Description

technical field [0001] The invention relates to the field of electrical information technology, in particular to a method for optimizing power generation and reducing carbon dioxide emission on an ocean platform. Background technique [0002] Traditional offshore platform power generation usually only considers the input of a single fuel such as natural gas (or diesel) to the gas turbine for power generation, and emits carbon dioxide corresponding to the load. Improving its energy utilization efficiency includes two aspects: increasing the calorific value of the input natural gas and improving the power generation efficiency of the gas turbine. However, once the power conversion efficiency of gas turbines is increased to a certain value, it is very difficult to further improve it; at the same time, traditional power generation methods do not take into account the constraints of carbon dioxide, an important greenhouse gas. Under the situation of urgent changes in the economi...

Problems solved by technology

Although the method of exergy analysis can evaluate the energy efficiency well from the point of view of matter, but because the physical process of the reaction is fuzzy and irreversible, it is difficult to make the calculation process clear, so it is difficult to improve the efficiency of this analysis method.

Relatively speaking, although the calculation equation established according to the first law of thermodynamics can calculate the energy efficiency of the system more accurately, it cannot restrict the direction of energy flow
