Load Flow Analysis

Objective

 To design a power system on ETAP  To analyze the load flow on ETAP

Equipment

 ETAP

Procedure

  1. Firstly open editor of ETAP. Drag a synchronous generator and open generator setting. Then set operation value to swing and rating to 150MVA.Connect to 11kV bus. Figure 2. 1 :Synchronous Generator Info and Rating
  2. On generator setting set Impedance/Model on Typical Data and tolerance at 10.Also check the inertia and select OK of generator setting.

  1. Connect a bus providing 11 kV to transformer .Go to transformer settings and set ratings and impedance at typical values. Here transformer is connected to step up the voltage. Also set power rating to 150MVA. Figure 2.3:Transfomer 1 Rating and Impedance
  2. Connect transmission line with bus 2.Set transmission line 1 length to 200 ,tolerance to 10, parameter and Configuration.
  1. Set the Transformer 2 voltage rating (primary 550kV, sec 220kV) and power rating 150MVA. Also set Impedance at typical values. Figure 2 .6:Transformer 2 Rating and Impedance
  2. Connect transmission line with bus 4.Set transmission line 1 length to 220, tolerance to 10, parameter and Configuration. Figure 2.7:Transmission Line 2 Info

Figure 2.8:Transmission Line 2 Parameter and Configuration

  1. Set the Transformer 3 voltage rating (primary 220kV, sec 11kV) and power rating 150MVA. Also set Impedance at typical values. Figure 2.9:Transfomrer 3 Rating and Impedance
  2. Now connect 11kV Bus with Lump Load and set 100MVA rating by selecting nameplate.
