linear systems use the approach of Takagi-Sugeno fuzzy models. These algorithms deals with fault diagnosis, reconfiguration of the system and solve problems related to the constraints of the system and the time delay that occurs in complex control systems. All real systems in nature, such as physical, biological and engineering systems, are susceptible to defects of its compo- nents....   [tags: Automation, Linear, Engineer]

Study on Trust Evaluation Algorithms of Domains in Grid Environment Essay

- In order to achieve a reasonable evaluation of direct trust, this paper proposes a trust evaluation algorithm based on the domain, using the technique of constructing a hierarchical tree of trust evaluation subjectively. The algorithm adopts the rules of series and parallel operations in the D-S theory, acquires the results of the recommended trust problem of a single path by quadrature methods and implements the integration of multiple paths by the weighted algorithm which takes the cooperative roles and industry roles as factors....   [tags: algorithm, manufacturing industry, ]

The Pathophysiology of Acute Renal Failure Essay

- Explain the pathophysiology of acute renal failure. Include prerenal intrarenal and postrenal causes. According to the Mayo Clinic Staff (2012), acute kidney renal failure occurs abruptly when your kidneys lose their filtering abilities and cannot filter waste products from your blood. This is also known as acute renal failure or acute kidney injury. When this happens, high levels of waste may become accumulated in your blood and will alter your bloods chemical make up causing them to get out of balance....   [tags: Acute Renal Failure]

Essay on Understanding Acute Renal Failure

- The pathophysiology of acute renal failure is divided in 3 different causes. Out of the 3 causes of acute renal failure pre renal is the most common. It may result in hypoperfusion and ischemia. Pre renal is caused by a sudden drop in blood pressure or renal interruption of blood flow from the kidneys from sudden severe injury or illness. Intrarenal is caused by direct damage to the kidneys either by inflammation, toxins, drugs, infection or reduced blood supply. Postrenal is a sudden obstruction of urine flow due to an enlarged prostate, kidney stones or bladder tumor or injury....   [tags: Pathophysiology of Acute Renal Failure]

Essay on The ID3 Algorithm

- The ID3 Algorithm Abstract This paper details the ID3 classification algorithm. Very simply, ID3 builds a decision tree from a fixed set of examples. The resulting tree is used to classify future samples. The example has several attributes and belongs to a class (like yes or no). The leaf nodes of the decision tree contain the class name whereas a non-leaf node is a decision node. The decision node is an attribute test with each branch (to another decision tree) being a possible value of the attribute....   [tags: Classification Algorithms]

Breaker morant Essay

- English Breaker Morant Essay topic: Statement of Intention: The most primary reason why I decided to express my views creatively upon this issue, of the film Breaker Morant by Bruce Beresford, is that the order made clear by the British High Command sent out to the Bushveldt Carbineers was bitter and simple. To fight the Boer on its terms, and to take no prisoners. Such an order could prove fatal, especially to Lieutenant Harry Breaker Morant, who was dishonorably used as a scapegoat for the British Empire to appease political conflict between Germany at the time....   [tags: essays research papers]
