Abstract:

Domestically-developed distributed control system （DCS） was firstly used in 1 000 MW ultra-supercritical units in Shenhua GuoHua Xuzhou Power Plant, which applied chimney-tower integrated technology. With the DCS system the integration control of unit and FGD island have been realized. Based on the construction project in Shenhua GuoHua Xuzhou Power Plant, the main technical features, network structure, configuration, and implementation are introduced in practical engineering of the domestically-developed EDPF-NT+ DCS, which could further provide references for the control system design of similar units.

Key words: 1 000 MW ultra-supercritical units, distributed control system （DCS）, EDPF-NT+, distributed processing unit（DPU）
