Official, comprehensive guidelines from VGB are primarily distributed under copyright. However, many major international engineering, procurement, and construction (EPC) companies publish their own abridged KKS standards and project-specific handbooks.
Identifies the physical mounting position of electrical and instrumentation devices (e.g., a specific slot in a control cabinet).
Identifies the main system or discipline (e.g., Water-Steam Cycle, Gas Turbine). It uses a three-letter format.
The KKS Power Plant Identification System (Kraftwerk-Kennzeichensystem) is the global standard for classifying and identifying equipment in power generation. Whether you are an engineer, a technician, or a student, finding a comprehensive is essential for understanding how modern energy infrastructure is organized.
To get started, here are some commonly used system letters in the KKS framework: Boiler System LA - LN: Turbine System MA - MN: Generator System PA - PH: Feedwater System QA - QN: Cooling Water System kks power plant identification system pdf free
Identifies individual elements like sensors, motors, or limit switches.
The KKS system laid the foundation for the newer RDS-PP (Reference Designation System for Power Plants) standard, governed by DIN EN IEC 81346. Summaries of these standards are often free to access online.
KKS is the backbone of modern plant information systems, ensuring unique, traceable identification across all phases of a plant's lifecycle.
KKS uses an alpha-numeric code (usually up to 15-17 characters) divided into four levels of hierarchy: Identifies the main system or discipline (e
The system relies on standardized letter classifications for systems and components. Understanding these keys is essential for reading any KKS reference manual: Grid and distribution systems G: Water supply and disposal systems H: Conventional heat generation (Boilers) M: Gas turbine plants P: Cooling water systems X: Ancillary systems Y: General infrastructure Benefits of Implementing KKS
Do you need a to start coding your own equipment, or a read-only reference manual ?
(Level 1, Letters): Represents the Feedwater System (under the "L" category for steam/water cycles).
Identifies the specific mechanical component or electrical electrical group (e.g., Pump, Valve). Whether you are an engineer, a technician, or
Identifies equipment according to its in the mechanical, electrical, or I&C process. It is the most important code for day‑to‑day operations because it allows tracking across all disciplines. The prefix sign "=" may be used but can be omitted if uniqueness is maintained.
Identifies the smallest parts, like a motor or a specific sensor signal. Three Types of KKS Codes
He initiated the search, his fingers flying over the keys.
