Problems solved by technology

[0004] However, when performing deep peak regulation of heating units for a combination of multiple heating modes, there are many peak regulation conditions, complex optimization indicators and constraints, and it is difficult to quantitatively evaluate comprehensively, and it is impossible to accurately know the plant-level intelligence of the peak regulation thermal power plant. Quantitative operation scheduling decision-making, the solution optimization problem is how to carry out high-precision modeling of the system under the existing evaluation index system, multi-evaluation index optimization, and how to measure the economy and environmental protection of the system at the engineering level, and use Its goal is to efficiently, quickly, scientifically and reasonably find an optimal heating multi-mode combination scheme that meets practical applications

Description

technical field [0001] The invention belongs to the technical field of intelligent heating, and in particular relates to a comprehensive evaluation method for the operation of a multi-unit multi-mode heating power plant based on fuzzy analysis. Background technique [0002] With the continuous advancement of the clean heating policy in the northern part of the country, large-scale cogeneration systems represented by coal-fired heating units and gas-fired combined cycle heating units have become the main heat source for large and medium-sized cities in northern my country. Heating has been replaced, and heating units have accounted for about 1 / 4 of the total installed capacity of thermal power units in my country. From the national clean heating policy, ultra-low emission combined heat and power is the preferred technology for "clean heating". From the perspective of energy structure, coal-fired combined heat and power is also a typical way of clean and efficient utilization o...
