Integrated feeder protection

The paper presents the development of highly sophisticated numerical system for protection, measurement and control of the electric power system's (EPS) lines. The requirements to be fulfilled by the system are defined, and also the selection of the hardware base and necessary microcomputer's performance; structure of the realized hardware is given, together with the ambient for the program's development and also the results of the complete system's testing. The results obtained fully meet all requirements for the modern system of numeric protection.
