    (2019) Mahmoud, M. S. Al-suod; Abdullah, M. Eial Awwad; Mohammad, S. Al-arni; Alaa, M. Al-Quteimat; Ushkarenko, Oleksandr
    Abstract: The work consists of the development of the clarified model of a gas-diesel device by taking into account its design features and the influence of the turbo-supercharger. The analysis of the influence of the turbine on the physical processes occurring in the gas-diesel device, on the basis of which positive feedback on the torque on the shaft of the gas-diesel device is introduced, has been carried out. The process of parametric optimization of the PID-controller of the gas-diesel device has been automated to ensure high performance of the control quality in dynamic modes of its operation. As a result of modeling, oscillograms(records produced by an oscillograph or oscilloscope.) of transients before and after optimization of the controller have been obtained.

    Research of the Data Exchange Processes during the Automated Control of Autonomous Electric Power Systems
    (2020) Alaa, M. Al-Quteimat; Mahmoud, M. Al-Soud; Abdullah, M. Eial Awwad; Atia, AlHawamleh; Mahmoud, Zeidan; Ushkarenko, O.; Dorohan, O.
    Abstract: The article proposes a technique for studying the information exchange processes between the elements of the automated control system of the autonomous electric power system (AEPS). The analysis of information flows in the network of the distributed control system AEPS, which are formed by the software components of the automated workplace of the operator, and transmitted to the hardware automation means has been performed. The use of queuing theory allows to estimate the possibility of real-time system operation. The obtained analytical expressions, which allow the calculation of the average queuing time of the queuing system, are used to select the scan period in the SCADA system, which does not result in the loss of data packets. An analytical relation autonomous between the complexities of the AEPS scheme, which is used as part of the operator’s automated workplace for the automated control of the AEPS, and the workload of the communication channel has been established. It has been proposed to use an integrated complexity indicator of circuit for comparison of the AEPS schemes in terms of the load on the information channel.
