Unit Protection Study Awarded for Large Industrial Power System

Protection validation initiated for a complex industrial electrical network

Power Projects 33 kV / 11 kV / 6.6 kV 3-Week Delivery ETAP Simulation

Power Projects has been awarded a Unit Protection Study for a large industrial facility comprising multiple voltage levels, distributed generation systems and process-critical electrical infrastructure.

The study will be executed using ETAP-based simulation to assess protection performance, validate fault isolation capability and support reliable system operation under fault conditions.

This engagement further strengthens Power Projects' experience in delivering protection engineering and power system studies for complex industrial networks.

Project Overview

The industrial power system includes multiple voltage levels and distributed generation, serving process-critical loads across the facility.

33 kV distribution system
11 kV distribution system
6.6 kV distribution system
Multiple transformer configurations
DG-connected sections & auxiliaries
MCCs, PCCs & process-critical loads

The objective of the study is to verify protection system performance across the network and identify areas requiring improved coordination, coverage or operational reliability.

Technical Scope & Methodology

The study will involve detailed review, validation and assessment of the existing electrical system model and protection configuration.

ETAP Model Review & Validation

  • Review of ETAP simulation model provided by the client
  • Validation of system configuration, connectivity and operating conditions
  • Verification of equipment ratings and network parameters

Protection System Assessment

  • Protection coverage across transformers, feeders and bus sections
  • Assessment for DG-connected systems and auxiliary networks
  • Review of protection coordination and fault isolation capability

System-Level Protection Verification

  • Simulation-based assessment under fault conditions
  • Identification of unprotected or weakly protected sections
  • Verification of selective fault clearance and system response

Recommendations & Reliability Improvements

  • Identification of protection gaps and operational risks
  • Recommendations to improve protection reliability
  • Support for safer operation of process-critical loads

Supporting Reliable Industrial Operations

In industrial facilities, protection performance plays a critical role in maintaining operational continuity and reducing the impact of electrical disturbances. Well-coordinated protection systems help:

Isolate faults selectively without cascading outages

Minimise equipment exposure during abnormal conditions

Reduce unplanned downtime and production losses

Improve overall operational safety and system reliability

Through this study, Power Projects continues to support industrial clients with specialised engineering services for protection validation and power system reliability assessment.
