“…The same footnotes are applied between inductances in Equation (4) and reactances in Figure 3, transferred from the inductances for simplification. The subtransient reactances, x d " and x q ", transient reactance, x d ', and steady state reactances, x d and x q , are calculated by the equivalent circuits, as described in Equation (5).…”

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.

“…In the literature, there are many reports of various tests and methods to estimate the transient parameters of a synchronous machine, which are represented as terminal operational impedances and time constants [5,6]. However, these studies mainly focus on a machine that has already been designed or produced.…”

“…Although the proper establishment of these formulae is beyond the scope of this paper, we briefly outline a possible way to do it: 1) obtain the losses for different values of the geometric parameters and create a database; 2) use an identification technique to set up an optimization problem, with the parameters of black-box models as the main variables (these can be preselected formulae); and 3) solve the optimization problem using stochastic or deterministic optimization methods [37]- [42].…”

This paper presents design improvements to lower the temperature in the clamping bolt (CB), in a single-phase extrahigh-voltage (EHV) shunt reactor. Laboratory temperature measurements, under overload and nominal load conditions, were performed in the middle of the two top main air gaps inside one of the slots drilled in the CB using commercial fiber-optic temperature sensors. 3-D finite-element (FE) simulations were performed to calculate fringing losses in the CB. Subsequently, the fringing losses were employed as a heat source for static-steady thermal analysis using 3-D FE simulations. Convective heat-transfer coefficients were selected with a methodology that leads to a close match between measured and simulated temperatures. Two practical design enhancements to diminish temperatures in the CB are analyzed using measured and simulated data. These alternatives improve design and reduce potential failures and, hence, increase the EHV shunt reactor lifetime. Index Terms-Clamping bolt (CB), extra high voltage (EHV),finite element (FE), magnetic lamination packages (MLP), opticalfiber temperature sensors, shunt reactor.

“…This is due to the fact that these signal generator-based test methods need specific instruments. The practical identification strategy using a VSI-fed drive without additional instruments to get accurate d-q axis inductances is important for PMSM control [10]. HF injection is an effective method to estimate inductances by analyzing the relationship between the HF voltage and the induced HF current.…”

Offline inductance identification of a permanent magnet synchronous motor (PMSM) is essential for the design of the closed-loop controller and position observer in sensorless vector controlled drives. On the base of the offline inductance identification method combining direct current (DC) offset and high frequency (HF) voltage injection which is fulfilled at standstill, this paper investigates the inverter nonlinearity effects on the inductance identification while considering harmonics in the induced HF current. The negative effects on d-q axis inductance identifications using HF signal injection are analyzed after self-learning of the inverter nonlinearity characteristics. Then, both the voltage error and the harmonic current can be described. In addition, different cases of voltage error distribution with different injection conditions are classified. The effects of inverter nonlinearities on the offline inductance identification using HF injection are validated on a 2.2 kW interior PMSM drive.
