The invention relates to the technical field of
electric power automation control, and discloses a coordinated
control system for a generator set, which adopts an intelligent DCS
integrated design architecture and performs real-
time data interaction with a set decentralized
control system through hard wiring or a communication protocol. According to the
system, through deep fusion of a
model prediction control algorithm and intelligent DCS
integrated design, a boiler-
steam turbine dynamic coordination model is constructed, and a control instruction is generated in real time in combination with a rolling optimization strategy. By means of the design, the main
steam pressure deviation is controlled within + / -0.2 MPa, and the load response rate reaches 1.5% Pe / s and is improved by more than 40% compared with a traditional
system. Particularly, under the working condition of deep peak regulation, by means of decoupling control over a fuel-air supply-
water supply loop through a neural network
algorithm, main
steam temperature fluctuation (within + / -5 DEG C) and reheater spray desuperheating water quantity sudden change (the change rate is smaller than or equal to 10 t / min) are effectively restrained, the
control quality of a unit under the conditions of variable loads and variable
coal quality is remarkably improved, and the control efficiency of the unit is improved. And the high-standard requirement of the
power grid on the AGC performance is met.
