Abstract

The main aim of the paper is to analyze the performance of multilayer feed forward network ( MFFN) based SSSC on power handling capacity of the line, improvement in transient stability and damping of oscillations of the single machine infinite bus system (SMIB). This paper presents the comparative performance studies of two different controllers namely: [i] conventional PI controller, and [ii] multilayer feed forward network (MFFN) . Controllers are designed to coordinate two control inputs: in-phase voltage and the qudrature voltage of SSSC. The coordinated action of proposed SSSC controllers with power oscillations damping (POD) control & power system stabilizer (PSS) are tested for dynamic performance of the system under various system conditions. The simulation results shows that the proposed controllers increases the power handling capacity of the line, significant improvement in transient stability of the system, and damping of oscillations. The results indicates that the coordinated POD & PSS action further improves the dynamic performance of the system. The proposed SSSC controllers are tested in multi-machine system. The MFFN based SSSC controller provides superior dynamic performance than PI controller.

基于MFFN的静态同步串联补偿器(SSSC)的暂态稳定性改进

本文的主要目的是分析基于多层前馈网络(MFFN)的SSSC在线路的功率处理能力、提高单机无限母线系统(SMIB)的暂态稳定性和抑制振荡方面的性能。本文介绍了两种不同控制器的性能比较研究，即:[i]传统PI控制器和[ii]多层前馈网络(MFFN)。控制器被设计为协调两个控制输入:同相电压和SSSC的温度电压。采用功率振荡阻尼(POD)控制和电力系统稳定器(PSS)控制的SSSC控制器在不同系统条件下的协调作用进行了系统动态性能测试。仿真结果表明，所提出的控制器提高了线路的功率处理能力，显著改善了系统的暂态稳定性和振荡阻尼。结果表明，POD与PSS的协同作用进一步提高了系统的动态性能。所提出的SSSC控制器在多机系统中进行了测试。基于MFFN的SSSC控制器具有比PI控制器更好的动态性能。
