660MW thermal power plant energy saving improvement control strategy

Abstract

Abstract:

To reduce steam turbine control valve throttle loss, steam distribution method was improved according to control valve flow characteristic test. After improvement, unit primary frequency modulation and automation generation control (AGC) responsiveness was weakened. To improve unit primary frequency modulation and AGC responsiveness, a technology that bring condensate water into primary frequency modulation and AGC was introduced. Unit capability of capacity variation was enhanced, and reduced control valve throttle loss. Energy saving operation was realized.

Key words:

steam turbine, control valve, throttle, condensate water, primary frequency modulation, automatic generation control, energy saving
