Fast transfer test of power station auxiliaries
There has been much work done concerning the analytical and theoretical analysis of bus transfers, most of this pertaining to the induction motor during transients; however, very little has been published presenting experimental data of such a transfer. In this paper data is presented which was taken during and after a bus transfer on a 450 MW fossil fired unit. The data shows the validity of the models, but also indicates that the synchronous motor is more of a concern than previously thought.
Analytical Studies Of Voltage And Current Transients During Fast Bus Transfer In A.C. Auxiliary System Of Thermal Power Station
This paper presents a powerful approach to analyse the voltages and currents during auxiliary bus transfer. A generalized computer program using multi-motor modelling suitable for analysis of a number of motors connected on the unit bus has been developed. In the first part of the study, auxiliary bus voltage decay and phase angle, speed fall of various motors, motor residual voltage and current and bus frequency are investigated at discrete time interval of 0.001 second. In the second part of the study the in-rush currents in the individual motors at different instants of closing of the reserve bus are predicted. Also, the bus-voltage recovery characteristic i s obtained. A test case is also illustrated.
REJOINDER TO BLOCK'S DEFENSE OF EVICTIONISM
I AM THANKFUL TO WALTER BLOCK (2010) for his comprehensive and perspicacious engagement with my critical remarks regarding his theory of evictionism (Wisniewski 2010). I also appreciate his kind words about what he sees as the merits and strong points of my argumentation. However, as one could easily surmise from my decision to write this rejoinder, I found his defense of evictionism unconvincing, though certainly informative and thought-provoking. Without further ado, let me now proceed to explaining why.
