Evaluation of Transmission Grid Voltage Impact on the Operation of Power Units’ Auxiliary Systems
Journal Title: Acta Energetica - Year 2015, Vol 25, Issue 4
Abstract
This paper presents the low voltage impact on the operation of critical auxiliaries of selected generation units in the national power system. Time limits are determined for the operation of these auxiliaries at low voltage in the power system and the acceptable reduced voltages in their secondary circuits at which the generation unit is capable of interoperation with the system. Upgrades of auxiliary systems are proposed which would enable interoperation of the unit and the system at significantly reduced system voltages.

Effect of dE-NOx techniques employed in thermal power plants on fly ash properties
Coal fly ash, a by-product of coal combustion in thermal power plants, is one of the most complex and abundant of anthropogenic materials. For several years, fly ash has predominantly been used as a substitute for materi...
A Method of Power System Static Stability Analysis
The paper reports on a study of changes in a power system’s operating parameters under a rise in its load. The results of these and similar studies may lead to an expansion of current views on a grid’s stiffness, its sta...
