Application of New Design Automation in the Development of the Pregolskaya TPP Automated Process Control System

The article considers the methods for a hierarchical description of complex systems’ engineering, which is the foundation for aggregation and decomposition technology of structurally complicated electrical systems’ computer-aided design. The issues of technology application in the design of the automated process control system, the improvement of these methods, and the expansion of the class of designed systems are discussed. The technology development issue and its application in the automated design of secondary wiring systems in general and TPP essential auxiliaries in particular is considered. The process of introducing the automated design technology at АО Zarubezhenergoproekt, realized in the Elektrika TsVK CAD system, is described. The CAD-based technology was tested in the design of the 0.4 kV alarm and essential auxiliaries' control systems at the Pregolskaya TPP with 4 × 110 MW of electric power. The features of the design process’s organization at the Pregolskaya TPP are provided: the degree of the design institute’s equipment availability with technologies and design automation facilities at the beginning of the project, the assimilation degree of these technologies by the personnel, and the possibility of integrating existing technologies with the new developments. The issues of mutual adaptation of the new technology’s components and routine design procedures and operations existing in the design institute, information flows between the technology components and design groups, and structural units (departments) of the design institute are considered. The quantitative indicators of the information volume transmitted in the design process between the structural units of the design institute, as well as the volumes of design documentation developed in the CAD system, are given. The expected timetable to obtain a result using the new technology is indicated.
