The essence of the development is to create and test the system of monitoring and analysis of electric networks modes of operation and automatic control of electric distribution networks based on new methods of processing data of synchronous vector measurements, as well as experimental validation of the developed technology to determine the features of its application in power grids with renewable energy sources.
The main results of the work are:

An experimental electrical drive for electric buses and traks is developed and experimentally tested. Developed power converter for induction motor based electrical drive provides 100 kW of output power. Flux-torque (speed) control algorithms for induction motor are developed, implemented and experimentally verified. Developed nonlinear controller take into consideration motor's magnetizing curve provides asymptotic flux-torque (speed) tracking, torque per Ampere maximization (MTA) as well adaptation to stator and rotor resistances.

The theory of analysis and synthesis of adaptive electromechanical systems with vector-controlled electrical motors is developed and generalized. Proposed theory allows synthesizing automatic control systems with the properties of robustness to electrical motor parameters variations, thereby improving their dynamic performances and efficiency. Methods for robust adaptive estimation of immeasurable coordinates and identification of unknown parameters of electromechanical converters are developed.

The usage of the control system which is based on synchronously measured phase angles values of the nodal voltages will improve control reliability in load flow, decrease the transient time and prevent the asynchronous mode beginning.
