摘要在已有水质模型和部分水质监测点实测数据的基础上，根据最小二乘原理，建立了给水管网水质（以余氯为对象）工况复核模型，并用改进遗传算法对其求解。 - Finally , the method of estimating power customer emission level based on binary linear regression is put forward , which make it a condition that harmonic emission is steady at the point of common coupling . combined with power system thevenin equivalent and customer norton equivalent , according to the principle of least squares method , the voltage that a customer ' s harmonic current begets at the point of common coupling can be estimated in the light of the plural correlation of network parameters
最后，提出了基于二元线性回归的用户谐波发射水平估计方法，该方法在假设公共联接点谐波发射稳定的情况下，结合系统侧戴维南等值与用户侧诺顿等值的电路图，按照最小二乘法原理，利用电网各参数的复数关系推导关于系统侧谐波阻抗的二元线性回归方程，并根据谐波阻抗的估计值求取用户谐波电流在公共联四川大学硕士学位论文( 2003 )接点产生的电压降。
