Power Systems 104

Relay Commissioning II: Relay Schemes and Testing Calculations

April 15 - 17, 2019 | Nashville, TN

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 / 1 CTD

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

 

Introduction to Basic Logic Functions / 1 PDH / 1 CTD

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

 

Discovering Transformers / 2 PDH / 2 CTD

  • 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 / 1 CTD

  • 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 / 1 CTD

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

 

Reactance Changes Everything! / 2 PDH / 2 CTD

  • 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 / 4 CTD

  • 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 / 4 CTD

  • 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 / 2 CTD

  • 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 / 2 CTD

  • 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 / 2 CTD

  • 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 / 2 CTD

  • 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

Testimonial 

“Mr. Ashton’s lectures on power systems protection is easy to understand and very clear. I highly recommend his class to all individuals who want to learn more about protective relay philosophies, commissioning and testing.”

“This class is excellent. It should be an absolute addition to any corporations’ training program. I had the recent privilege to experience Rick’s class, and after being in this field for 12 years, I was able to relate to the topics discussed, and learn some new information as well.”

“I enjoyed the bus differentials protection. This particular section helped bridge the gap between what I do daily at work and what was taught when in college.”

“Michael did a fantastic job of conveying the complex concepts in a manner that anyone can understand without boring the people who already have a solid understanding of the material.”

“It takes a somewhat overwhelming amount of information and breaks it down into easy steps to follow.”

“Very good overview that had enough depth to answer the questions I didn’t even know to ask.”

“Mr. Young is very knowledgeable on this subject. It is clear that this information is second nature to him.”
