Operation Simulation of out of Step Relays Using Comtrade Files and Transient Stability Analysis
-The high interconnection levels of electrical systems is exposing them more to stringent operating conditions which can result in power oscillations and consequent system instability. Out to step protections are very useful to disconnect generators when genuine conditions of loose of synchronism arise and especially if the load loci crosses the impedance characteristics of the generators or th...
متن کاملA two-step rejection procedure for testing multiple hypotheses
This paper considers p-value based step-wise rejection procedures for testing multiple hypotheses. The existing procedures have used constants as critical values at all steps. With the intention of incorporating the exact magnitude of the p-values at the earlier steps into the decisions at the later steps, this paper applies a different strategy that the critical values at the later steps are d...
متن کاملOut of Step
This book will bring to many the memory of an interesting experiment carried out in the Army. This was an attempt to solve the difficulties of recalcitrant and anti-social youth?a problem which is rearing its head again in everyday life. The methods employed were carefully devised to trace the cause of delinquency and to help the individual to re-establish himself within a friendly, though disc...
متن کاملsalting-out procedure
DNA from archival Papanicolaou stained and unstained cytological smears was successfully isolated using a simple, rapid and inexpensive salting-out procedure. The quality of DNA was controlled by polymerase chain reaction (PCR) amplification of segments of the human P-globin, human P-actin and human papillomavirus LI genes. Only negligible differences in amplification efficiency were observed b...
متن کاملStep out with confidence.
The investigation found that falls were generally known to be a problem among those aged 65 or older. However, there was considerable variation in the way that the problem was acknowledged by people in this age group. Typically, those more accepting of the personal risk of falling had already fallen or had experienced aged-related health problems that significantly affected their lifestyle. Hav...
