Hadaj A. Indemnification a reactive-power in the starting modes of asynchronous and synchronous drives

Subject of research - process of indemnification for reactive-power of sites of electrical networks in the starting modes of asynchronous and synchronous electric drives; purpose of research - by improving the voltage dynamic compensation of reactive-power during start-up of large asynchronous and synchronous electric drives; subject of research - methods and techniques for managing compensatory installations starting modes of asynchronous and synchronous electric drives; methods of research and apparatus - analytical, experimental; theoretical and practical results - new information systems options for creating dynamic reactive-power compensation to provide voltage in the starting mode of asynchronous and synchronous electric drives operating in the electricity networks of limited capacity; scientific novelty: expediency of the use of spectral conductances as informative parameters of the devices of dynamic reactive power indemnification to maintain voltage during start-up electric drives; improved mathematical model of analysis starting electric drives, which provide the criteria for obtaining fast reactive power indemnification; was further enhanced management devices dynamic reactive power indemnification on the basis of information on the spectral conductance of the load, which improves the accuracy and speed of indemnification of reactive loads; the degree of introduction - in the range of branch; field of introduction - enterprises of mining sphere.
