Kukuy K. Modeling of modes of the group running-down and increase of the effectiveness of the nodes of the electric power systems with the impellent load.

Object of investigation - the processes in power supply systems with large induction and synchronous motors. The investigation aim - the stability increasing of power supply systems with large induction and synchronous motors. The methods - theoretical investigation are based on main assumptions of transient processes theory, mathematical simulations method, numerical calculation method of non-tinier allegorical and differential equation systems. Nowadays - the further development of transient processes analysis method in power system nodes with motor load and induction and synchronous motor behavior after group running-down, the nodes voltages calculations method of transient process for power system typical schemes with induction motors. The results - the computer programs of running-down and self-starting of induction and synchronous motor in power system load nodes are developed. The devices for back switch-on controlling in power supply system are improved. The methods of choosing additional flywheel masses of response electrical drive are developed. The results of transients process simulations at the unit auxiliary schemes and back switch-on devices are transferred to the Mironovskoy, Starobeshevskoy and Kurakhovskoy thermal power stations , and also using in studding process at the Donetsk national university. Branch - electric power industry.
