国电宁夏石嘴山发电有限责任公司(简称石电公司)的厂级监控信息系统(SIS)与“全国燃煤示范电厂”基建工程同步建设、同步投入使用。石电公司SIS可根据自动发电控制(AGC)下达的全厂负荷指令、各机组的实时煤耗率曲线、全厂各机组实时运行状态等条件进行优化计算,实现机组负荷的优化分配；并可依据锅炉、汽轮机和煤耗的优化曲线提出优化操作指导,使机组运行在最佳状况。该系统设计先进、结构合理、安全防护措施符合要求,系统整体性能指标达到了有关标准的要求。投入运行3a来,对指导发电设备运行和设备检修维护发挥了重要作用。介绍石电公司SIS的特点、总体结构及进行多台机组负荷管理和分配的情况。
State Power Ningxia Shizuishan Power Co., Ltd. (hereinafter referred to as the company) plant-level monitoring information system (SIS) and the “National Coal-fired Power Plant” infrastructure projects simultaneously, simultaneously put into use. The SIS of Shiye Electric Co., Ltd. optimizes and calculates the unit load according to the whole plant load command issued by AGC, the real-time coal consumption rate curve of each unit and the real-time operation status of all units in the plant. Boiler, steam turbine and coal consumption optimization curve proposed optimization of operational guidance, the unit running in the best condition. The system is advanced in design, reasonable in structure and safe and protective measures meet the requirements. The overall performance index of the system meets the requirements of relevant standards. Put into operation 3a to guide the operation of power generation equipment and equipment maintenance has played an important role. Introduce the characteristics of SIS, the overall structure and the load management and distribution of multiple units.
