Abstract

The invention belongs to the technical field of automatic control of thermal power generating units, and in particular relates to a coordinated control method for frequency modulation and peak regulation of heating units in all working conditions. It is used for the automatic control of the heating unit participating in frequency regulation and peak regulation of the power grid under various working conditions, ensuring that the unit can automatically control the main parameters within a reasonable range while responding quickly and stably to frequency regulation and peak regulation. Specifically, by optimizing the control logic of the distributed control system (DCS) of the heating unit, the heating unit can automatically meet the requirements of frequency regulation and peak regulation of the power grid under various working conditions. Ensure the stability and accuracy of the coordinated control of the unit when participating in frequency regulation and peak regulation and the stability and accuracy of the main steam pressure control of the heating unit under different operating conditions, give full play to the potential of the equipment, and meet the requirements of power grid frequency regulation and peak regulation at the same time , to ensure the stability of the main parameters. It effectively reduces the labor intensity of the operators, and the control effect does not depend on the technical level of the operators. It has good real-time performance, and the on-site debugging process is simple, which is convenient for engineering realization.

Description

technical field [0001] The invention belongs to the technical field of automatic control of thermal power generating units, and in particular relates to a coordinated control method for frequency modulation and peak regulation of heating units in all working conditions. It can be used for automatic control of heating units participating in power grid frequency regulation and peak regulation under various working conditions, ensuring that the unit can automatically control the main parameters within a reasonable range while responding quickly and stably to frequency regulation and peak regulation. Background technique [0002] Frequency modulation and peak regulation is an important means for power grid companies to maintain grid frequency stability. For the safety, stability and economical operation of the power grid and to improve the quality of power supply, the power grid company requires that the on-grid thermal power generating units must have the function of frequency ...
