Physical Fundamentals of the Power Theory of Electrical Systems  

Fizyczne podstawy teorii mocy obwodów elektrycznych

prof. dr hab. inż. Leszek S. CZARNECKI

Abstract

Delivery of the electric energy from its producers to customers is described in terms of powers, defned in a frame of power theories of electrical systems. Currently there are several of such theories, however. All of them are mathematically correct but differ as to the interpretation of the physical phenomena which accompany the energy transfer and affect its effectiveness. These phenomena are discussed in this paper. Explanation and credible interpretation of the physical phenomena that accompany the energy transfer is crucially important for the right defnition of the electrical powers and methods of compensation.

Streszczenie

Dostawa enegii od jej producentów do odbiorców jest opisywana za pomocą różnych mocy elektrycz-nych, defniowanych w ramach teorii mocy obwodów elektrycznych. Niestety, istnieje obecnie kilka takich teorii. Wszystkie one są matematycznie poprawne, mogą się jednak zasadniczo różnić co do interpretacji zjawisk towarzyszących przesyłowi energii oraz ich wpływowi na skuteczność tego przesyłu. Zjawiska te i ich interpretacje są właśnie przedmiotem tego artykułu. Wyjaśnienie i poprawna interpretacja zjawisk fzycznych
związanych z przesyłem energii elektrycznej jest krytycznie ważna dla poprawnego defniowania mocy elektrycznych i metod kompensacji.
