This paper proposes a methodology for modeling the equivalent network of an inductor used in domestic cooking applications. Nowadays, the most widespread model corresponds to an RL-series equivalent; however, it excludes the frequency dependence that occurs in such systems. This paper proposes a network which considers the impedance variation with the frequency. The equivalent impedance is obtained...
An equivalent circuit method is used to define ports at the slots of enclosures to separate the external field domain from the internal over a broad frequency range. The aspect ratios of internal to external structures of electronic devices are usually difficult to handle in joint domain simulations. Our method provides the opportunity to simulate the domains separately and to connect the two models...
This paper proposes a new voltage instability risk indicator based on local phasor measurements at fast sampling rate. The effectiveness of the indicator is analyzed at EHV load and ldquotransitrdquo buses. The risk criterion is based on the real-time computation of the Thevenin equivalent impedance of the classic electrical circuit given by an equivalent generator connected to an equivalent load...
