Library of graphic symbols for power equipment in the scalable vector graphics format

This paper describes the results of developing and using a library of graphic symbols for components of power equipment under the state standards GOST 21.403-80 “Power Equipment” and GOST 2.789-74 “Heat Exchangers”. The library is implemented in the SVG (Scalable Vector Graphics) format. The obtained solutions are in line with the well-known studies on creating libraries of parametrical fragments of symbols for elements of diagrams and drawings in design systems for various industrial applications. The SVG format is intended for use in web applications, so the creation of SVG codes for power equipment under GOST 21.403-80 and GOST 2.789-74 is an essential stage in the development of web programs for the thermodynamic optimization of power plants. One of the major arguments in favor of the SVG format is that it can be integrated with codes. So, in process control systems developed based on a web platform, scalable vector graphics provides for a dynamic user interface, functionality of mimic panels and changeability of their components depending on the availability and status of equipment. An important reason for the acquisition and use of the SVG format is also that it is becoming the basis (recommended for the time being, and mandatory in future) for electronic document management in the sphere of design documentation as part of international efforts to standardize and harmonize data exchange formats. In a specific context, the effectiveness of the SVG format for the power equipment arrangement has been shown. The library is intended for solution of specific production problems involving an analysis of the power plant thermal circuits and in training of power engineering students. The library and related materials are publicly available through the Internet. A number of proposals on the future evolution of the library have been formulated.
