Abstract

This work describes a secondary control scheme of a series reactive compensator for a power system based on a single voltage-source pulse-width-modulated (PWM) inverter. The controllable capacitive reactance can be used as a supplementary control variable for the secondary (external) controller (SC) of a series capacitive reactance compensator to improve the dynamic transient and damping performances of the power system. From the viewpoint of agent-based global dynamic optimization of a system, the selection and use of suitable input signals for the SC are investigated. Detailed simulation results show that the SC with local feedback loop (LFL) has a powerful control performance; however, it requires the controllable compensation for a reference change due to different operating conditions. On the other hand, the SC with global feedback loop (GFL) avoids the need of reference compensation; moreover, its dynamic control performance is improved when the dual inputs (frequency and active power signal) are used, compared to when only the frequency is used as an input signal.

基于电压源PWM逆变器的串联无功补偿器二次控制

本文介绍了一种基于单电压源脉宽调制（PWM）逆变器的电力系统串联无功补偿器的二次控制方案。可控容抗可用作串联容抗补偿器的二次（外部）控制器（SC）的补充控制变量，以改善电力系统的动态瞬态和阻尼性能。从基于agent的系统全局动态优化的角度，研究了SC输入信号的选择和使用。详细的仿真结果表明，具有局部反馈环（LFL）的SC具有强大的控制性能；然而，它需要对由于不同操作条件引起的参考变化进行可控补偿。另一方面，具有全局反馈环（GFL）的SC避免了参考补偿的需要；此外，当使用双输入（频率和有功功率信号）时，与仅使用频率作为输入信号时相比，其动态控制性能得到改善。
