3. Industrial Internship Project
SYNCHRONIZATION/ GENERATOR PROTECTION WORK SEQUENCES:
The existing modules, cables &
cores termination for CHA 11/12/13
panels are verified based on existing
drawing and cable schedule.
1.
3.
The synchronizing relay
parameterization (Automatic
Paralleling Device – D01 & Sync
Check Relay – D02) are set up.
2.
3. The cable terminals are
disconnected and the old modules /
components are removed.
The new modules / components
are installed in the panel and the
cables & cores are connected based
on the new cable schedule.
re 3. Industrial Internship Project
SYNCHRONIZATION/ GENERATOR PROTECTION WORK SEQUENCES:
Continuity check is done to
ensure the correct connection as in
new drawing.
5. Cold commissioning is done by
giving the input from HMI to see the
relay function as expected.
6.
Finding
1. Able to identify the tools used during dismantling and installing work.
2. Learn read the cores terminal, tagging, drawing.
3. Learn how to trace the cables with no tagging previously using
multimeter

2. Static Excitation
Equipment
3. Industrial Internship Project
START-UP FREQUENCY CONVERTER (SFC)
Function: Assist generator to accelerate the gas turbine set up to its operating speed. (3000 rpm)
Electrical auxiliary supply provide start-up energy from the grid.
Electrical generator operate as synchronous motor.
The converter shut down at 70% of the rated speed, gas turbine operates on its own. (2100 rpm)
3. Industrial Internship Project
STATIC EXCITATION EQUIPMENT (SEE)
Function: provides controlled DC-current and DC-voltage to the generator rotor winding in order to control the output voltage to the grid.
Generation of the magnetic field in rotor
Control of generator voltages to be according to set value during synchronization with the grid.

3. Industrial Internship Project
SFC/SEE RETROFIT WORK SEQUENCES:
All existing power, signal and
control cables are identified and
disconnected from the cabinet.
1.
3.
The brick wall at turbine hall
behind the PCC removable wall will
be broken and hacked.

There are cables with no tagging.
3. Industrial Internship Project
COLD & HOT COMMISSIONING:
1. Try to operate the gas turbine with No-Load & Full-Load test.
2. Combustion in combustion chamber is tested using fuel gas and fuel oil.
3. There are troubleshooting process done before the turbine can reach its
operating speed (3000 rpm).
3. Industrial Internship Project
COLD & HOT COMMISSIONING:
Second Firing First Firing
1. First firing: the speed of the gas turbine is increasing very slow, there is a time limit where the SFC will be off and the gas turbine trip automatically.

COLD & HOT COMMISSIONING:
3. Industrial Internship Project
COLD & HOT COMMISSIONING:
Second Firing
1. No-Load Test: The isolator of generator circuit breaker is in open condition.
2. Full-Load Test: The isolator is closed and the generator circuit breaker is
synchronized and connected to the grid.

HSE PRACTICE:
3. Industrial Internship Project
CONCLUSION:
1. The project is almost accomplish where the commissioning phase is now
towards the end.
2. The individual objectives are almost achievable :
Familiarized with the basic concept of power plant operation.
Learn about the theory and electrical design of Synchronization / Generator
Protection.
Learn about the basic theory of start-up and excitation system of a gas turbine.
Experience and assist the erection & commissioning works at site.
Implement Health, Safety and Environment (HSE) practices in the workplace.
3. Recommendation
Siemens:
More hands on task and training activities in the office and also at the project site.
UTP:
Provide a better and practical way of delivering the responsibility of the host company supervisor. (Ex: Briefing by UTP supervisor during 1st visit about the guideline – Internship Guideline 9.1.1)
Project:
Better enforcement of HSE practice at site.Prepare more power plant spare part in case of any emergency.
