Abstract

The invention discloses a thermal power generating unit load variable speed adjustment control method and system based on regional new energy real-time power generation load. According to the new energy generation capacity in the region and the operation demand of the power grid, the switching threshold for thermal power generating unit load variable speed regulation is set. When the new energy power generation load in the area is greater than the threshold, the associated thermal power generation unit automatically completes the non-disruptive switching of load regulation from low-speed regulation to high-speed regulation; when the new energy power generation load in the area is smaller than the threshold, the associated The thermal power generation unit automatically completes the undisturbed switching of load regulation from high-speed regulation to low-speed regulation. The invention can enhance the regulation ability of the power grid, improve the power supply quality of the power grid, and enhance the stable operation ability of the power grid.

Description

technical field [0001] The invention relates to a variable-speed adjustment control method and system for a thermal power generating set based on real-time power generation load of regional new energy. Background technique [0002] With the rapid development of new energy power generation equipment technology, the proportion of new energy power generation load in the power grid is increasing, especially in areas rich in new energy such as wind power resources, the proportion of new energy power generation load in the regional power grid is close to or Exceeding the capacity of thermal power generation units, the composition and structure of the power grid has undergone significant changes. The load of new energy power generation is limited by natural conditions, its randomness is large, and the ability of frequency regulation and peak regulation of new energy power generation is relatively poor. The pressure of operation is increasing, and the impact on the quality of power...
