Mixed gas transformation method and system taking SF6 carbon peak reaching as target

The invention discloses a mixed gas transformation method and system with SF6 carbon reaching peak as a target, and the method comprises the steps: constructing an SF6 gas usage amount model, and predicting the future SF6 gas usage amount; calculating parameters in the SF6 gas usage amount model; the SF6 usage amount is reduced through SF6/N2 mixed gas transformation, the usage amount reduction amount needing to be completed every year is calculated, and according to the reduction amount, the transformation amount at least needing to be completed every year from the (n + 1) th year if the SF6 usage amount reaches the peak in the (n + m) th year is calculated; the method has the advantages that the demand planning of mixed gas transformation is realized, and the goal of carbon peak reaching is realized. 本发明公开了一种以SF6碳达峰为目标的混合气体改造方法及系统，方法包括：构建SF6气体使用量模型，预测未来的SF6气体使用量；计算SF6气体使用量模型中的参数；通过SF6/N2混合气体改造降低SF6使用量，计算每年需完成的使用量减少量，根据该减少量，计算若需在第n+m年完成SF6使用量达峰，从第n+1年起，每年至少应完成的改造量；本发明的优点在于：实现混合气体改造的需求规划，实现碳达峰的目标。
