Development of military power causes need of increase in technological level of the capital equipment of power supply systems of military facilities, increases in reliability of devices of relay protection, automatic equipment and technical diagnostics, a solution of the problem of complex automation of control of actually military power supply system in normal, emergency and postemergency operation. In article it is offered during creation new and modernizations of the existing power supply systems of complexes of arms and military equipment to develop devices of relay protection, automatic equipment and technical diagnostics of the capital equipment of these systems to use contactless electric devices which design and development is carried out with use of a mathematical apparatus of algebra of logic in which it is offered to take temporary Boolean functions as a basis. Definition of temporary Boolean functions and temporary operators is given. Devices of relay protection, automatic equipment and technical diagnostics work in terms of use of various time lags and therefore the description their robots and synthesis of logical structure of these devices needs to be carried out with use of temporary Boolean functions and temporary operators. Therefore the main Boolean functions and examples of realization of temporary Boolean functions and operators of a delay are given in this article. An example of development of a logical part of relay protection of a system of uninterruptible power supply in which the store of energy is the inertial flywheel is reviewed, and the converter of energy is the synchronous electrical machine which depending on a condition of external input works in the mode of the synchronous electric motor, or in the mode of the synchronous generator. The scheme of a logical part of the device of relay protection of this system is provided.Downloads
