This paper presents a novel impedance-based approach for out-of-step (OOS) protection of a synchronous generator. The most popular and commonly used approaches for detecting OOS conditions are based on the measurement of positive sequence impedance at relay location. However, FACTS devices change the measured impedance value and thus disrupt the performance of impedance-based relay function. In...

Accurate computing of the saturated inductances of Permanent Magnet Synchronous Machine (PMSM) is very important during the design process. In this paper, a new method is presented based on the B-H characteristic of the stator material and unsaturated inductances formulations. This method is used to calculate the saturated inductances of the axial flux PMSM. The synchronous inductance and all o...

The purpose of this work is to take an arbitrary 2phase synchronous circuit and eliminate its global clock while preserving its externally visible behavior. This is done by converting it into a set of self-timed combinational circuits with latches and a clock generation network that uses only a local handshake. We discuss the overhead required by this approach to selftiming and outline opportun...

Conventional delay-insensitive (DI) data encodings require 2N+1 wires for transferring N-bit. To reduce complexity and power dissipation of wires in designing a large scaled chip, a DI data transfer mechanism based on current-mode multiple valued logic (CMMVL), where N-bit data transfer can be performed with only N+1 wires, is proposed. The effectiveness of the proposed data transfer mechanism ...

AbstructThe specification of a synchronous circuit can be given as a set of abstract building blocks that are interconnected. A set of fast algorithms are presented here for the selection of components that map each of these abstract building blocks to one of a number of suitable physical components. The first set of algorithms select the set of fastest or cheapest (smallest area) of all possib...
