基于快速独立成分分析和支持向量回归的混合馈线线损估算
Loss estimation of power distribution systems based on fast independent component analysis and support vector regression
摘要
Abstract
This paper presents a new method for loss estimation of distribution systems comprising overhead lines and power cables. It is based on fast independent component analysis (Fast ICA) and support vector regression (SVR). In the method, the length of over-head lines, length of power cable, active and reactive powers entering the sending end of the feeder are taken as the input characteristic parameters to estimate the loss of distribution network. The Fast ICA is employed to extract the independent components of the input characteristic parameters. The independent component of characteristic parameter and power loss are taken as the input and output of SVR to build the loss estimation relation of hybrid feeder. The simulation result of actual measurements shows that the proposed method is accurate, valid, and feasible.关键词
