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
