In this paper an innovative algorithm for the transmission line parameter estimation is presented. The important factors, such as synchronisation, processing of non-stationary signals and phasor estimation that are affecting the estimation accuracy have been addressed in the paper, and the set of pre-processing tools have been proposed. The new algorithm is tested using practical fault records....

The behavior of a railway traction squirrel cage induction motor under rotor fault conditions is simulated by a complete phase model. A simple and direct procedure for model parameters identification by finite elements method (FEM) is described.

This paper presents the fault detection algorithm using regression method for plural indoor units faults of multi-heat pump system under heating mode. To develop the fault detection algorithm, experiment was performed under no fault mode. Total 65 experimental data were obtained from the experiment. Regression models for five heat exchangers which including one outdoor unit and four indoor unit...

The purpose of this investigation was to compare accuracy and precision of variance components and breeding values for international genetic evaluations based on national breeding values or animal performance records. A conventional progeny test scheme was simulated for 3 countries. True breeding values and observations were generated specific to production environments. Two production environm...

This paper describes a new method for harvesting maximum electrical energy in wind farms. In proposing technique, the stochastic process principles are applied for detecting fault measurements of sensors. On the other hand, the wind farm is modeled by using fuzzy concept. Thereby the turbines are controlled against continuous changes in speed, direction and eddy currents of the blowing wind. To...

Distributed hardware systems can be considered as teams of distributed cooperative agents. Thinking this way, will power the designers to develop new agent-based ideas to increase systems’ fault tolerance. In this paper, recovering the system from potential faults by helping the faulty agents in performing their tasks is considered. Besides, each agent, through two phases of distributed decisio...

Warning of imminent ground shaking due to a large earthquake would be useful to a variety of agencies. This kind of ground-motion prediction is possible in southern California for events with magnitude less than 6, where path effects dominate. The 28 June 1991 Sierra Madre earthquake is presented as a test case for this concept. A single-station inversion of the record from the Pasadena station...

A hardware based approach to Fault Emulation independent of the logic emulation system in use has been developed and is presented in this paper. Fault injection into a targetted circuit is made possible with the introduction of additional logic. The stuck-at-fault model is simulated with the method described here, which may also be used for multiple faults and bridging faults [1]. This discussi...

Protection of Extra High Voltage (EHV) multi-terminal circuits in power systems is complicated due to non-availability of measurements at the tap points. Locating a fault in such circuits is an important task for post-fault repairs or identification of weak spots in the system. This paper presents a new fault location scheme for an EHV multiterminal circuit. The proposed method utilizes synchro...
