Power Factor Circuit Design & Analysis - Rawang Terrace House

Click For Summary
SUMMARY

The discussion centers on designing a power factor correction circuit for a terrace house in Taman Maju Jaya, Rawang, with the goal of improving the power factor from its current values to 0.98. The electrical loads include fluorescent lights, air-conditioning units, and CFL lights, with specified active power and power factors. Participants suggest using simulation programs to verify designs and recommend researching power factor circuit diagrams and correction standards to aid in the proposal development.

PREREQUISITES
  • Understanding of power factor concepts and calculations
  • Familiarity with electrical load characteristics and specifications
  • Knowledge of simulation tools for circuit design
  • Experience with power factor correction techniques
NEXT STEPS
  • Research "design a power factor circuit diagram" for visual guidance
  • Explore "power factor correction standards" for compliance and best practices
  • Learn about "simulation software for electrical circuit design" to validate your proposal
  • Investigate "calculating total power factor" to understand the correction process
USEFUL FOR

Electrical engineers, students in electrical engineering, and professionals involved in power factor correction and circuit design will benefit from this discussion.

PLEASE HELP ME, GOOD ENGINEER :D

Problem Scenario

As an electrical engineer in Rawang Power Electrical Consultant Company, your boss assigned your group to design a power factor circuit to improve the low power factor in one terrace house in Taman Maju Jaya, Rawang. The terrace house received a power supply 240V, 50Hz from TNB. The loads in that house consist of :



Device , Units ,Active Power ,Power factor
Florescent Lights ,10 ,40W each , 0.5
Air-conditioning ,4 ,750W each , 0.7
CFL Lights ,7 25W each , 0.6


Your group needs to produce the best proposal on designing a power factor circuit to improve the power factor to 0.98 and verify your design with appropriate simulation program.
Compare the current, power factor, apparent power, reactive power and active power consumed before and after the power factor correction exercise.
Write a brief proposal contains the design and findings.

the problem is where should i start first, how to calculate total power factor and correct it to 0.98?
