Description

Technical Field

[0001] The present invention relates to the technical field of regional power energy structure rationality analysis. Specifically, it relates to a method for analyzing the rationality of regional power energy structure. Background Technique

[0002] As the cornerstone of the power industry, thermal power plants are widely used in the power industry due to their characteristics such as stable power supply, little geographical location limitation, and low construction cost. With the success of thermal power plant engineering construction, the rationality of regional thermal power energy structure analysis becomes particularly important. Therefore, it is necessary to analyze the rationality of the construction of regional thermal power energy.

[0003] When currently analyzing the construction of regional thermal power energy, it is usually through monitoring and analyzing the power generation and resource consumption corresponding to each thermal power energy construction station in the region, ignoring the analysis of the geographical environment and pollution status corresponding to the thermal power energy construction stations in the region. This not only greatly reduces the accuracy of the rationality analysis results corresponding to the thermal energy construction stations in the region, but also fails to ensure the persuasiveness of the rationality analysis results corresponding to the thermal energy construction stations in the region.

[0004] When currently analyzing the construction of regional thermal power energy, the analysis of the rationality of the distribution status corresponding to each thermal power energy construction station in the region is ignored, reducing the reliability of the rationality analysis results corresponding to the distribution of thermal power energy construction stations in the region, thus affecting the reference and reliability of the overall rationality analysis results of thermal power energy construction stations in the region.

Thus, a pollution status parameter set of each monitoring time period in the corresponding monitoring cycle of each thermal power station in the specified area is constituted.

[0061] As a further improvement of the present invention, in step four, the pollution status evaluation index of each thermal power station in the corresponding monitoring cycle in the specified area is analyzed.
