The main stakeholders in the gas distribution sector (government, shareholders and consumers) have different interests and goals. The state, as a regulatory body, should find the best regulatory methods in order to achieve the maximum effect of public welfare: direct (pricing) and indirect (price influencing). The use of the “costs plus” method makes it possible to set the lowest possible tariffs for the transportation of natural gas, but it leads to the emergence of a “tariff precedent”, a loss of profits for companies, limited investment in the development of the sector. In order to stimulate the increase in the efficiency of gas distribution organizations, the implementation of the fundamental principle of gas distribution sector regulation is proposed. The use of incentive regulation will help find a balance in setting prices for gas networks in order to cover the costs of companies, increase profitability, stimulate the development of networks and innovations, establish the optimal price for consumers.

The article deals with the principle of evaluation of technical condition, based on a comprehensive analysis of the motor parameters which is a main unit in mechanical engineering. Diagnostics system and residential life assessment of electromechanical equipment is presented based on the AC engine and algorithms of its work. The important challenge of diagnostics remains the well-timed faults detection and maintenance and repair organization. The solution of such challenge remains accuracy and reliability of diagnostic systems.

The frequency of maintenance of electromechanical equipment depends on the plant, which uses and runs this equipment. Very often the maintenance frequency is poorly correlated with the actual state of the electromechanical equipment. Furthermore, traditional methods of diagnosis sometimes cannot work without stopping the process (for example, for equipment located in hard to reach places) and so the maintenance costs are increased. This problem can be solved using the indirect methods of diagnosing of the electromechanical equipment. The indirect methods often use the parameters in the real time and seldom use the parameters of traditional diagnostic methods for determination of the resource of electromechanical equipment. This article is dedicated to developing the structure of a special automated control system. This system must use the big flow of the information about the direct and indirect parameters of the equipment state from plants from different areas of industry and factories which produce the electromechanical equipment.
