In this paper, we present a novel and effective fault detection diagnosis (FDD) method for wind energy converter (WEC) system with nominal power of 15 KW, which is designed to significantly reduce the complexity computation time possibly increase accuracy diagnosis. This strategy involves three significant steps: first, size reduction procedure applied training dataset, uses hierarchical K-mean...

Abstract. This paper presents a fault detection and isolation algorithm applied to the monitoring of DC Motor parameters. Fault Detection and Isolation (FDI) schemes are implemented as real-time algorithms whose inputs are plant output observations. They are basically used for a) fault detection: to decide whether the plant is in a normal operating condition or in a faulty one and b) fault isol...

This paper describes a new design for a fault tolerant Hbridge dc-dc converter. Open circuit and short circuit fault tolerance is achieved using multilevel converter topology in combination with pulse width modulation control strategy allowing a large set of converter switching states to produce bidirectional power flows at any required output voltage. If two switches fail at particular instant...

Present Federal regulations which specify maximum instantaneous circuit breaker settings for the short-circuit protection of coal mine trailing cables are discussed. Characteristics of mine power systems, which limit short-circuit current in dc trailing cables and minimum expected short-circuit currents for dc 300 and 600 V trailing cables, are analyzed. New maximum instantaneous circuit breake...

The up-gradation of an Electrical power generation network results in higher levels of short circuit fault current. Thereby, the existing protection equipment like circuit breakers, isolators and fuses become under capacity and not capable of withstanding higher short circuit currents. Thus the system is highly vulnerable to the adverse effects of short circuits. Replacing the whole protection ...
