The thyristor-controlled series capacitors (TCSC), one of the FACTS (Flexible AC Transmission Systems) controllers, are expected to provide better use of existing transmission facilities, such as flexible control of power flow, stability improvement, and an increase of power transfer capability. However, there has been little operating experience and thus further understanding of the operation and characteristics of TCSC is still to be sought. This study focuses on the following two subjects : (1) stability improvement and (2) optimal operation of TCSC for maximum use of transmission under open access era.Results obtained in this study are summarized as follows :(1) Power system stabilization by TCSC.Simulation using TCSC mathematical model have been conducted on power system stabilization by controlling the firing angle of TCSC. The study system is a one-machine connected to an infinite-bus system. Interaction between TCSC control and the existing power system controller such as AVR h … More as been investigated. It was found that without coordinate control of TCSC and AVR there has been less damping in the system. It has been made clear that individual control of three-phase firing angles of TCSC is effective for unsymmetrical line faults. Effects of additional resistor to TCSC circuit upon stabilization have been also discussed.(2) Application of PSO to power flow control for maximum acceptance of requested wheeled power.Open access to power transmission networks has been carried out to foster generation competition and customer choice. When several PPSs request to simultaneously supply power to customers, it is expected that transmission network accepts as much requested power as possible. It is possible to maximize total requested power by controlling power flow using TCSC. In this study, an algorithm based on Particle Swarm Optimization (PSO) has been proposed to determine the optimal reactance of TCSC. The validity of the proposed method has been checked successfully for 6 and IEEE 30 bus system models. Less

晶闸管控制串联电容器（TCSC）是柔性交流输电系统（FACTS）控制器之一，有望更好地利用现有的输电设施，如灵活控制潮流、改善稳定性和增加电力传输能力。然而，由于我国在这方面的操作经验较少，对TCSC的操作和特点还有待进一步的了解。本文主要研究两个主题：(1)开放接入时代下TCSC的稳定性提高和(2)TCSC的优化运行以最大限度地利用传输。本文的研究结果总结如下：(1)TCSC对电力系统的稳定作用。利用TCSC数学模型对控制TCSC发射角实现电力系统稳定进行了仿真。学习系统是一台连接到无限总线系统的机器。TCSC控制与现有电力系统控制器（如AVR控制器）之间的相互作用已被进一步研究。研究发现，在不进行TCSC和AVR协调控制的情况下，系统的阻尼较小。研究表明，单独控制三相点火角是解决非对称线路故障的有效方法。文中还讨论了附加电阻对TCSC电路稳定化的影响。(2)将粒子群算法应用于功率流控制，实现轮式功率的最大接收要求。开放接入输电网，促进发电竞争和用户选择。当多个pps请求同时向用户供电时，期望输电网能够接受尽可能多的电力请求。通过使用TCSC控制功率流，可以最大限度地提高总请求功率。本文提出了一种基于粒子群优化算法（PSO）确定TCSC最优电抗的算法。在ieee30和ieee30总线系统模型中验证了该方法的有效性。少
