用户要求采用机、炉、电集中控制,实现全厂辅网、主控一体化,便于统一管理。整个机组采用先进的分散控制系统对锅炉、汽机、除氧给水、减温减压、空压机房、循环水泵房进行监视、控制和保护。对于燃料,由于燃烧因子存在多变,控制系统应能很好的适应变异,从而获得稳定连续的蒸汽生产。控制系统是生物质电厂实现高效生产的关键之一,要求整个系统具有高可用型的架构。 解决方案         生物质电厂采用了GE先进的PAC8000 DCS系统,并结合锅炉蒸汽循环解决方案。整个系统功能包括数据采集(DAS)、模拟控制(MCS)、顺序控制(SCS)、炉膛安全监控(FSSS)。每台机组采用四对冗余控制器,系统采用高可用架构,控制器、网络、电源等采用冗余技术。完成以下功能:         锅炉-汽机协调控制;锅炉辅机联锁及控制;锅炉炉膛安全监督与控制;系统提供定压或变压运行方式,提供机组负荷管理,管理人员可远程输入机组负荷指令,提供燃料、风量交叉限幅控制,通过省煤器烟道中测得的含氧量校正锅炉总风量。提供锅炉汽包水位三冲量控制,单冲量和三冲量控制能够无扰切换。 系统配备1个工程师站,7个操作员站,辅网和主控既分散又集中。先进的蒸汽循环解决方案,处理生物质燃料热量因子变异的问题,燃料指令根据燃料的不同热量进行自动校正T9402 -2模块备件产品重量 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
