Abstract

The invention belongs to the technical field of automatic control of thermal power generating units, and particular relates to a frequency and peak load modulation all condition coordination control method of heat supply unit. The method is used for automatic control during power grid frequency and peak load modulation under various conditions of the heat supply unit, and main parameters are automatically controlled in a reasonable range while rapid and stable responding of frequency and peak load modulation of the unit is guaranteed. Particularly, the power grid frequency and peak load modulation requirements of the heat supply unit under various conditions are automatically met by optimizing control logic of a DSC (distributed control system) of the heat supply unit. Coordination control stability and accuracy while the unit participates in frequency and peak load modulation and main steam pressure control stability and accuracy under various operation conditions of the heat supply unit are guaranteed, the equipment potential is fully developed, and the stability of main parameters is guaranteed while the power grid frequency and peak load modulation requirements are met. The labor intensity of an operator is reduced effectively, the control effect doesn't rely on the technical level of the operator, the real time performance is good, the site commissioning process is simple, and a project can be realized favorably.

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 ...
