خلاصه مقاله:

The complete hardware design of a total transmission line protection of high voltage power system is a vital issue because of possessing the following features:
- High speed and high precision response to the fault occurrance due to the use of Linear Prediction Method.
- Multi-functional protection relays (Distance protection, Power swing blocking, etc.) residing all in a single hardware package (Integrated Relays).
- Flexibility and extendablity of system solely by the aid of software.
The intergrated protection system has been successfully developed, built and tested.
