Available in PDF, EPUB and Kindle. Book excerpt: When an induction generator is connected to a utility line supply, the voltage and frequency at the terminal output are the same as the voltage and frequency of the utility line supply to which the generator is connected. The reactive power needed by the induction generator is supplied by the utility and the real power is returned to the utility. With a fixed frequency dictated by the utility, the induction machine starts generating above the synchronous speed. The range of speed is also limited by the slip. At a very high slip, the copper losses increases as the current increases. On the other hand, in an isolated operation, the induction generator operates in self-excitation mode. It determines its own voltage and frequency. These two quantities depend on the size of the AC capacitor, the induction machine parameters, the electrical load, and the speed of the generator. The operating speed of the induction generator is extended without generating excessive loss. This paper presents an analytical study by utilizing a circle diagram to illustrate the operation of the induction generator in isolated operation. The steady-state calculations are presented to support the analysis. Possible applications for the system in variable-speed generation are currently under investigation. The output can be directly connected to equipment that is non-sensitive to the frequency (a heater, battery charger, etc.) or can be connected to a converter to get a fixed-frequency AC output.

Book Synopsis ELECTRICAL MACHINES by : M. RAMAMOORTY
Download or read book ELECTRICAL MACHINES written by M. RAMAMOORTY and published by PHI Learning Pvt. Ltd.. This book was released on 2017-11-01 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers a brief history of electricity, fundamentals of electrostatic and electromagnetic fields, torque generation, magnetic circuits and detailed performance analysis of transformers and rotating machines. It also discusses the concept of generalised machine which can emulate the dynamic and steady state performance of DC and AC machines. To serve the specific applications of drive systems in industries, many new types of motors are developed in the last few decades. A separate chapter on ‘Special Machines’ is included in this book so that the students should be made aware of these new developments. The book covers the syllabi of many universities in India for a course in Electrical Machines. Therefore, this book would serve the needs of the undergraduate students of Electrical Engineering.
