Description

Technical Field

[0001] The utility model relates to the technical field of primary frequency modulation control, in particular to a primary frequency modulation control system of a thermal power plant. Background Art

[0002] Thermal power generation is a power generation method that uses the heat energy generated by the combustion of combustibles to convert water into steam, convert the kinetic energy of the steam through a steam turbine, and finally convert the kinetic energy into electrical energy through a generator connected to the steam turbine. During thermal power generation, the steam generated by the boiler will first enter the main steam main pipe, and then pass into the steam turbine. After passing through the steam turbine, the steam with pressure attenuation will pass into the heating main pipe, which is connected to the pipelines of each user to form a heat network, so as to reuse the steam and improve the utilization rate of resources and energy. During the power generation process, the frequency of the power grid may deviate, resulting in unstable output of the power grid, affecting the quality of electricity use, and may also cause safety hazards. Therefore, it is necessary to correct the frequency of the power grid through a frequency modulation to restore it to normal.

[0003] In the prior art, most primary frequency modulation control systems have fixed device bodies that cannot be rotated in direction and angle, which may require workers to take additional measures to adjust their positions during operation, increasing the complexity and inconvenience of operation. This may affect work efficiency, increase the labor intensity of workers, and reduce their comfort level.
