| Yungang Power Plant 220MW paper analyzes the operating characteristics of units and Unit coordinated control system characteristics of the controlled object. Improved control strategy for coordinated control system, Effectively improve the stability of the unit's operating capacity and load response, But also to achieve control and AGC units to meet the commercial operation of power system provides the premise and guarantee. Optimized coordinated control system, with manual, machine basic, basic and machine furnace four coordinated manner Boiler, With local, in the way of adjusting instruction to set the two load, Constant pressure and sliding pressure with the pressure setting of two ways, also has a load lock, forcing the L / landing, RB, AGC function. After the operation in recent months show that the optimal coordinated control system with complete functions, easy operation, safety and economic characteristics. The overall level of Habitat domestic advanced level of similar units, a model has acertain. Effectively improve the automation level of 220MW unit, the control unit for the 220MW accumulated valuable experience. |
