If you are trying to understand how to label a specific component, or if you need to know the official coding, I recommend finding a complete KKS manual (PDF) to use as a reference.
Structured to allow users to drill down from an entire plant down to a specific electrical terminal. Understanding the KKS Coding Structure
KKS eliminates this confusion by assigning a unique, alphanumeric code to every single asset. This ensures that a civil engineer designing a building, a technician replacing a pump, and a software engineer programming the Distributed Control System (DCS) are all referring to the exact same object. Core Objectives of KKS

Developed by vgbe energy (formerly VGB PowerTech), the KKS provides a consistent methodology for designating power station components. It is used throughout the lifecycle of a plant: Ensuring clear, functional requirements. kks power plant identification system pdf
2. KKS Identification Types: Process, Installation, and Location
The final level identifies individual elements or parts of the equipment aggregate, such as a specific sensor, limit switch, or terminal box. Define the component type. Numeric Characters (BN): Sequential numbering for the part. Common KKS Function Keys (Level 1 Examples)
For existing installations, the current VGB standard remains VGB-S-811-01-2018-01-EN (8th edition), while RDS-PP® continues to be developed for future applications.
A typical KKS code consists of 15 to 17 alphanumeric characters divided into four breakdown levels (0 to 3). As you read the code from left to right, the detail increases: Power Plant Identification System (KKS) - Menger Group If you are trying to understand how to
KKS is designed to work across all engineering disciplines—mechanical, electrical, civil, and control engineering—ensuring consistent communication between different departments and contractors.
The KKS system relies on standardized letter blocks specified by VGB guidelines. While a complete index requires a full reference manual, here are some of the most common used in power generation: A: Plant Structures (Buildings, foundations, tunnels) C: Instrumentation and Control Equipment G: Water Supply and Disposal H: Conventional Heat Generation (Boilers, furnaces)
Practical diagrams showing how a physical piping and instrumentation diagram (P&ID) translates into a compliant KKS string.
China began adopting KKS in the 1990s, and today most new power plants in China utilize the system. The country has even developed its own industry standard (DL/T950-2005) based on KKS principles. This ensures that a civil engineer designing a
This code identifies specific installation points within electrical and control systems. It's particularly important for instrumentation, control panels, and electrical cabinets, allowing technicians to locate where equipment is physically installed.
Usually denotes the plant unit (e.g., Unit 1 or Unit 2).
A standard process-related KKS identification string is divided into four breakdown levels (Levels 0 to 3). Each level consists of classified alpha (A) and numeric (N) characters:
KKS has achieved remarkable global penetration, becoming the preferred identification system for power plants worldwide:
