Specification for power and current transformers for use in aircraft electrical power supply systems

The article considers the features of design of industrial power supply system of metallurgical enterprises with on-site electrical power generation. The problems of increasing the efficiency of the main electrical equipment of on-site power plants are formulated. The analysis of development trends in the energy sector of Russian metallurgy is carried out, on the basis of which the importance of industrial on-site power plants is shown. The problem of choosing a generator automatic excitation control system of on-site power plants is con-sidered and possible ways of its solution are given. The task of regime optimization of industrial on-site power plants is considered and original optimization algorithms are presented. Methods of increasing the reliability of power supply of critical equipment and mechanisms involved in the technological process of thermal power plants are proposed. The urgency of the tasks of complex automation and digitalization in the industrial power supply systems is shown, while the special meaning of "digital twins" is noted. Possible prospects for the development of on-site power plants in the context of the decarbonization policy and the transition to alternative energy are considered.

The article deals with the issue of providing electric power to the first category receivers in the emergency mode of the power supply systems operation of perspective and modernized aircraft. The analysis of the published scientific works performed both in Russia and abroad, and aimed at solving problems of analyzing abnormal operations mode, synthesizing power supply systems and controlling them in order to prevent dangerous consequences is carried out. The authors considered the ingenious technical solutions aimed at providing the necessary quality power supply for the first category receivers in the emergency operation modes of the aircraft power supply systems for the safe completion of flight and landing. The research analysis and generalization of data on the technical characteristics of units and devices developed by the world's leading manufacturers of aviation equipment and used as emergency sources of electrical power on board modern civil aviation aircraft has been completed. The advantages and disadvantages of each technical solution are determined, as well as limitations to the area of their application are formed. The analysis of perspective emergency sources of the electric power including those, which previously were not applied in aviation because of their insufficient technical perfection, for example, hydrogen electrochemical generators is carried out. Based on the performed analysis, a solution which allows improving the operating modes of the electrical batteries is proposed. The offered solution makes it possible to increase the reliability and durability of electrical batteries, as well as the power supply duration of the first category receivers from them.
