Power System Study
The electrical power industry began with the operation of the Pearl Street Station in New York on 4 September 1882. This station used steam engines driving DC generators to supply an initial load of 30 kW for 110 V incandescent lighting to 59 customers. Modern power systems are some of the largest and most complex infrastructures built by man.
Power system studies are an essential tool in designing electrical power systems that are reliable, safe and cost-effective. Power system studies are used as an aid in the analysis and design of power systems. They are computer based software tools for the calculation, simulation and optimisation of power systems.
BESST use ETAP (Electrical Transient Analysis Programme) for power system studies. ETAP is a fully integrated AC and DC electrical power system analysis tool. Power system studies are important in determining the safety of the electrical system. The power systems study will identify any equipment which may be overloaded or under-rated. It will identify areas where the system may not operate within regulatory limits. It will provide an ARC FLASH analysis, which is important for determining the best work place health and safety procedures that can be applied.
