Abstract: Based on the analysis of the difficulties in the control of double-reheat power generation units, the development of the key technologies of the distributed control system(DCS) for 1 000-MW double reheat ultra-supercritical(DRUSC) power generation units is presented, which involves the design and technical characteristics of DCS, the key control strategies and technologies for the coordinated control system, the steam temperature, the bypass system and the automatic plant startup and shutdown(APS). The application on the demonstration project shows that the performance of DCS is stable and reliable with the major indices meeting or better than the designed values. The whole-process automatic control from starting up to shutting down has been realized.

Key words: coal-fired power generation, 1 000 MW, ultra-supercritical unit, double reheat cycle, distributed control system (DCS), turbine-boiler coordinated control system (CCS), steam temperature control, three-stage bypass control, auto plant startup and shutdown (APS), demenstration power plant
