Embodiment Construction

[0033] The specific implementation of the coordinated control method for unitary units of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] The technical scheme of the present invention can be aimed at model predictive control (MPC) of unit units in thermal power plants, and is used to improve the load response speed of unit units and reduce steam pressure fluctuations. This technique is relevant to advanced process control (APC), in particular to model predictive control (MPC) of industrial processes.

[0035] The coordinated control method of the unit unit unit of the present invention mainly comprises the following steps:

[0036] Step S1: Advanced coordination controller C established in the host computer MPC , the advanced coordination controller C MPC Parallel connection with conventional coordinating controller CPID in DCS system.

[0037] Specifically, a device for predictive control of the coordinated co...

Abstract

The invention provides a coordination control method of a unit plant. The coordination control method of the unit plant comprises the steps that an advanced coordination controller CMPC connected with a normal coordination controller CPID in a DCS in parallel is established in an upper computer; a part closed loop test is carried out on a coordination control system under the state that the normal coordination controller CPID runs normally, model identification is carried out on a closed loop system with the output signals of the advanced coordination controller CMPC as input and with the output signals of the coordination control system as output, and the advanced coordination controller CMPC is put into the coordination control system to carry out running to carry out coordination control over the unit plant together with the normal coordination controller CPID; zero setting is carried out on the output of the upper computer when communication faults or upper computer system faults occur. According to the technical scheme, the coordination control method of the unit plant is suitable for model prediction control over coordination control over current electric power industry situations, the advantage that DCS control is high in reliability is maintained, high quality of model prediction control is introduced, and the control reliability of the coordination control system is improved.

Description

technical field [0001] The invention relates to the technical field of coordinated control of unit units, in particular to a method for coordinated control of unit units. Background technique [0002] Coordinated Control System (CCS), referred to as Coordinated Control System, is a comprehensive control of the boiler and steam turbine as a unit unit. The unit unit can generally be simplified as a controlled object with double input and double output. Refer to figure 1 as shown, figure 1 It is a simplified model block diagram of a unit unit. Simplified implementation conditions are as follows: [0003] (1) The air supply volume is adapted to the fuel volume to keep the combustion stable; [0004] (2) The induced air volume is adapted to the air supply volume to maintain the furnace pressure; [0005] (3) The amount of feed water is controlled by maintaining the water level of the steam drum, so that the feed water flow is balanced with the main steam flow; [0006] (4) T...
