RDS-PP® Reference Designation System for Power Plants - Letter Code for Power Plant Systems (System Key) - Excel-table (English edition)

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 infor-mation 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.
