Investigation of power quality issues and its solution for distributed power system Abstract: Power quality is the collections of the all electrical networks as the ability of the system of an equipment to function satisfactorily that type of electrical equipment permit the important manner is the without continuous loss of life of the all electrical equipment. All the electrical equipment fails that when the exhibit power quality problems.
Many problems can result from poor power quality, especially in today's complex microelectronics environment. In the past, electrical disturbances on mechanical equipment went unnoticed. Now, however, electrical disturbances can upset today's high-tech equipment operations severely. Approximately 80 percent of power quality problems originate from the customer's side of the meter. It's important for facility owners, managers, designers and other high-tech equipment users to understand and learn how to avoid power disturbances. Review the following for a general overview of power quality:. It's normal for your electric service voltage to vary within the prescribed limits.
Abstract: Recently a large interest has been focused on power quality domain due to: disturbances caused by the non-linear loads, increase in the number of electronic devices and growth of renewable energy sources. Power quality measures the efficiency of electric power transmitted from generation to the industrial, domestic and commercial consumers. In a power system voltage sags and voltage distortion introduced by harmonics are considered to be the most severe affecting power quality because of both utilities and consumers are affected by these disturbances. These problems could be solved by: design equipments and electrical systems to prevent electrical disturbances from causing equipments or systems to malfunction, analyze the symptoms of a power quality problems to determine its causes and solutions, study the medium that is transmitting the electrical disturbance and eliminate or reduce the effect of that medium, treat the symptoms of the power quality problems by using the power conditioning device and custom power device. This study, presents the power quality problems such as sags, swells, harmonics, voltage interruptions and transient and presents power quality enhancement techniques which are two categories power conditioning devices and custom power devices the second method is the most efficient and effective method to solve the power quality problems and protective the sensitive loads from power disturbances. Three phase fault and double line to ground fault are created with the proposed system and the faults are initiated at a duration of 0.

Тогда он дотронулся до его руки. - Сэр? - Беккер легонько потормошил спящего. - Простите, сэр… Человек не шевельнулся. Беккер предпринял очередную попытку: - Сэр. Старик заворочался.
Как это удобно. Вспомнив всю услышанную от шефа ложь, она похолодела и посмотрела на него, в глазах ее мелькнуло подозрение. - Это вы убили Танкадо.
Офицер подошел к столу. Кожа на левой руке загорелая, если не считать узкой светлой полоски на мизинце.
А неприятности немалые. - Ты сама видишь. Впервые за последний час она позволила себе улыбнуться. - Этих слов я и ждала от. Он пожал плечами: - Как только мы получим ключ, я проинформирую директора.
Хейл зашевелился и в ответ на каждое завывание сирены начал моргать. Неожиданно для самой себя Сьюзан схватила беретту, и Хейл, открыв глаза, увидел ее, стоящую с револьвером в руке, нацеленным ему в низ живота. - Где ключ? - потребовала. Хейл с трудом пришел в. - Ч-что произошло.
Лиланд Фонтейн, - представился он, протягивая руку. - Я рад, что вы живы-здоровы.
