Abstract: This article conceptually reviews the technological process of heat network intervening substation’s operation process. It presents the substation’s operation process optimization method to increase the system energy efficiency at large. Experimental data, that prove the effectiveness and expediency of suggested heat network operation methods, are presented in a graphic form.

Abstract: The problem of development and design of the wind power plant with a capacity of 5 MW. The scheme of compensation for active and reactive power of the drive motor is proposed, the scheme included double-fed electric machine.

Abstract: The paper shows the relevance of the research process protections of power units that reduce or prevent economic damage caused by the accident. For this data, the design methodology for coal-fired units with drum boilers, which allow to define the work on stored energy boiler auxiliary load. The proposed technique reduces the cost of implementing the considered technological protections.

Abstract: This paper briefly describes the main issues that are happening due to the usage of traditional systems of technical water supply at power plants, both from operational and environmental points of view. The article also presents an alternative option, as an air condenser, and the analysis of the using of such technology.

Abstract: Sources of financing actions on rising energy efficiency are considered and their contents and structure are defined. On the base of economic calculations the conclusion was made about impact of contents and structure of sources of financing on integrating efficiency indicators of projects of energy efficiency.

Abstract: The study is devoted to the issues of power price differentials for different groups of consumers. The factors have been identified to make a choice of the consumers’ groups in whose favour energy cost could be reduced. The set of the factors varies with regard to the government’s objectives: protection of vulnerable social consumers’ groups, or encouragement of economic growth through industrial development. The relation between the energy cost quoted for different consumers’ groups and national measures has been supported by statistical analysis.

Abstract: The mechanism of underground steel pipelines destruction by induced alternate currents in defects of waterproofing coat is considered in the article. Experimental assemblies have been developed to define the limit of qualitative change of character of degradation processes in steel under the action of alternate current. The change of processes’ character occurring on boundary “metal – electrolyte” with the increase of applied alternate voltage has been experimentally shown. For voltages more than 30 V the steel destruction becomes intensified by electroerosion phenomena.

Abstract: In the context of Russian power and transport modernization the problem of new ways searching of energy efficiency increasing based on area has been assuming significance and topicality within last years. The goal of authors’ research is the identification of current problems in the power engineering and transport sectors under modern economic conditions and the development of municipal education tendencies (directions) from the social and energy efficiency prospective. The number of state investment projects have been developed and justified from the economic and energy efficiency point of view. The proposed and justified directions and measures (actions) related to the implementation of state energy efficiency project on the area-based development will be helpful to State Government bodies. The research was carried out at the support of the program for strategic development of Novosibirsk State Technical University, project No C-31.

Abstract: The article investigates the problem of legislation in the field of energy conservation and provides an assessment of several of new legislation acts and development prospects. The authors analyze the Russian practice of energy service contracts, problems of contracts' content, as well as a subject of contracts. The authors investigate the possibility of adaptation of contractual structures, such as performance-contract that is used in an international energy services practice.

Abstract: The study sets the objective of overall overrun fuel separation into two components. The first one depends on changes in the electric load of the power unit. The second component is influenced by changes of the power unit controlled parameters. The separation leads to the adjustment of technical and economic performance of the power plant unit. These indicators show both the efficiency of the power unit and the overall plant.
