EBOOK - Electrical power systems quality (Roger C. Dugan)


EBOOK - Chất lượng hệ thống điện năng (Roger C. Dugan) - 525 Trang.

Both electric utilities and end users of electric power are becoming increasingly concerned about the quality of electric power. The term power qualityhas become one of the most prolific buzzwords in the power industry since the late 1980s. It is an umbrella concept for a multitude of individual types of power system disturbances. The issues that fall under this umbrella are not necessarily new. What is new is that engineers are now attempting to deal with these issues using a system approach rather than handling them as individual problems.
