Hydroelectric power stations

Protection and control for hydro generation

For hydropower plants SYMAP^® solutions cover generator unit protection and control, synchronization, grid decoupling, transformer protection, feeder protection, excitation and reactive power monitoring, communication with the supervisory system and event/fault recording.

For a single generation unit or a grid connection with Grid Code requirements, SYMAP^® Compact+ GC is considered for NA protection, EZA/PPC functions, synchronization, voltage and frequency monitoring and communication with the supervisory system. For hydro plants with multiple units, parallel operation, island operation, bus-tie logic or load sharing, the corresponding SYMAP^® BCG/ECG variants are considered for Power Management and coordination of generator groups.

Which SYMAP^® for this application?

For the grid connection of a single hydro unit with Grid Code requirements, SYMAP^® Compact+ GC is considered. For generator protection and control, the corresponding SYMAP^® G configuration is used, while for multiple units in parallel operation, load sharing, island mode and bus-tie logic, the SYMAP^® BCG/ECG variants are considered. For transformers, feeders, auxiliary motors, DC supplies and dedicated connections, the corresponding T, F, M, DC, D or LD variants are used according to the function in the scheme.
