摘要
Protective relay apparatus for developing signals responsive to subsynchronous current oscillations in a three-phase electrical power system, and for analyzing the signals to determine when corrective action is necessary. The positive sequence component of a subsynchronous current oscillation is developed via a summing arrangement, which eliminates the need for sequence filters. The positive sequence component of a subsynchronous current oscillation is processed to determine if it is an electrical transient which would shock the mechanical system of a turbine generator, or machine, to be protected, into mechanical resonance. It is also processed to determine if it is due to a growing mechanical oscillation of a turbine generator, such as might be initiated by a change in a parameter related to the turbine generator.
