  Techno Economical Calculation

  
  
  This video and study case demonstrates the techno-Economical Calculation Function. Two variations including grid expansions are provided each containing it’s own economic data. The Techno-Economical calculation and the Efficiency ratio calculation DPL script are executed for each alternative expansion in turn and the results are examined and compared in the output window....

  Transmission System Contingency Analysis

  
  
  There is one study case in the contingency folder (High Load), which is related to the corresponding operation scenario. The two variations defining the wind parks are active (“Stage 1 WPEast” is set as recording). The contingency analysis is performed using the “Single Time Phase Option” and considering all the N-1 contingencies for lines and transformers....

  Cable Sizing Analysis

  
  
  In this study case a single feeder has been defined. A cable sizing calculation can be carried out on this feeder in order to improve the results associated with the feeder coming from load flow calculations against thermal loading, short circuit and voltage constraints. A library of cable types has been provided in the project library....

  Transmission System Load Flow

  
  
  The example system describes a 225/90 kV transmission system. Loads are distributed throughout the network, but mainly concentrated at the 90 kV substations. Power plants are connected via step-up transformers to both 225 and 90 kV substations. Long 225 kV transmission lines are compensated with line reactors and some loads are shunt compensated. Two wind turbine groups are also considered (East and West).

  Feeder Load Scaling

  
  
  In this example a load flow should first be calculated. Notice that feeders are defined throughout the network. Define a voltage profile for a particular feeder noticing that the associated graphic is an active graphic. It is possible to edit the plot parameters and the colouring of each branch in the diagram according to the loading variable of the load flow results.
