Diagnostics Algorithms for Analysis and Assessment of Steady States and Disorders in Electrical Networks

“…The problem of disturbances in electric networks is a problem that dates back to the very appearance of electric power networks. The theory of single-phase and three-phase electric machines was developed in the first half of the 20 th century by Steinmetz [10], Richter [11], Kron [12], Veinott [13], Schuisky [14], Bedefeld [15], Alger [16], Fitzgerald et al [17], Lyon [18], Say [19]-which are just a few names from hundreds of engineers and scientists who have dealt with this topic and published papers in this field. In these works, stationary states and transient performance of electrical machines (disorders: failures, disturbances ...) are analyzed.…”

Fourier Analysis for Harmonic Signals in Electrical Power Systems

“…To the analysis of the systems in the harmonic domain of the polyphase AC, the concept was presented by Nikola Tesla [26] in 1888, there was a competition between AC and DC systems. Steinmetz [27], Richter [28], Kron [29], Veinott [30], Schuisky [31], Bodefeld [32], Alger [33], Umans et al [34], Lyon [35], and Say [36] were the pioneers in the study of single-and threephase induction machines which published in this area of expertise, being the most recent Matsch [37], Chapman [38], and Fuchs et al [39,40].…”

Modeling and Analysis of Induction Machines

“…The steady-state stability criterion is [20] @T L @ω m > @T @ω m ; (3)(4)(5)(6)(7)(8) where T L is the load torque and T is the motor torque. Using this equation, the stable steady-state operating point of a machine for any given load-torque characteristic can be determined.…”
