asynchronous - (digital communication) pertaining to a transmission technique that does not require a common clock between the communicating devices; timing signals are derived from special characters in the data stream itself.
Subsynchronous resonance is a phenomenon in which the resonant frequency of the turbine generator shaft coincides with a natural resonant frequency of the electrical system such that there is a sustained, cyclic exchange of energy between the mechanical shaft and the electrical system.ubsynchronous resonance is a phenomenon in which the resonant frequency of the turbine generator shaft coincides with a natural resonant frequency of the electrical system such that there is a sustained, cyclic exchange of energy between the mechanical shaft and the electrical system.
