Abstract

The invention belongs to the technical field of automatic power generation control of a unit and provides a method for realizing a frequency modulation function of a gas-steam combined cycle unit. The method comprises the following steps of: advancing a frequency modulation implementation way of a gas turbine control system, adding a frequency modulation control logic in a steam turbine control system by ascending/descending an external reserved load interface so as to control a frequency modulation load of a gas turbine, and adding the frequency modulation function in the steam turbine control system, thereby realizing the modulation frequency function of the gas-steam combined cycle unit. The method can be used for meeting the requirements of related standards, providing valuable technical references for similar units and optimizing the frequency modulation performance of the gas-steam combined cycle unit, thus having high popularization and application values.

Description

technical field [0001] The invention belongs to the technical field of unit automatic power generation control, and in particular relates to a method for realizing the frequency regulation function of a gas-steam combined cycle unit. Background technique [0002] Faced with the pressure of increasingly tense energy and environmental protection, my country has gradually restricted the construction of traditional coal-fired power generation units, replacing them with clean and efficient power generation methods such as gas, wind energy and solar energy, among which gas-steam combined cycle units are vigorously constructed main types of units. Compared with traditional coal-fired power generation units, gas-steam combined cycle units have the advantages of fast speed and environmental protection. Nowadays, the proportion of power generation is increasing, and the frequency regulation performance of gas-steam combined cycle units plays an increasingly important role in grid frequ...
