Design of TCSC model and in EHV power grid based on current injection method

本文介绍了TCSC的基本原理和工作方式,提出了一种基于注入电流法的TCSC串补模型,有利于稳定计算和收敛。在此模型的基础上设计了基于能量函数法TCSC模糊逻辑控制器,该控制器能依据模糊规则自适应地对控制参数进行调节,具有较强的鲁棒性。给出了应用电科院7节点系统的仿真例算,说明了基于注入电流法的可控串补模型在超高压电网环境下的可行性。

The basic principle and working method are introduced in the paper, and a TCSC model based on the current injection method is present, which is propitious to constringency. And a fuzzy logic TCSC controller based on the energy function method is designed. With this controller the parameters can be adjusted robustly by the adaptive fuzz rules. Simulation results based on EPRI-7 system are presented to demonstrate the TCSC model based on the current injection method is feasible in the EHV power grid.
