Investigation of Permanent Magnet Fault Current Limiter for Electrical Power Application

Title
– Investigation of permanent magnet fault current limiter for electrical power application.

2. Background
Electrical power engineering expanding due to the addition of many renewable and sustainable
resources. That has a positive impact to the environment and global warming issues, however a
technical issue keeps raising due to the integration of these resources, like increasing the short circuit
level that current infrastructures cannot handle. many techniques have been developed to address
this issue, among these are the magnetic techniques in which high short circuit current could be
damped to an acceptable level that the current infrastructure could handle.
Permanent magnet Fault current limiter techniques is among the new promising technology to
address this issue. This project looks investigate a new PMFCL topology and asses the feasibility of
this proposed design.
3. Aim & Objectives
Test and investigate an existing prototype of PMCFL to obtain the main electrical engineering
parameter of devise and to establish its important electrical engineering characteristics.
4. Methods / activities
The method I will use to get all the work done is by conducting a literature reviews to the previous and
current technology in this field. One of the major plans is to analyze the existing design using FEM
software to evaluate the design characteristics. This will be followed by conducting a series of
electrical tests to obtain the characteristics.
1- Connecting the PMFCL circuit to the proper measuring equipment like ammeter and voltmeter.
2- Make sure the connections are right, double checked by staff academic or the lab technician.
3- Make sure the right rating of the cables and supply.
4- Make sure that I know where is the emergency CB in case of emergency
5- Make sure that the VARIC is at minimum value
6- Switch on the power supply and gradually increase the voltage to 50V in steps of 10V
7- Collect Ammeter and voltmeter reading at each step

8- Disconnect the circuit at the end
9- If you need to leave the lab for any reason. Make sure you disconnect the circuit from the
power supply by turning the switch off.
10- Disconnect the circuit after.
