Discussion on Operational Stability of Governor Turbine Hydraulic System Considering Effect of Power System

Hydropower has grown to play an important role in power systems including increasing clean and low-carbon energies, the effect of electric loads should be basically evaluated for reliable operation these systems. For hydraulic–mechanical–electrical system hydropower station, state equation model stability evaluation was derived with typical load models elastic pipe flow, after experimental confirmation a built single-unit setup system, effects different electrical flow on were investigated detail. The results indicate that characteristics, numerical consistent research, unit’s regulation performance dynamic superior static load. Evident differences existed operational stability, mainly depending length corresponding models, optimum-order preferred reveal interactions between Furthermore, two-unit potential coupling resonance is pointed out preferred-order flow.
