Abstract

The present invention discloses a method and system for a thermal generator set load speed changing regulation control based on a regional new energy real-time generation load. A thermal generator set load speed changing regulation control switching threshold is set according to the new energy generation capacity and the power grid operation demand in a region, and when the new energy generation load in the region is larger than the threshold, a related thermal generator set automatically completes undisturbed switching of load regulation from low-speed regulation to high-speed regulation; and when the new energy generation load in the region is smaller than the threshold, the related thermal generator set automatically completes the undisturbed switching of the load regulation from high-speed regulation to low-speed regulation. The power grid regulation capacity is enhanced, the power grid power supply quality is improved, and the capacity of the stable operation of the power grid is improved.

Description

Technical field [0001] The invention relates to a thermal power generating set load speed adjustment control method and system based on the 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 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 generation load in the regional power grid is close to or Exceeding the capacity of thermal power generating units, the structure of the power grid has undergone significant changes. The load of new energy power generation is limited by natural conditions, its randomness is relatively large, and the frequency and peak shaving capacity of new energy power generation is relatively poor. Therefore, under the principle of not abandoning wind and solar power and fully consuming new energy power generation, power...
