Intelligent coordinated control method for thermal power unit

The invention provides an intelligent coordinated control method for a thermal power unit, which comprises the following steps: carrying out intelligent coordinated control on the unit; carrying out intelligent feed water control on a once-through boiler; carrying out intelligent fast reverse variable load processing; and carrying out intelligent overshoot control, wherein the intelligent overshoot control comprises the intelligent overshoot control of the once-through boiler and the intelligent overshoot control of a drum boiler. By improving the traditional coordinated control, the intelligent coordinated control method for the thermal power unit can improve the variable load performance of the unit, better meet the variable load requirement of a power grid, improve the stability and the economy during the operation of the unit, reduce the variable load cost of the unit and better coordinate interests of a factory and the power grid.
