Dynamic stability of operating modes electrocentrifugal pumps installations

Authors: B.N. Abramovich, D.A. Ustinov, V.E Poljakov (Saint-Petersburg State Mining Institute)
Questions of definition boundary steady operation of electrocentrifugal pumps (EPI) are considered. Results of researches dynamic stability EPI, with usage model made on the basis of the equations, describing electromagnetic and electromechanical processes in underground electric motor are resulted. The dependences are revealed, allowing to define maximum permissible depth of failures of power in system of electrical supply EPI and power on an output of uninterruptible power supplies at which dynamic stability of technological process is provided.
