19-26 362
Abstract
Main questions, themes, and solutions approved by the academic board of the Russian Academy of Sciences (RAS) have been set out.
27-34 421
Abstract
The role of energy in the development of society, the influence of energy consumption on the condition of ecology, and relation between ecology and economics have been shown. The ways of controlling the deterioration of ecology situation which is affected by process systems of the power industry, power consuming complexes and transport systems have been reviewed. Regarding the power conditioning thermal complexes the measures aimed at increasing energy efficiency and improving the ecology through compatible upgrading and re-equipping have been shown. Transport and gas distribution as a unified energy system has been reviewed.
ECONOMIC PROBLEMS IN THE ENERGY SECTOR
35-36 398
Abstract

STAFF TRAINING
37-42 437
Abstract
The personnel training issues for different age groups regarding formation of social mentality with respect to saving natural energy resources have been reviewed.
ENGINEERING, RESEARCH AND CALCULATIONS
43-52 488
Abstract
Methods of selecting the substation schemes by reliability data and based on the theory of factor analysis have been developed which enable to perform a more comprehensive and credible analysis of reliability of substation-to-electric power system connection scheme and select wiring schemes. Examples of selecting terminal and transit substation schemes based on the application of developed methods have been shown.
53-56 535
Abstract
The way of increasing the energy efficiency of a centrifugal pump based on the use of random pitch impeller system ensuring integral increase in the pump efficiency in the operating area has been reviewed. The pump operation modes and its operating conditions in which this upgrade method ensures a maximum positive result have been specified. The experimental data confirming efficiency of this method has been shown.
57-64 534
Abstract
Based on the analysis of operation experience, the results of model and field (plant) studies of intermediate steam separation and superheating systems of Nuclear Power Plant turbines, the problems have been specified and some possible ways of their improvement have been discussed.
65-69 445
Abstract
The results of calculation study of thermostressed condition of high pressure cylinder body of cogeneration steam turbine Т-53/67-8.0 of CJSC “UTZ” for Combined Cycle Power Plant CCPP-230 have been given. Zones which are characterized by maximum temperature stresses have been specified. Conclusions regarding reliability of approved turbine start technology in terms of thermal durability of High Pressure Cylinder (HPC) body have been given.
OPERATING EXPERIENCE
