The paper considers the frequency load shedding of an electric power system. The objective of this paper is to enhance the structure and algorithms of frequency load shedding-1 (AUFLS-1) using cutting-edge technologies, namely Wide Area Measurement System. We model the operation of the system of complex power supply when various emergencies in the Power Factory software occur. We aim at revealing the fact of the voltage corner reaction on the emergency occurrence and elaborating the algorithm of detecting the emergency by speed of voltage corner change. The result and novelty of this research is that we propose how to upgrade the system AUFLS-1 by introducing the additional starting block reacting to the speed of the voltage corner change which increases the speed of AUFLS-1 system operation. As a result the system AUFLS-1 starts up not only by achieving "frequency" set point but also by analyzing the speed of voltage corner change. [ABSTRACT FROM AUTHOR]

This paper considers the method of temperature influence indemnification to image quality of optical systems working in the infrared range of spectrum for the case of homogeneous temperature distribution through the system. The simultaneous achromatization of focusing knot is possible when passive athermalization is used. Rational problem decision of athermal and achromatic optical system designing is possible when the triplet including specific compositions of optical materials combined with specific mechanical housing materials is utilized. The algorithm proposed allows obtaining athermal and achromatic three-component optical system by selecting necessary combination of materials. In addition, we give some recommendations on how to select the triplet materials based on the dependence diagram of optical and thermophysical materials properties. The method includes the influence of housing material expansion of focusing knot when the ambient temperature changes. We also consider examples of possible combinations of optical and mechanical materials for the infra-red waveband of spectrum of 3-5 and 8-12 μm. [ABSTRACT FROM AUTHOR]

In this paper we study and formalize the processes of the strategic planning. We define the algorithm to structure and evaluate the development scenarios of the object under research as a part of the strategic planning. In addition, we propose the methodology for choosing actors' policies to achieve the desired future state of the researched system. This methodology takes into account the factors of benefits, costs, opportunities, and risks. The methodology is based on the method of the hierarchy analysis, and utilizes the iterative application of the direct and reverse processes defined in this method. Moreover, we propose the solution to the problem of calculating actors' weights indirectly by the influence of the actors on the considered factors, namely the increase of benefits and oppotunities, and decrease of costs and risks. Finally, we reveal that an integration with other approaches to the management of the economic systems is required for applying our prediction evaluation methodology. [ABSTRACT FROM AUTHOR]

This paper considers the optimization algorithm of a digital control system on integrated quality criteria. The algorithm proposed allows performing parametrical synthesis of a digital proportional-integral-derivative control at the integrated quality criteria. Moreover, we calculate the integrated quality criteria of interrelation with character of transients in a control system. We also show the dependence of quality transients on the influence channel. Examples of the algorithm proposed are considered at modeling transients in a control system. Practically, this algorithm can be used by developers of automatic control systems for optimization of control systems. [ABSTRACT FROM AUTHOR]

The present paper proposes the control algorithm for the thermal mixing aggregate to stabilize a water level and temperature under non-stationary external disturbance (water consuming). We show that an additional coordinating control loop for outputs' ratio should be utilized to increase the control quality. The specific control laws for basic and coordinating regulators are proposed. Furthermore, numerical modeling is presented to ensure effectiveness of the present algorithm. [ABSTRACT FROM AUTHOR]

In this paper, we describe the conditions, providing the existence of splicing of the measures λ , μ and v - finite, finitely additive and integral functions of sets, defined on the algebras of subsets B and C of some set Ω and the algebra U, based on the algebras B and C . Moreover, we show that the measure λ should be a common extension of the measures μ and v , and λ(B∩C)= λ(B)λ(C) for any B ε B, C ε C. [ABSTRACT FROM AUTHOR]

In this paper, we consider the mechanisms for endowing the cellular automata (CA) models with the anticipation property. On the experimental side, we apply a widely known Conway's game 'Life'. The research results show that even within this simple model, the introduction of anticipation has a crucial impact on the behavior of the system, resulting in emergence of multiple co-existing solutions. Furthermore, the inherent behavioral templates of classical 'Life' (fixed point, cycle, chaos) are valid for its anticipatory version; however, they develop at a level of configurations' sets. Finally, we make the extensive computational simulations and present the most significant research results. [ABSTRACT FROM AUTHOR]
