Analog Control System (369-HI-0-M-0-0-0) is a system that controls the boiler and turbine of a steam turbine generator unit as a whole. The boiler side MCS refers to the boiler main control system, boiler fuel control system, supply air control system, induced air control system, start-up separator water storage tank water level control system, and steam temperature control system; Machine side MCS refers to the deaerator pressure, water level regulation system, and condenser water level regulation system; Closed water tank water level regulation system; High and low pressure water level regulation system and auxiliary steam pressure regulation system, etc. MCS is responsible for the closed-loop automatic regulation of the main process variables of water, steam, coal, oil, air, and smoke systems in the production process, as well as the load control task of the entire unit steam turbine generator set.

The sequential control system (369-HI-0-M-0-0-0) divides some operations of a unit into several local control systems according to the thermal system or auxiliary mechanical equipment, and operates in a predetermined order to achieve the purpose of sequential control. The scope of sequential control on the furnace side includes: supply fan, induced draft fan, primary fan, air preheater, furnace soot blowing system, etc. The scope of the machine side sequential control system includes: turbine lubricating oil system, condensate pump, high pressure heater, deaerator, 369-HI-0-M-0-0-0, vacuum pump, shaft seal system, circulating water system, closed water system, steam pump, electric pump, internal cooling water system, sealing oil system, rubber ball cleaning system, etc.
