three-phase system it should be split into a positive sequence component, a negative sequence component and a zero sequence component.
Normally, the voltages produced are perfectly balanced because of the characteristics of the synchronous generator. Also, the effect of some geometrical asymmetries in the delivery electric system could be neglected. So, it is possible to state that unbalanced loads drawing unbalanced currents can be considered as the main cause of unbalanced voltages.
3. Conclusions
In this article, an overview of the main disturbances affecting the electrical power system operation has been presented. Harmonic issues have been investigated more deeply. Additionally, monitoring and evaluating the power quality from the point of view of harmonic disturbances have been introduced. The necessity to have a standard method to identify the sources of electrical power quality deterioration, and to evaluate accurately the actual proportion of responsibility of each of the players involved has been underlined.
4. My research
My name is Prokhorov Anatoly. I have graduated Norilsk Institute of Industry in 2001, on a speciality "Electric drives and automation of technological processes and manufactures ". Now I the post-graduate student. The theme of my scientific work: "Parameters of quality of the electric power and electromagnetic compatibility of equipment "is very interesting and fast developing part of a modern science. My head of studies - Alexey Gennadevich Karpov. He's very competent scientist and uses often non-standard approaches in the decision of trivial problems. I am very glad that I have possibility to co-operate with such interesting person. The essence of my scientific work consists in definition of power supply parameters, making the greatest impact on non-failure operation of mechanisms of the enterprise. Are not rare cases when two and more mechanisms, feeding from one transformer, disturb to normal job each other. Because of generation hindrances in an electrical supply network. My work is to find out what hindrances the most dangerous, and to develop methods and recommendations for struggle against them.
Введення
Останнім часом проблеми якості електроенергії привернули увагу багатьох дослідників, виробників електроенергії та її споживачів. Проблема контролю якості електроенергії ставати все вагомішою внаслідок широкого використання несиметричних і поперемінних однофазних і трифазних навантажень і це все більш і більш зачіпає мережі електропередачі в приватних, комерційних і промислових секторах. Погіршення якості електроенергії відбувається як через збурень викликаних перехідними процесами (кидки і осідання напруги, імпульсні перешкоди) так і в сталих режимах (гармонійні спотворення, несиметричність, флікер). Основні причини таких спотворень, так само як і що надаються ними негативні наслідки добре в...
