2、ow efficiency in using throttling governing in gas turbine power plant, in this study, the working principle, the regulating process and the matters needing attention of variable-frequency regulating speed technology incompressor were expounded and analysis was made onits energy efficiency. The oper
3、ation practice showed thatthe shaft power of the compressor could reduce by 20. 5% after the variable-frequency regulating speed technology was applied in the compressor, which presented significant energy-saving efficiency. It can be used as the reference for the energy-saving transformation for si
