“…It is possible to see that the starting electro-mechanical torque for the saturated conditions has a lower magnitude than the one for the saturated one. Furthermore, the torque frequency and phase are not affected by the saturation validating previous results in saturation modeling [16], [17], [26], [27].…”

Real time simulation plays a fundamental role in the design and validation of hardware and software for power electronic converters and electric drives. In this paper, an FPGA based real time platform for simulation of power converters and electric machines is presented. Strategies for modeling power electronic devices are explained and compared. In addition, a Thevenin based equivalent model of a switch is enhanced to model the on characteristics of these devices. This motivates the design of an electro-thermal algorithm for FPGA implementation. With respect to electric machines, different methods for modeling of the saturation characteristics are evaluated for their use in real time simulation. A procedure to efficiently compute the saturation characteristics is proposed. Lastly, a Hardware in the Loop (HIL) model of an Electric Vehicle (EV) drive is used to illustrate the machine saturation.Index Terms-Ac-dc power converters, dc-dc power converters, electric machines, ac machines, vehicle dynamics, electrothermal effects 0093-9994 (c)

“…One of the most influential factors which influences the dynamic and steady state response of a machine is saturation. Although this topic has been studied extensively for offline simulations [16], [17], it is considerably new in its implementation for real time simulation.…”

“…In many cases, the generator modeling includes field winding together with the control system to evaluate time domain performance (Barakat et al, 2011). However, to calculate the frequency response, the synchronous generator inductance, stable armature ground capacitances and the balanced operation of the generator are particularly important (Barakat et al, 2011, Despalatovic et al, 2011, Hadi and Wijaya, 2013. Figure 2 shows the circuit corresponding to the modeling of the generator:…”

The structure of the induced voltage test model for low frequency transients is described and presented from its components (generator, auxiliary and power transformer). The performed test procedures are perfomed to estimate the model parameters along with the topology of their connection. Finally, the model is implemented in the transient analysis software ATP and a frequency response of the test is obtained. This allows to identify the critical frequencies that cause resonant states and cause overvoltage during the test which facilitates the establishment of application of safety criteria for both operators and the equipment.

“…Generators can be modeled in several ways [23][24]; in this research work they are modeled by means of sinusoidal voltage sources behind impedances with a fundamental frequency of 60 Hz and 1.41 per unit peak amplitude; the transmission lines are modeled with an equivalent pi model, and the electrical linear loads can be modeled in different ways [7]; in this work they are represented by a parallel R-XL network.…”

The harmonic state estimation analysis has been conventionally developed in the frequency domain. This methodology needs to measure the amplitude and phase angle of the harmonic components of the related waveforms. This paper presents an alternative time domain formulation based on a simplified network model and Kalman filter to assess the global harmonic steady state estimation. Measurements are sampled waveforms registered by a data acquisition system. The proposed methodology has been successfully tested on an experimental electric power test system developed in the laboratory. The reported case study consists of a three phase balanced system with a nonlinear load. An under-determined measurement model case has been tested. The results have been validated by direct comparison of the state estimation response against the actual data taken from laboratory experimental measurements and have also been compared against the simulated values obtained from Simulink®.
