                  用戶要求采用機、爐、電集中控制,實現全廠輔網、主控一體化,便于統一管理。整個機組采用先進的分散控制系統對鍋爐、汽機、除氧給水、減溫減壓、空壓機房、循環水泵房進行監視、控制和保護。對于燃料,由于燃燒因子存在多變,控制系統應能很好的適應變異,從而獲得穩定連續的蒸汽生產??刂葡到y是生物質電廠實現高效生產的關鍵之一,要求整個系統具有高可用型的架構。 解決方案         生物質電廠采用了GE先進的PAC8000 DCS系統,并結合鍋爐蒸汽循環解決方案。整個系統功能包括數據采集(DAS)、模擬控制(MCS)、順序控制(SCS)、爐膛安全監控(FSSS)。每臺機組采用四對冗余控制器,系統采用高可用架構,控制器、網絡、電源等采用冗余技術。完成以下功能:         鍋爐-汽機協調控制;鍋爐輔機聯鎖及控制;鍋爐爐膛安全監督與控制;系統提供定壓或變壓運行方式,提供機組負荷管理,管理人員可遠程輸入機組負荷指令,提供燃料、風量交叉限幅控制,通過省煤器煙道中測得的含氧量校正鍋爐總風量。提供鍋爐汽包水位三沖量控制,單沖量和三沖量控制能夠無擾切換。 系統配備1個工程師站,7個操作員站,輔網和主控既分散又集中。先進的蒸汽循環解決方案,處理生物質燃料熱量因子變異的問題,燃料指令根據燃料的不同熱量進行自動校正T9431模塊備件產品重量 The user requires to adopt the centralized control of machine, boiler and electricity to realize the integration of auxiliary network and main control of the whole plant and facilitate unified management. The whole unit adopts advanced distributed control system to monitor, control and protect the boiler, steam turbine, deaerator feed water, temperature and pressure reduction, air compressor room and circulating water pump room. For fuel, the control system should be able to well adapt to the variation due to the variable combustion factors, so as to achieve stable and continuous steam production. The control system is one of the keys for biomass power plant to achieve efficient production. The whole system is required to have a highly available architecture. Solution biomass power plant adopts Ge advanced PAC8000 DCS system, combined with boiler steam cycle solution. The functions of the whole system include data acquisition (DAS), analog control (MCS), sequence control (SCS) and furnace safety monitoring (FSSS). Each unit adopts four pairs of redundant controllers, the system adopts high availability architecture, and the controller, network, power supply, etc. adopt redundancy technology. Complete the following functions: boiler turbine coordinated control; Boiler auxiliary equipment interlocking and control; Boiler furnace safety supervision and control; The system provides constant pressure or variable pressure operation mode and unit load management. The management personnel can remotely input the unit load command, provide cross limiting control of fuel and air volume, and correct the total air volume of the boiler through the oxygen content measured in the flue of the economizer. Three impulse control of boiler drum water level is provided, and single impulse and three impulse control can be switched undisturbed. The system is equipped with 1 engineer station and 7 operator stations. The auxiliary network and main control are both decentralized and centralized. Advanced steam cycle solution to deal with the variation of biomass fuel heat factor, and the fuel instruction is automatically corrected according to the different heat of the fuel
