Electrical power systems analysis is a very broad subject that covers various elements in electrical engineering. In order to analyze the operation of power systems for any fault current and Arc Flash incident, we do need a proper Power systems study which involves the following:

1. Load Flow and Power Factor Study

2. Short Circuit Study

3. Motor Starting Study

4. Transient Stability Study

5. Snubber Circuit Study

6. Harmonic Analysis

7. Protective Device coordination study

8. Arc Flash Hazard Analysis

   
   

   What is a Power Systems Study?

   "A power systems study is made up of various engineering analysis investigations. The goal of each study is to have a safe, efficient and reliable power system for your facility under both normal and abnormal conditions."

   
   

   In order to perform Power systems studies, design engineers and power systems engineers are required who must have a high degree of understanding on proper application as well as a depth of understanding on power systems.

   
   

   Important Goals of Power Systems Studies

   A power system comprises of the various subsystems that include generation, transmission, and distribution. The goals of power system analysis are the following:

   1. To model or to execute per phase analysis of power system components

   2. To monitor the voltage at different buses, real and reactive power flow between buses

   3. To plan future expansion of the current system

   4. To analyze the system under different fault conditions and based on different Scenarios

   5. To design the Protective Devices, as well as to investigate the ability of the system to handle small and large disturbances or faults of any kind.

      Benefits of Power Systems Study

      As we already know that the reliable and safe power systems are critical for any successful operation. A well-designed power system ensures robust performance and maximizes plant availability under all operating conditions, including transient conditions like motor starting, non-linear loads and generator loss.

      Effects of poorly designed systems including outages, faults, poor power quality and Arc Flash over can results in a significant loss, or worse, personnel injuries.

      Power Systems Studies is a vital study for a secure and safe electrical supply. A typical power system study may incorporate any or all of the following sub-studies:
