Embodiment Construction
[0055] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0056] A coal quantity optimization predictive control method based on AGC optimization in a thermal power plant, including a feed-forward plus PID control strategy for the boiler master control in the AGC and CCS control systems, and, in order to improve the response speed and control accuracy of the boiler, also An intelligent feed-forward is added to design the coal quantity prediction link and plan the objective function. Through the DCS configuration programming of the power plant, the parameters can be automatically optimized, so that the feed-forward self-adaptation can be realized, the manual adjustment work can be reduced, and the main steam can be improved. The adjustment quality of pressure, and then improve the adjustment quality of CCS and AGC, such as figure 1 As shown, the intelligent feedforward of the present inventio...
