1. Project title:
RELAY APPLICATION IN CONTROLLING MEDIUM VOLTAGE
ELECTRICAL CABINET SYSTEM AND INDUSTRIAL ELECTRIC DEVICES
2. Initial data and documents:
- D60 Line Distance Relay Instruction Manual.
- T60 Transformer Management Relay UR Instruction Manual.
- F650 Digital Bay Controller Instruction Manual.
3. Requirements of the project:
- Task 1: Research and study the details about relays D60, T60 and F650 in GEHCMUTE laboratory.
- Task 2: Research and study about specific supporting applications and software
such as EnerVista UR Setup, EnerVista Viewpoint Monitoring.
- Task 3:Taking relays’ experiments inside GE-HCMUTE laboratory (operation
and observation).
- Task 4: Study the details of relays’ program and operation function.
- Task 5: Planning and researching to build a module for simulating the
operation.
4. Final product:

model controlling on/off with D60 to

demonstrate Relays characteristics more clearly. Hence, help users
further understand relays operating principles in electrical system.
Weaknesses:
 The model is still quite simple.
 Need to study more on simulating other functions of D60 Relay.

5.3. DIRECTIONS AND AIMS FOR FUTURE DEVELOPMENT
OF THE THESIS TOPIC
In further studies on relays in GE - UTE electrical system, need to focus on
exploiting main protection features of relays. Can simulate faults and see protection
features of relays via Matlab Simulink or some microcontrollers converting relay
readable analog signals.
Research FlexLogicTM programming language, used for programming relays via
EnerVista UR Setup software which is free for anyone to use easily. Build control and
monitoring programs for devices connected to relays in electrical system.
Research and develop Modules for relays to control and monitor their operation
when Modules are connected to relays via rear output/input ports.
Learn more about software supporting testing, controlling and monitoring of
relays in GE - UTE electrical systems.
Learn about Remote Control of UR relays.

5.4 CONCLUSION
Basically the team has completed the graduation thesis on time, grasped basic
knowledge about protection relays in GE - UTE electrical system and supporting
software for controlling and monitoring devices in GE - UTE room. Completed the
Module connected to relay for controlling and monitoring its operation via relay and
103

relay supporting software. When completed, the team realized the importance of relays
in protecting and monitoring devices in transmission and distribution electrical
systems.
In the process of doing the thesis, mistakes are inevitable, especially technical
terms when translating from English to Vietnamese will have errors. We sincerely
hope teachers and friends give comments to improve the thesis.
Once again, the team sincerely thanks the enthusiastic guidance and special
support from Dr. Le Trong Nghia and teachers at GE - UTE Center who helped the
team complete the thesis.
