“…Due to the simultaneity of two cycles (gas turbine one and steam-power one), the combined cycle gas turbine (CCGT) unit, including an HRSG, has the power generation efficiency of about 60% (Kolpakhchyan, Shaikhiev, & Kochin, 2018;Kolpakhchyan, Zarifian, & Andruschenko, 2017;Qinghua & Fang, 2011;Yatsenko, Goltsman, Smolii, & Kosarev, 2015).…”

At present, the share of energy collected from renewable resources and low-power units is growing, and the generation becomes distributed, having many facilities that operate in co-generation mode. That is why the construction of an energy system with distributed heterogeneous sources and the improvement of its efficiency have become widely discussed issues. This paper proposes a solution of a local smart energy systemfortheTechnoEcoPark, a sciencepark of Rostov State Transport University, Rostov, Russia. The solution aims to integrate the distributed generation facilities, including environmentally friendly renewable resources, grid infrastructure and consumers with controllable and uncontrollable load. Theapproachtothe problem is the application of a smart control systemthatmanagesgeneration, distribution and consumptionof energy in a mini-CHP-based autonomous energy system. Such smart control systems reveal the trends of optimal energydistribution in a autonomousenergysystem. The study substantiates that installation of an in-house mini-CHP can solve the task of supplying heat and powertotheTechnoEcoPark. The important advantage of the solution is a significant reduction of expenses on energy consumption as the generation costs less compared to the grid tariffs. The proposed energy supply system of the TechnoEcoPark exemplifies the integration of heterogeneous heat and power sources and consumers into a commonnetwork. The paper outlines the mechanisms of the energy system efficiency improvement. These mechanisms make it possible to provide heat and power supply services to consumers and to return the generated power into the centralized grid. The materials of the paper can be of use to the specialists and researchers who are interested in generation and distribution of energy in autonomous systems.

“…Reducing electrical losses and improving energy efficiency are priorities [16]. Efficiency improvement can be achieved by using a systematic approach to the analysis of electromechanical processes [17]. The method based on the combination of newly developed diagnostics methods allow constantly monitoring the technical condition of the stator winding and detecting its damages at an early stage of their development.…”

Up to 38% of asynchronous motor (AM) failures are caused by damage to the stator insulation. Despite the wide variety of methods, the reliability of determining the inter-turn short circuits of stator windings under operating voltage still remains at a low level. The existing methods for diagnostics of asynchronous motor failure of the interturn short circuit of stator winding have been examined. New diagnostic methods for individual parameters developed in the course of the previous study are described. A new diagnostic method is formulated, on the basis of which the research work is carried out. The method will allow us to constantly monitor the technical condition of the stator winding, and identify its damage at an early stage of their development. Diagnostics can be performed without dismantling the engine and without removing it from the working process. The microprocessor unit is implemented for diagnostics of the technical condition of AM introducing this method. Moreover, the software and hardware complex is implemented for diagnostics of the technical condition for AM. The results of experiments on a laboratory stand with inter-turn AM closures are presented, which confirm the higher reliability of monitoring.

“…However, their main advantage is a capability to implement software-oriented models that make it possible to perform calculations of dynamic processes rather quickly; given the modern level of technology, even close to real time. That makes it possible to use them as a basis for algorithms that control microprocessor systems of automated drives of different types [12].…”

“…Typically, using numerical methods, such as a finite-element method [15], is proposed for it. The magnetic field parameters, obtained in this way (flux linkage and its derivativesthe differential inductance and a coefficient for counteracting electromotive force (CEMF) [12,15]), identify the mathematical model. These models are significantly better at describing the processes in an electromechanic transducer; however, the computational cost increases considerably.…”

The dynamic parameters of shock absorbers predetermine traffic safety and electric rolling stock speed in the intracity and rail line transportation. The smooth movement and dynamic performance of rolling stock are affected, first of all, by the type and structure of oscillation absorbers. The best indicators in terms of motion smoothness are demonstrated by pneumatic shock absorbers [1]; their use, however,
