Introduction

Analysis of the standard core framework

Identification type	Structural composition	Application scenario	Example
Process-related identification	Prefix + 4-level coding (full station code/system code/equipment code/component code)	Photovoltaic panels, inverters and other core equipment	=$1WBA001GB001-B01
Installation point identification	Prefix + 3-level coding (full station code/installation unit code/space code)	Equipment positioning in electrical cabinet	+YAKA01,A01
Location identification	Prefix+3-level code (whole site code/building code/room code)	Spatial positioning of building (structure)	*YUWC01R01

Key technical elements

1. Coding character specifications

A combination of numbers (N) and uppercase letters (A) is used, and I/O letters are prohibited. The prefix is selected according to the application scenario:

Process identification: PV units ≤ 16 use "=$", > 16 use "#"
Installation point identification: fixed use "+"
Location identification: fixed use "*"

2. Principles of all-site code allocation

PV array identification

Complete coding: =$2WBA102GB003

$2: Photovoltaic unit No. 2
WBA: Photovoltaic array system classification code
102: The second sub-array under the No. 1 collector line
GB: Monocrystalline silicon component equipment
003: The third group of components in the array

Inverter component identification

Component-level coding: =$2WBA102GB003

$2: Photovoltaic unit No. 2
WBA: Photovoltaic array system classification code
102: The second sub-array under the No. 1 collector line
GB: Monocrystalline silicon component equipment
003: The third group of components in the array

Inverter component identification

Component-level coding: =$5WBC001GU002-B01

B01: Current sensor component (refer to Appendix E Table E.3)
GU: Inverter equipment classification code

Implementation suggestions

Design phase: Establish a station-wide coding list and mark the process identification in the system diagram
Construction phase: Make equipment identification plates according to Appendix E specifications and use anti-corrosion materials
Operation and maintenance phase: Establish a coding change process to ensure consistency between drawings and on-site
Special treatment: When there are more than 99 PV units, the coding rules need to be expanded in the engineering contract

Standard evolution analysis

This standard is different from GB/T The 50549 power plant identification system maintains a unified architecture, and adds:

Photovoltaic dedicated system code: WBA (square array), WBC (inverter system), etc.
Component subdivision rules: Monocrystalline silicon (GB)/polycrystalline silicon (GC)/thin film (GD) component classification
Intelligent operation and maintenance support: New system codes such as power prediction system (CPA)
