The article touches upon reliability issues of energy management systems (EMS) of marine power plants in emergency situations caused by disturbance of the working media consumption and their subsequent recovery. The mathematical model of processes allows to determine the nature of changes in temperature and pressure of water and lube oil in EMS systems. The requirements to the characteristics of automatic control systems of the marine power plant have been formulated. Basic provisions of the reliability theory are followed by presentation of methods of calculating reliability indices of complex technical systems. The article presents the results of the study of non-stationary modes and reliability indices. Reasonable requirements for automated control systems were obtained through the analysis of working environments and of equipment operating in non-stationary modes, non-exceedance of safety limits of marine power plant operation being taken as the admissibility criterion. Besides, there are possible special modes resulted from emergency situations caused by the power plant equipment failure. Hence, for operation and design of the analyses it is important to study changes of working media in the circulation systems, which resulted from the failure of the pumps. Basic circuit of lubrication and cooling systems of the ship diesel power plants has been approved as recommended by the company "MAN B&W" for slow speed diesel engines standard series MC. Among the recommended schemes there was approved the scheme of the main engine with an autonomous cooling circuit. Schematic diagram of energy systems of a diesel power plant has been made under recommendations of the engine developer. Specifications of the component parts of the ship diesel power plant have been taken as standard for manufactured machinery. A low running L90MC-C four-cylinder main engine manufactured by "MAN B&W" was chosen as a research sample. A mathematical model, as applied to the given problem, consists of 10 algebraic equations for nonsteady working media consumption and 18 differential equations for nonsteady heat transfer in heat exchangers, as well as equations for transport delay in the lubrication systems of internal combustion engines.

The article describes the process of developing a turbogenerator for power plants of small and distributed power generation. The analysis of the component base for the turbogenerator was carried out, and thereof a comparative analysis of possible technical solutions was conducted. The work considered the installation variants of a turbogenerator in the exhaust system, an electric machine of a turbogenerator, types of turbines of a generator. A mathematical model for computation of the output effective and geometric parameters of a turbogenerator was described. The results of computational analysis were presented, and the parameters of the turbogenerator being developed were selected. Based on the results of the work done the conclusions were made
