多种燃料锅炉效率曲线的辨识方法

多种燃料锅炉的运行优化是钢铁联合企业节约能源的一个主要方法,但是这种锅炉的效率曲线的辨识却是一个复杂而困难的非线性最小二乘问题。借鉴大系统递阶算法的思想,本文提出了一种新的两级递阶辨识的算法。这种算法通过预估关联量,将非线性最小二乘问题转化为两级线性最小二乘问题。实验的结果证明:这种算法是一种有效的算法。

A METHOD OF IDENTIFICATION OF EFFICIENCY CURVES OF MULTI-FUEL BOILERS

The optimization of multi-fuel boiler operation can save a lot of energy in an in-tegrated iron and steel works.But the identification of efficiency curves of the boil-ers is a complicated and difficult nonlinear least-squares problem.Considering for ref-erence the hierarchical algorithm for large scale systems,we have developed here anew two-level hierarchical identification algorithm which can transform the nonlinearleast-squares problem into a two-level linear least-squares problem by interaction pre-diction approach.Simulation results have proved that this algorithm is a very efficientand useful tool.
