Analysis of Computer Code and Method Used in Thermal-Hydraulic Safety Justification of VVER Reactor Plants

This article presents the analysis of the calculation procedure and computer code KLAST used in calculations of the control rod dynamic characteristics during safety justification of water-cooled water-moderated power reactor plants. The code allows accounting for pressure differentials as a function of time occurred under the design conditions on the reactor core and on the drive extension shaft as well change of coolant density in the core.

Electromechanical servo system with anisotropic regulator

A method of multiobjective synthesis for nonlinear multi-mass electromechanical servo systems with uncertain plant parameters based on feed-forward robust stochastic anisotropic control to improve the accuracy of such systems is developed. The method is based on the choice of the robust control target vector by solving the corresponding problem of multiobjective nonlinear programming in which the components of the target function vectors are direct quality indicators that are specified to the system in various modes of its operation.

Experimental Investigation of the Dynamic Processes of a Static Thyristor Compensator for a Mine Load Power Supply System

In order to improve quality of electrical energy in a 35 kV power supply network of a mining load, which feeds from busbars of district substation 330/220/110/35 kV «Novovolynska» of the Western regional electrical system, the static thyristor compensator of reactive power (STC) has been implemented. Conjoint operation of the STC and on-load voltage regulation device of a transformer of the substation allows resolving a task of comprehensive control of the whole power supply system (PSS) of the mining load.

Using elements of the theory of finite automata to study the dynamic properties of computer components of measuring systems

The results of research dynamic properties of computing components of measuring systems is considered. It is shown that the dynamic properties of computing components in the presentation Mealy machine arising due to the dynamic changes in input signals x (t). For the computing components to present Moore dynamic properties are determined mainly dynamic changes of metrological conditions computing components. A distinctive feature of Mealy machines is that their output signals depend on the state of the machine, and the value of the input signal.
