Abstract
Disclosed is a power calculation method of a magnetic circuit. In view of the power problem of a magnetic circuit and the phase problem of a magnetomotive force (MMF) and a magnetic flux in the magnetic circuit, the present disclosure draws a magnetic circuit vector diagram based on an equivalent magnetic circuit vector model, and provides a method for calculating virtual magnetic active power, virtual magnetic reactive power, and virtual magnetic complex power of the magnetic circuit by analyzing the MMF, the magnetic flux, the reluctance, and the magnetic reactance in the magnetic circuit by using the magnetic circuit vector diagram. A mathematical relationship between the virtual magnetic power of the magnetic circuit and the electric power of the corresponding equivalent electric circuit is derived according to a conversion factor between the virtual magnetic power and the electric power, so that the electric power can be directly calculated according to magnetic parameters such as the MMF and the magnetic flux in the magnetic circuit. The power calculation method of the magnetic circuit provided in the present disclosure can calculate and analyze the virtual magnetic power of the magnetic circuit according to the magnetic circuit vectors, so as to calculate the electric power from the magnetic circuit through conversion. The electric power can be solved according to the magnetic circuit vectors directly when the electric vectors are not available to calculate electric power in electromagnetic components.
