The study of electrical machines is a classic subject in electrical engineering and usually involves the understanding of transformers and rotating devices. Several simulation programs can give a good platform to help the electrical engineer to find a reasonable solution with quite accurate loading predictions and minimum costs. This chapter gives the foundations of this subject that might be very important for students, engineers, and designers to work through a model based on a simulation design approach. There are two simple ways of simulating an induction machine (IM) in PSIM: either using an equivalent circuit PSIM block made up with electrical components or using the premade equivalent block that can be embedded in the electrical circuit simulation. Some types of rotating loads demand for a good speed control. In laboratory tests, it is very common to use a DC motor driving a loaded self‐excited induction generator (SEIG) to keep constant its load frequency.
This chapter first introduces the induction machine, starting with a physical analysis. This is followed by an explanation of the commonly used single-phase steady-state model of induction machines. A very simple and effective mathematical model is presented that allows the electrical and mechanical quantities of the machine to be quantitatively evaluated at the various speeds. As regards induction-motor drives, the chapter presents a simulation using a more detailed model. A method for determining the parameters of the equivalent circuit of an induction machine consists of two tests: the no-load test and the blocked-rotor test; these tests are discussed in the chapter. The chapter shows how to operate the inverter in order to obtain a good performance in variable-speed operation from the machine. Finally, the chapter examines single-phase induction motors to know what the most common household AC machines look like inside and to determine how they work.
In the rotor of an inverter-fed induction machine, a considerable power-loss may occur, which is caused by the pulsed output voltages of the inverter. This loss can reach unexpectedly high values and in the worst case it may lead to the destruction of the machine. The major part of that loss is caused by the harmonics of the stator currents, which are compensated by corresponding currents in the rotor's squirrel cage. Unfortunately, field diffusion effects lead to a very inhomogeneous distribution of current density across the rotor bars. Hence, there will appear high peak values of current density in the rotor bars and, in consequence, a considerable and unexpectedly high power loss. The following paper shows a method for analyzing the distribution of current density across the rotor bars and determining the resulting additional rotor loss, that has to be expected. By this way, the machine itself as well as the inverter and its pulse pattern can be optimized in order to reduce this power-loss.<<ETX>>
The effects of unbalanced supply conditions on the performance of two aerospace induction machines are examined. Two analytical techniques are employed namely 2D finite element analysis modified for end-effects and a conventional equivalent circuit analysis. In this latter method the supply voltages are resolved using symmetrical components theory into positive and negative sequence sets which are applied to appropriate equivalent circuits. The conclusions reached are that for the sample machines (approximately 4.2 kW and 64 kW), the effects of unbalanced conditions at the general aerospace industry limits are tolerable as far as current balance, torque reduction and heating are concerned. The torque ripple, however, increases significantly, which could be a concern
Most industry experts agree that the next generation of commercial drives will include some sort of sensorless torque control. Achieving a modest level of control in the very low-speed range in fact greatly increases the competitive value of the drive and expands its range of applications. After reviewing many of the previously presented sensorless control methods, this paper shows that the simple method of stator flux orientation can provide zero speed torque control equally as well as more complex approaches which rely on elaborate mathematical models to improve the operating range. This paper experimentally demonstrates that by using only a slight amount of low-pass filtering in the integration of the stator voltage, a reasonable flux estimate can be obtained for stator flux field oriented torque control. With this simple method adequate torque control can be achieved even at zero rotor speed.
Summary form only given. The IEEE First and Second Benchmark models for Sub- Synchronous Resonance (SSR) are used to analyze the damping properties of an induction machine damping unit (IMDU) coupled to the shaft of a turbo- generator set. This paper investigates the rating and location of the induction machine that, without the aid of any controllers, effectively damps subsynchronous resonance for all line series compensation levels. Eigenvalue analyses are performed on linearized models of the shaft system including the induction machine to find the optimum location. The best location of the IMDU, providing maximum damping, is next to the HP turbine at the end of the shaft. Time domain simulations are conducted to find the adequate rating of the induction machine. It is observed that a small size, high power (about 10% of the generator rating), low energy machine effectively damps SSR. The IMDU reduces peak torques in shaft sections during transients. In the paper, it is demonstrated that the addition of an IMDU at the end of the shaft would have prevented the SSR events of the Mohave Desert shafts.
In the following investigation the modeling and control strategy of a doubly fed induction machine is discussed for power production/electric propulsion purposes, when being incorporated as a shaft generator into a ship's system. When the doubly fed induction machine serves as a power production machine, contributes to lower emission of CO2 and fuel saving. This is due to the fact that the doubly fed induction machine is capable of working at different speed (lower) than synchronous. This coincide with the enforcement with which the International Maritime Organization (IMO) and the EU demand reduction of Ship's emissions. The system of the doubly fed induction machine is being controlled by implementing a practical form of a vector control technique which has been previous developed in the case of the control of variable speed wind energy systems. The electrical torque of the double fed induction machine is regulated to be constant and the doubly fed induction machine is allowed to perform within the range of zero to the twice of the synchronous speed. The relevant results demonstrate a very good regulation of the speed at various operational points either as in the motor or the generator mode.
