Power Systems B: Introduction to Power System Load Models

Understand the way customer loads interact with electric power transmission and distribution systems during the performance of your routine job duties. Get an introduction to the way motors, light bulbs, power supplies, heaters, etc. are modeled when various calculations are developed.

This half-day, PDH-booster course is part of a three-course group that allows you to earn 28 PDHs in just one week. Take it in combination with the three-day Power Systems A course, and the half-day Power Systems C course (also a PDH-booster) to complete the 28 PDHs. This course can also be completed individually.

Still looking for more? Enroll in our online Engineering Ethics course for two additional PDHs, bringing your total to 30 PDHs in just one week.

Benefits and Learning Outcomes

  • Discuss normal operating conditions, peak load conditions, energization, cold load pickup and FIDVR
  • Analyze incandescent, mercury vapor and LED lights
  • Cover induction motors, air conditioners, power supplies and lumped loads

Course Outline/Topics

Operating conditions that will be discussed include:

  • Normal operation with load diversity (some loads on, some loads off)
  • Peak load conditions with reduced load diversity
  • Initial energization (single motor starting)
  • Cold load pickup (re-energization without load diversity)
  • FIDVR (Fault Induced Delayed Voltage Recovery)

Loads that will be discussed include:

  • Incandescent lights
  • Mercury vapor lights
  • LEDs
  • Induction motors (fan and pump motors)
  • Air conditioners
  • Power supplies for electronic equipment
  • Lumped loads
