The appropriate architecture is defined by critical functions, load behaviour, maintenance paths and site conditions, as well as equipment ratings.
Power-continuity requirements
Provide remote visibility at distributed and unattended facilities
Maintain controlled continuity where grid quality is poor
Manage different levels of criticality within one architecture
Consider service access and spare-parts planning during selection
Critical loads
Telecommunications and data communications
Pumps, control and automation systems
Security, access control and emergency communications
Field sensors and critical auxiliary loads
PROPOSED ARCHITECTURE
A traceable chain from source to critical load.
Grid/renewables/generator
UPS or rectifier
Battery and DC busbar
Local AC/DC distribution
Remote monitoring and critical loads
This diagram shows a typical solution approach. Final topology is established using the load list, single-failure criteria, operating philosophy and approved project data.
ENGINEERING DECISIONS
Redundancy, protection and monitoring are assessed together.
Redundancy strategy
Local redundant power modules according to facility criticality
Separate supply paths for communications and control
Energy reserves covering site-response time after a fault
Protection strategy
Coordinated protection against lightning and grid surges
Cable and voltage-drop checks on long DC/AC circuits
Short-circuit, insulation and enclosure safety
Control and monitoring
Remote tracking of source, battery and load condition
Alarm priorities and communications-loss records
Trends, events and thresholds for maintenance
PROJECT INPUTS
