摘 要: | 针对宁夏某石化公司离心式CO2压缩机透平转速预测难以实现问题,引入PSO-SVM回归模型对离心式压缩机透平转速进行预测.分析选取离心式压缩机透平转速作为模型因变量,通过相关分析从采集量中选取高相关度预测因子,运用粒子群算法选择模型最优参数,利用支持向量机的方法建立模型进行预测,与传统的SVM模型进行对比,该模型得到了良好效果,能够有效预测压缩机透平转速.

Abstract: | For problem of centrifugal CO2 compressor turbine speed prediction in Ningxia petrochemical company, PSO-SVM model was introduced to predict centrifugal C02 compressor turbine speed, centrifugal compressor turbine speed was selected as model's dependent variable , high relevance predicting factor was selected through correlation analysis from acquisition data, optimal parameters were selected by way of particle swarm optimization (PSO), forecast model was established on the basis method of support vector machine(SYM). Compared with normal SVM model, there are good effects for compressor turbine speed prediction. |
