KKS Power Plant Identification System — Overview and Implementation Guide

A. The System Code (Process-related)

This defines what the equipment is doing (e.g., Feedwater, Steam, Cooling). It consists of 3 levels:

  • Level 1 (Main Group): Single Letter. Defines the main engineering discipline.

    • A = Grid and distribution
    • B = Power transmission and auxiliaries
    • C = Instrumentation and control (I&C)
    • D = Heavy current equipment
    • E = Conventional thermal engineering (Main process systems)
    • F = Nuclear thermal engineering
    • G = Water treatment
    • H = Heating, Ventilation, and Air Conditioning (HVAC)
    • J = Waste treatment
    • K = Fuel handling
    • L = Civil engineering / Structures
    • M = Main machine sets (Turbine/Generator)
    • N = Operation & monitoring
    • P = Cooling water systems
    • Y = Auxiliary systems (General)

  • Level 2 (Group): Two alphanumeric characters defining a subsystem.

  • Level 3 (Sub-group): Two alphanumeric characters defining the specific function. kks power plant identification system pdf exclusive

Example Breakdown (System Code): Code: LAB

  • L = Civil Engineering (Main Group)
  • A = Buildings (Group)
  • B = Turbine Building (Sub-group)

3. KKS Structure and Principles

KKS is hierarchical and alphanumeric. Core principles:

  • Hierarchical locality: code reflects plant → unit → system → subsystem → component
  • Functional and physical distinction: identifies the functional role and location of items
  • Modular composition: composed of predefined code groups with fixed lengths and semantics
  • Extensibility: allows project-specific extensions while retaining core semantics

A typical KKS code is formed from blocks; common blocks include: KKS Power Plant Identification System — Overview and

  • Plant/Power Station code (1–3 letters)
  • Unit/Group number (numeric)
  • System code (3 characters) — main process or discipline grouping
  • Subsystem code (2–3 characters) — narrower functional area
  • Component code (3 characters) — type/class of equipment
  • Instance number (sequence/position) — unique instance of a component type

Example (illustrative): PLT-01-ABC-DE-XYZ-001

  • PLT = plant
  • 01 = unit 1
  • ABC = system
  • DE = subsystem
  • XYZ = component class
  • 001 = specific instance

Note: Exact block lengths and separators vary by KKS implementation; projects must publish their project-specific code manual.

4. Core Code Groups (Commonly Used)

  • Location/group codes: plant, unit, area
  • Systems: e.g., boilers, turbines, cooling systems, electrical distribution
  • Equipment classes: pumps, valves, heat exchangers, switchgear, transformers
  • Instrumentation tags: sensors, transmitters, controllers
  • Electrical tags: busbars, feeders, breakers, relays
  • Documentation and drawings: referencing drawings, cable schedules, loop diagrams

B. The Unit Code (Location / Spatial)

This defines where the item is located physically. It is typically a single-digit number (0-9). Level 1 (Main Group): Single Letter

  • 0 = Plant-wide / Common to all units.
  • 1 = Unit 1.
  • 2 = Unit 2.
  • A-Z = Used for trains or sub-units if numbers are exhausted.

Example: LAB 10

  • Building: Turbine Building (LAB)
  • Unit: Unit 1 (10)

4. Applications

  • Asset Management: Linking maintenance records to tags.
  • P&IDs and Drawings: Consistent labeling across documents.
  • CMMS/EAM Systems: SAP, Maximo integration.
  • Safety & Isolation: Clear identification for lockout/tagout.

The KKS Power Plant Identification System: Structure, Application, and Benefits

1. What is KKS?

KKS stands for Kraftwerk-Kennzeichensystem (Power Plant Identification System). It is a standardized identification system for power plants, developed by VGB PowerTech. It provides a common language for engineers, operators, and maintenance teams to identify everything from a whole unit down to a specific sensor on a valve.

Why is it used?

  • Standardization: A pump labeled 10PAB01AP001 means the same thing in a coal plant in Germany as it does in a nuclear plant in China.
  • Data Management: Essential for CMMS (Computerized Maintenance Management Systems), spare parts tracking, and root cause analysis.
