RDS-PP-EXCEL-EN (2022-12) - Letter Code: System Key,Basic Functions and Product Classes - as Excel-table; approx. 10,250 data sets: letter code - explanation.
The basic international standards for reference designation provide users with gen-erally applicable general rules and letter codes for main classes for the designation of technical objects and their documentation.
The standard for power plants establishes sector-specific specifications based on the basic standards, and also includes options to enable application for different power plant types.
The fulfilment of specific designation tasks and addressing of collections of information necessitates coding systems which establish a relationship between the ob-ject names and letter codes.
For the designation of power plant systems, table 3 of IEC 81346-2 provides a framework for the designation of "infrastructure objects". This Guideline, VGB-S-821-00-EN, assigns the power-plant-specific systems to letter codes based on this framework (English edition, German language edition also available here ...).
Remark: The complete RDS-PP® covers the publications VGB-S-821-00-2016-06-EN "RDS-PP Letter Code for Power Plant Systems (System key)" and VGB-B 102 "Reference Designation System for Power Plants, Letter Code for Basic Functions and Product Clases" as well as special technology related VGB-Standards of series VGB-S-823; additionally the VGB-B 108 d/e "Guideline Rules for the creation of denominations and their application for power plant engineering" and VGB-S-891-00-2012-06-DE-EN "VGB abbreviation-catalogue for power plant technology" are recommended.
