“…The resistances of the stator and field windings can be accurately calculated by using an analytical solution from design data and are set in the winding components in the external circuit. The end leakage inductance of the stator and field windings (L se and L fe in Figure 5), damper cage end ring equivalent resistance, and end leakage inductance of the adjacent bars (R c , L c , R ic , L ic ) are also obtained analytically [12,14]. The external circuit parameters are summarized in Table 2.…”

“…Magnetic vector potential (MVP) methods have been used to calculate the inductance parameters [13].

“…This phenomenon should also be considered in the computational analysis of leakage inductance and finally in the determination of transient parameters. FE computation of leakage inductances has been previously reported and discussed in [14][15][16][17][18][19].

This paper presents a novel method for calculating the transient parameters of a saturated salient-pole synchronous machine (SPSM) with damper cage using finite element analysis. All detailed leakage inductances in a modified d-q model are discussed and separately extracted. In addition; the frozen permeability method is used in a 2-D finite element analysis to consider saturation and skin effects for determining the inductances. The terminal reactance parameters are obtained from all elements of the d-and q-axis equivalent circuits in all the chosen time constants during the transient process. The variation of leakage inductances of the SPSM in transient processes is also investigated and discussed. To determine transient time constant parameters; the Prony algorithm is applied in the presented method. A program developed to automatically solve the simulation and computation with the proposed method is described. This method is applied to a prototype and validated by experimental results. Some discussion about the relationship between rotor geometric design and the transient parameters of SPSMs is provided. The variation of leakage magnetic field of SPSMs in transient processes is also investigated. This method can be applied in transient parameter estimation and optimization of SPSMs in the design stage.

A quasi-static approach based on lumped equivalent circuits is presented and investigated for an efficient numerical analysis of miniature RF circuits. In this approach, the static capacitances and inductances including mutual capacitances and inductances of individual circuit components are first evaluated using the finite element method. An equivalent lumped circuit based on the calculated capacitances and inductances is then constructed for the entire circuit, whose analysis predicts the frequency responses of the circuit. The accuracy of this quasi-static approach is investigated by comparing its solution with that of the full-wave analysis based on Maxwell's equations. It is found that the quasi-static analysis is very accurate for a miniature RF circuit whose electrical size is smaller than a fraction of the effective wavelength.

The starting performance of a large tubular submersible induction motor is affected by welding slots. To accurately calculate the starting performance of the double bar entirely tubular submersible induction motor (DBETSIM), an equivalent circuit diagram of DBETSIM is established, and the calculation formula of the starting torque of the motor under is derived. Then, the finite element analysis method and the equivalent circuit parameter method were used to calculate the starting parameters, respectively. Comparing DBETSIM with the normal tubular submersible motor, it is found that the second bar structure can improve the starting performance of the motor. Finally, the structure and material of the second bar are optimized and analyzed. It is concluded that the starting performance is improved most when the welding material is aluminum alloy with narrow and deep welding slots, which provides a reference for the design and optimization of DBETSIM. © 2019 Institute of Electrical Engineers of Japan.
