Scientific principles, methods and techniques to reduce the impact of low-frequency oscillations in the power modes of the United Power System

Analysis of accidents in electric power systems (EPS) of the world has shown that one of the reasons for their occurrence is poor damped low-frequency oscillations (LFO). This requires solving of the complex problem aimed to reduce the LFO impact and increase the stability of the EPS. For the interconnected power system (IPS) of Ukraine, which is characterized by relatively weak interconnections in the conditions of rising of amount of distributed energy sources (RES) to solve these problems it is particularly important.

Increasing of working properties of the industrial components surfaces by applying modified nano-formation coatings

Increasing of operational properties, especially wear-resistant surface of industrial components may be achieved by modifying the surface layers of nano forms through the providing of nanopowders into the molten pool at electric-arc surfacing and coating during thermal spraying.

Development of GPS-systems of ultra-small space vehicles attitude control.

A new principle of attitude control system of ultra-small spacecraft (SKA) is developed, which is based on the determination of the spatial orientation of SKA by information of multi-antenna GPS-system and further usage of this information in the control loop of engine-flywheel (EF) - executing element of control system of angular motion of SKA. Methods and algorithms for determining the spatial orientation of SKA are investigated, as well as methods and algorithms for signal generation of the angular acceleration, which will significantly expand the resources of the precision of EF.

Surface topography modification by controllable laser irradiation
