摘要
提出了一种基于快速独立成分分析和支持向量回归的架空和电缆混合配电网的线损估算方法。这种方法以混合馈线所含架空线长度、电缆线长度、馈线首端的有功和无功为特征参数,估计配电网的线损值。采用快速独立成分分析提取特征参数的独立成分,以特征参数的独立成分和线损值为支持向量回归的输入和输出,建立混合馈线的线损估算关系。实测数据的仿真结果表明,所提出的架空和电缆混合馈线的线损估算方法准确、有效、可行。
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.
