电力线载波通道频率分割装置的优化设计

Optimization Design for Frequency Compensation Device of Power Line Carrier System

本文对电力线载波通道频率分割装置的电路、阻抗特性和同一母线不同线路之间的高频跨越衰耗的计算方法进行研究。在建立分析分割装置通频带内频谱特性目标函数的基础上,提出采用Nelder-Meal非线性优化法设计分割装置的方法。利用此方法对山西南社变电站的分割装置进行了优化设计,并与原设计进行比较,得出一些建设性的结论。

The paper studies the circuit and the impedance character of the compensation device and the calculation formula of the cross-station attenuation in a substation. By using the Nelder-Meal nonlinear programming algorithm and deriving the objective function optimizing the compensation device, the CAD software is developed for designing the optimization compensation device. The optimization design of the compensation device at the Nanshe substation (in Shanxi province) is shown as an example. By testing the analog circuit board and analysing the test data, some important conclusions achieved.
