POWER SYSTEM MODELING

EHL’s Power System Modelling services use the latest version of ETAP, an advanced power modelling software package to maximise energy efficiency and ensure sound engineering practices. Use of this package also allows for easy modification of designs.

Outputs include:

• Load Flow Analysis
  
• Static and Dynamic Motor Starting Analysis
  
• Protection Device Coordination Analysis
  
• Protection Grading Reports
  
• Assistance with implementation of Protection Settings

EHL offers supporting services in the form of Service Level Agreements, which provide for systems models to be kept updated and assist with the implementation of protection settings and guidance with expansion of systems.

The above expertise extends into Mining, Process Plants, Parastatals and Industrial Development
