the paper is devoted to solution of some problems in nuclear power station generating unit intellectual control systems using genetic algorithms on the basis of control system model development, optimizations methods of their direct quality indices and improved integral quadratic estimates. some mathematical vector models were obtained for control system multicriterion quality indices with due ...

To enhance the evaluation of the reliability recently featured many of the approaches linking the probability and fuzzy logic, the multi agent system can provide a connection between fuzzy logic and probability. In this article represents a new application of multi-agent model for evaluating the reliability indices of generation power system. Using agents of the probability for determining capa...

Digital substations are mostly important in the future of the electric power industry which makes their testing a critical process to ensure the required reliability and security of the grid. The paper introduces the definition of a digital substation and efficient testing, as well as the requirements for isolation during testing. It later describes testing related features in IEC 61850 Edition...

Aiming at the different sampling rates of multiple sensors for the real-time detection system of heat faults in high-voltage equipment in substation, the step by step prediction fusion algorithm based on synchronous sampling data was used to rapidly calibrate the location of thermal faults. And a new method that using infrared thermal imager together with CCD (Charge Coupled Device) camera and ...

We re…ne a conjecture of M. O. Locks and J. M. Wilson [Reliability Engineering and System Safety 46 (1994), 283-286] regarding disjoint forms of the Abraham Reliability problem. We also present other examples of reliability problems with the interesting property that their minimal disjoint forms do not arise from the familiar tautologyM1+:::+Mn M1+(M2 M1)+(M3 M2 M1)+:::+(Mn Mn 1 ::: M1):

Abstract Reliability and active power loss are two fundamental parameters in the design and planning of distribution systems that have always attracted the attention of power distribution systems designers and engineers. The improvement of reliability and the reduction of power loss are investigated as the primary objective functions and voltage profile as the secondary objective function. A me...

This paper presents a time-sequential simulation technique incorporating the effects of interruptions and voltage sags in the reliability cost/worth evaluation of distribution systems equipped with different overvoltage protection types. The interruption and voltage sag data for different overvoltage protection schemes was obtained from long-term measurements performed at a 110/20 kV substation...

Abstract The reliability and safety of any system is the most important qualitative characteristic of a system. This qualitative characteristic is of particular importance in systems whose functions are under various stresses, such as high temperature, high speed, high pressure, etc. A considerable point, which is rarely taken into account when calculating the reliability and safety of syst...
