Description

Technical Field

[0001] The present invention relates to the technical field of feedwater regulation control, in particular to a control method and system for improving the feedwater regulation quality of a dual-process Russian-made thermal power unit. Background Art

[0002] The first phase unit of the power plant is a 550MW Russian-standard supercritical DC dual-process thermal power unit. The boiler is a single furnace, fully suspended, "T" type, and the boiler steam-water process is divided into two symmetrical processes on the left and right according to the horizontal center line of the boiler. The two processes are independent and have their own feed water and temperature control systems. Each process is divided into two symmetrical and non-adjustable flow channels in front and back according to the longitudinal center line. The media in the two flow channels are mixed regularly to eliminate thermal deviations. The feed water control strategy uses the boiler master control basic function and the average value of the outlet temperature of the dual-process separator to correct the feed water pump speed control public instruction, and then adjusts the opening of each feed water pump regulating valve according to the speed feedback of the A and B feed water pumps and the instruction deviation. The outlet temperature control of the two flow channel separators uses the average value of the two flow channel separator outlet temperatures as a common instruction and the actual temperature value through PID control to form a water supply flow instruction. The water supply flow instruction and the feedback deviation are corrected by the differential pressure before and after the regulating gate to control the RL057 and RL058 regulating actuators. By tracking and observing the unit operating parameters, it is found that when the dual-process thermal deviation of the original water supply control strategy is large, the adjustment process of the water supply control system is slow and the deviation cannot be eliminated in time, and even the single-process water supply flow reverse regulation phenomenon occurs, which seriously affects the safe and economical operation of the unit.

[0003] When the original water supply control strategy of the first-phase unit of the power plant has a large thermal deviation in the dual flow, the adjustment process of the water supply control system is slow, the deviation cannot be eliminated in time, and even the single-flow water supply flow reverse regulation problem occurs. This patent designs and optimizes the unit water supply control strategy, independently controls the outlet temperature of the two-flow separator, and quickly eliminates the slow automatic adjustment and reverse adjustment of the unit's dual-flow combustion thermal deviation through the RL057 and RL058 regulating gates.

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Example 1

[0032] Reference Figure 1 to Figure 6 , which is the first embodiment of the present invention, and provides a control method for improving the water supply regulation quality of a dual-flow Russian thermal power unit, including: collecting water supply data of a dual-flow Russian thermal power unit; designing and optimizing the outlet temperature control logic of the 1st and 2nd flow separators; optimizing the water supply instruction control logic of correcting the outlet temperature average of the dual-flow separator, and completing the parameter setting of the optimized water supply control strategy.

[0033] S1. Collect water supply data of dual-process Russian-made thermal power units.

[0034] The water supply data includes the total water supply flow, the pressure difference before and after the regulating gate, and the separator outlet temperature.

[0035] S2. Design and optimize the outlet temperature control logic of the separators of process 1 and process 2.

[0036] Process 1 refers to process 1 of a dual-process Russian-made thermal power unit, which is a circulation system consisting of an independent boiler, steam turbine and generator; process 2 refers to process 2 of a dual-process Russian-made thermal power unit. Similar to process 1, process 2 is also a circulation system consisting of a boiler, steam turbine and generator.

[0037] The water supply flow regulating gate of process 1 is controlled as a whole through the total water supply flow set value of process 1, the actual value of the total water supply flow of process 1, the total water supply flow set value of process 2 and the actual value of the total water supply flow of process 2.

[0038] Design and optimize the control logic of the outlet temperature of the separator of process 1, so that the feed water flow regulating gate RL057 of process 1 is no longer affected by the feed water flow of process 2, independently control the opening of the feed water flow regulating gate RL057 of process 1, and set the upper and lower limit parameters of the regulating gate opening to prevent excessive adjustment from causing dry burning and bursting of the water wall of process 1. The original feed water control process is as follows Figure 2 As shown, the optimized control SAMA is Figure 3 The flow rate regulating gate RL057 of the flow 1 is controlled by the set value of the outlet temperature of the flow 1 separator, the actual value of the outlet temperature of the flow 1 separator, the set value of the total flow rate of the flow 1, the actual value of the total flow rate of the flow 1 and the correction value of the flow rate of the flow 1.

The 2-process feedwater flow regulating gate RL058 is controlled by the 2-process separator outlet temperature set value, the 2-process separator outlet temperature actual value, the 2-process total feedwater flow set value, the 2-process total feedwater flow actual value and the 2-process feedwater flow correction value.

[0040] S3. Optimize the average value of the outlet temperature of the dual-channel separator to correct the water supply command control logic, and complete the parameter setting of the optimized water supply control strategy.

The original water supply control process is as follows Figure 4 , the optimized control SAMA is as follows Figure 5Design and optimize the control logic of water supply instruction for the average value of the outlet temperature of the dual-channel separator, and perform PID control through the total water supply flow set value, 1 process separator outlet temperature set value, 1 process separator outlet temperature actual value, 2 process separator outlet temperature set value, 2 process separator outlet temperature actual value, and total water supply flow. Combined with the total speed instruction obtained by the air pump A speed instruction and the air pump B speed instruction, PID control is performed again to obtain the pump common speed instruction, and the air pump A speed instruction, air pump B speed instruction and electric pump C speed instruction are feedback-regulated.

[0042] After the optimization, the parameters of the feedwater control strategy are adjusted to solve the problem that when the thermal deviation of the two processes of the original feedwater control strategy of the unit is large, the feedwater control system is slow to adjust, the deviation cannot be eliminated in time, and even the single process feedwater flow reverse regulation problem occurs, while improving the feedwater regulation quality of the unit.

[0045] The data acquisition module 100 is used to collect water supply data of dual-process Russian-made thermal power units.

[0046] The operation module 200 is used to design and optimize the outlet temperature control logic of the 1st and 2nd flow separators.
