description: InÂ  thisÂ  work,Â  theÂ  mainÂ  schemeÂ  ofÂ  electricalÂ  connectionsÂ  ofÂ  aÂ  pulverizedÂ  coal powerÂ  plantÂ  withÂ  aÂ  capacityÂ  ofÂ  4x500Â  MWÂ  isÂ  beingÂ  developed. WhenÂ  performing theÂ  work,Â  theÂ  mainÂ  electricalÂ  equipmentÂ  andÂ  theÂ  optimalÂ  structuralÂ  diagramÂ  ofÂ  the stationÂ  wereÂ  selected.Â  Short-circuitÂ  currentsÂ  haveÂ  beenÂ  determined.Â  CalculationÂ  of short-circuitÂ  currents.Â  BasedÂ  onÂ  theÂ  resultsÂ  obtained,Â  theÂ  mainÂ  switchingÂ  devices were selected, namely switches and disconnectors, buses and live parts, measuring currentÂ  andÂ  voltageÂ  transformers.Â  TheÂ  mainÂ  electricalÂ  connectionÂ  diagramÂ  ofÂ  the station was developed. Separately, the system of auxiliary needs of the power plant wasÂ  considered.Â  WorkingÂ  andÂ  standbyÂ  transformersÂ  forÂ  auxiliariesÂ  wereÂ  selected, short-circuit currents and heat impulses were calculated. Based on the results of the calculation,Â  switchesÂ  andÂ  cablesÂ  wereÂ  selectedÂ  forÂ  theÂ  stationÂ  auxiliariesÂ  sections. TheÂ  drawingsÂ  areÂ  presented:Â  aÂ  simplifiedÂ  diagramÂ  ofÂ  theÂ  technologicalÂ  cycleÂ  of electricity production, the layout of buildings and equipment on the territory of the powerÂ plant,Â  mainÂ  wiringÂ  diagram,Â  auxiliariesÂ  diagram,Â  outdoorÂ  switchgearÂ  plan, section along the cell of one of the outdoor switchgear.
