Power Systems 104

Relay Commissioning II: August 7 - 9, 2018 | Austin, TX

Training Curriculum

Power Systems 104 is an intense three (3) day course, eight (8) hours per day, which covers the following curriculum:

 

Applying Trig Functions to the World Of Relays / 1 PDH /

  • Trig functions used for meter and relay calculations
  • Law of sines used to find the boundary of alens characteristic
  • Law of cosines used to find “Delta-V” in Sync check relays

 


Introduction to Basic Logic Functions / 1 PDH /

  • AND gate and its equivalent DC circuit
  • OR gate and its equivalent circuit
  • NOT gate and its equivalent circuit

 


Discovering Transformers / 2 PDH /

  • Discovering the polarity of transformers
  • Discovering current transformers
  • Discovering that VA of transformers is the same on HV and LV sides
  • 87T relay schemes need to compensate for equal VA on both sides of the transformer

  • Delta-Y or Y-Delta transformers have a 30 degree shift, where does it come from?
  • 87T relay schemes need to compensate for that 30 degree shift

 

 


Quadrant Diagrams, Math Operators and Directionality / 1 PDH /

  • When to use X-Y diagrams
  • When to use R-X diagrams
  • When to use P-Q diagrams
  • Discussion of power system events and faults

 


Converting Values for Relay Tests / 1 PDH /

  • Primary ohms to secondary ohms conversion
  • Polar coordinates to rectangular coordinates conversions

 


Reactance Changes Everything! / 2 PDH /

  • Watts calculation
  • VARS calculation (what is a VAR anyway?)
  • Line angle and power factor
  • Line constants, operating quantities, angle of max torque and operating characteristics

 


Calculating Phase-to-Phase Values / 4 PDH /

  • Step distance concept
  • Errors in protection systems
  • When to use the square root of three (and when NOT to)
  • Calculate any phase-to-phase value (without the square root of three)

 


Calculating Symmetrical Components / 4 PDH /

  • Positive sequence calculation
  • Negative sequence calculation
  • Zero sequence calculation
  • Fuse failure/ loss of potential circuits

  • Forcing neutral current
  • Directional units
  • Zero sequence detector circuits

 


Calculating Apparent Fault Impedance / 2 PDH /

  • Phase-to-phase fault calculation
  • Introduction to zero sequence compensation factor coupling
  • Phase-to ground fault calculation
  • 3-phase fault calculation

 


Impedance Plots / 2 PDH /

  • Draw load vectors or fault vectors on X-Y diagram
  • Perform the math from Ohm’s Law
  • Draw load Z or fault Z plot on R-X diagram

 


Views of a Fault / 2 PDH /

  • Phase vectors on X-Y diagram
  • Impedance plots on R-X diagram
  • Symmetrical component vector comparisons
  • Sine waves can be examined

  • Harmonics can be examined


Relays by the Numbers / 2 PDH /

  • Relays by IEEE device number
  • Discussion of Mho circles and testing device 21 relay
  • Discussion of 87T tests
  • Discussion of generic testing requirements for other relays by IEEE device number

  • Discussion of NERC PRC 5 requirements of microprocessor relays
