超临界机组协调控制系统在崇信发电厂中的应用

摘要

针对崇信发电厂660MW超临界直流机组协调控制系统进行了分析，优化了机组协调控制方案。实践证明，投产后机组运行稳定，调节品质良好，在40％～100％MCR（额定负荷）段具有优良的负荷适应性，为大型超临界机组协调控制系统的设计提供了很好的借鉴。%The coordinated control system for 660 MW supercritical unit is analyzed ,it has been optimized during the commissioning of the unit .The practice result shows that the unit is stability and the regulating quality is excellent ,in the load range of 40% ~100% MCR ,the unit makes fine in the adaptability to the variety of load .This work provides a good reference for the design of the coordinated control system of large supercritical unit .
