Hydropower generators require protection against mechanical overloads, electrical faults and disturbances in excitation systems. Medium and low voltage hydro units often operate under varying load conditions, making precise supervision essential. Rapid detection of earth faults and differential faults ensures safe operation of turbines and generators, while protection functions such as ANSI81R df/dt (ROCOF) provide anti-islanding protection when the related part of the grid remains isolated due to upstream fault.
The SYMAP®Compact(+) product line offers a diversity of protection functions, communication protocols, high flexibility programming of PLC logic, and power plant controller (PPC) fulfilling various renewable source plant requirements.
