Learning outcomes: • knowledge of purpose, functions and properties of devices of relay protection of elements of electric power grid - transmissions lines , transformers, autotransformers, bus and capacitor bank; • knowledge of methods of construction of relay protection devices, basic principles of their implementation; • knowledge of the practical methods of testing and checking individual relay protection devices; • ability to select relay protection devices for the elements of electric power grid; • ability to calculate of operating parameters of the relay protection devices of electric power grid; • ability to check the relay equipment.
Required prior and related subjects: • Plants and substations electric part, • Electric Grid, • Electromagnetic Transients, • Basics of Power System Relay Protection and Automation of power systems.
Summary of the subject: Protection of transmissions lines above 1 kV. Protecting of transmissions lines of ungrounded or offset neutral grid from single-phase earth faults. Remote protection of transmissions lines. Differential protections of transmissions lines. Transmission line protections with high frequency channels or radio channels (high frequency line protections). Protection of transformers and autotransformers. Ttransformer-feeder protection. Capacitor bank protection. Bus protection.
Assessment methods and criteria: • written reports on laboratory and calculation works, oral questioning (30%) • final control - exam: written and oral form (70%)
