“…Therefore, defining reactive power as the sum of its values on every harmonic is useless, carrying no information. Multiple publications stated the same [1,2]. The method provided below is good for metering and paying for electric power, with higher harmonics presented in the main lines.…”

“…A review of the existing investigations has shown that there are currently no scientific publications on this issue. Some exceptions are articles [26][27][28][29], which, using elements of the electromagnetic field theory, make a physical explanation for the occurrence of reactive power Q and distortion power D in electrical circuits with nonsinusoidal voltages and currents. They mostly use the well-known expression of the Umov-Poynting theorem in its complex form to express the balance of powers over volume V of the periodic electromagnetic field, and conclude that the real part of this expression describes active power P and the imaginary part describes reactive power Q.…”

Electrodynamics of Reactive Power in the Space of Inter-Substation Zones of AC Electrified Railway Line

In railway traction, the definition of “electromagnetic field” is functionally connected to the concept of the reactive power consumed by the electric rolling stock, and characterized by the running and standing electromagnetic waves in the space of the inter-substation zones from the site of the AC traction system. Such a definition is established and theoretically justified by the theory of electromagnetic fields. This article uses the methodology of this theory, in particular, a method for power balance estimation in electromagnetic fields based on Maxwell’s equations, as well as methods for the analysis of running and standing electromagnetic waves based on the theory of reflection, propagation and transmission of plane harmonic waves. The research considers the regularities of standing electromagnetic waves in the space of inter-substation zones of electric traction systems, which occur due to the incomplete reflection of incident waves from the contact wire and metal parts of the roof surface and the frontal part of the body of the electric rolling stock. The flow of electricity to the roof surface and the frontal part of the body of an electric locomotive is considered. The possibility of using existing methods to reduce wave reflections and thereby to effectively compensate for reactive power in the space of inter-substation zones is discussed.
