This paper discusses feasibility of conventional and fully static reactive power compensation techniques used in the solution of power quality problems of coal conveyor belt drives and also describes the features and field performance of the Distribution type Static Synchronous Compensator (D-STATCOM) prototypes in such applications. They are composed of 2-level, 3-leg Voltage/Current Source Converters (VSC/CSC), low-pass input filters and Delta / Y connected coupling transformers to allow their connection to medium voltage load bus. Reactive power is controlled in both capacitive and inductive regions by phase-shift-angle control. Dominant voltage/current harmonics of VSC/CSC are eliminated by Selective Harmonic Elimination Method (SHEM). Developed D-STATCOMs are shown to comply with IEEE Std 519-1992 even for the weakest supply. Viability of D-STATCOM in reactive power compensation of conveyor belts has been proven in the field.

Implementation of a vector controlled induction motor drive
Acar, Akın; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2004)
High dynamic performance, which is obtained from dc motors, became achievable from induction motors with the recent advances in power semiconductors, digital signal processors and development in control techniques. By using field oriented control, torque and flux of the induction motors can be controlled independently as in dc motors. The control performance of field oriented induction motor drive greatly depends on the correct stator flux estimation. In this thesis voltage model is used for the flux estima...
Vector Magnetic Characteristic Analysis of Induction Motor considering Effect of Harmonic Component due to Secondary Slot
Enokizono, Masato; Kunihiro, Naoki (2011-09-10)
This paper presents load characteristics of a three-phase induction motor model core calculated with the finite element method considering two-dimensional vector magnetic properties. Influence of harmonic components due to the secondary slot of the rotor core on the total iron loss is investigated. In this paper we propose a new iron loss calculation method to consider higher harmonic components.
High-frequency loss calculation in a smooth rotor induction motor using FEM
Ertan, Hulusi Bülent; Leblebicioğlu, Mehmet Kemal (2007-09-01)
In this paper, a new approach for the calculation of high-frequency losses in induction motors is presented. The input to the motors is assumed to be supplied from a sinusoidal voltage source. The method is based on the two-dimensional (2-D)). field solutions of the magnetic circuit, obtained by using a nonlinear "harmonic" solution. Hence, the solution time is very short. From the "harmonic" solution, the air-gap field distribution as well as the fundamental frequency eddy current losses are determined. Th...
Effects of Interruption in Power Supply of Induction Motors in Isolated Electrical Grid
Mirosevic, Marija; Maljkovic, Zlatko; Gasparac, Ivan (2011-09-10)
The aim of this paper is to analyse effects of power supply interruption on dynamics of induction motors connected to a synchronous generator in an autonomous operation. A complex mathematical model has been developed, whose components are: a diesel engine, a synchronous generator, a mechanical connection, and two unregulated induction motors which are fed directly from the synchronous generator terminals.

Benchabane, F.; Titaouine, A.; Bennis, O.; Guettaf, A.; Yahia, K.; Taibi, D. (2011-09-10)
In this paper, we present the voltage build up process and the terminal voltage control of an isolated wind powered induction generator driven by a variable speed wind turbine using rotor flux oriented vector control. A description of the studied system is provided, and a simulation study is presented. The model used for the autonomous induction generator is a diphase one obtained by application of the Park transform. Theis model permits, when adopting some simplifying hypotheses, taking account the saturat...
