The most granular level, identifying individual components like a specific valve or a sensor signal. Eskom Tender Bulletin Key Types of Identification

Platforms like ResearchGate or Academia.edu host research papers and engineering theses that include complete KKS code appendices.

The initial letters of Level 1 categorize the fundamental nature of the system. Familiarity with these main keys is vital for reading engineering drawings (P&IDs): Grid and distribution systems B: Power transmission and auxiliary power supply C: Instrumentation and control equipment G: Water supply and disposal systems H: Conventional heat generation (Boilers, fuel supply) M: Main turbine sets (Steam or gas turbines) P: Cooling water systems W: Renewable energy plants (Wind, solar, hydro) Example Breakdown: HAB10 AA001 H: Conventional heat generation HA: Pressure system (boiler) HAB: Economizer system HAB10: First sub-system/train of the economizer

Focuses on the physical location of electrical and C&I components within cabinets, panels, or consoles.

The KKS system uses three distinct types of codes to classify plant assets:

China began introducing KKS in the 1990s, and most new power plants now adopt it. Chinese authorities also issued the industry standard to align with international practices.

Every piece of equipment has a specific code.

All P&IDs (Piping and Instrumentation Diagrams) and circuit diagrams use the same nomenclature.

The system is divided into three distinct types of codes to cover different aspects of plant identification: Process-Related Code:
