摘要

重点研究了串联和并联补偿控制装置在改善运行工况特性和小信号稳定水平方面的应用。分析了长距离交流输电线路的稳态运行，确定了SVC、TCSC和发电机PSS在不同控制参数下的最大传输功率。在从零到浪涌阻抗负载的大范围工况下，对长距离输电线路的小信号稳定性进行了研究。同时考虑控制系统参数的同步协调，以保证最大的振荡阻尼。文中指出，控制补偿装置的应用和控制系统的正确调整，可以显著提高电力系统的稳定特性。

Improving Controllability of Flexible Transmission Lines With Series Compensation

This study is focused on application of controlled devices of series and shunt compensation to improve the characteristics of operating conditions and level of small-signal stability. Analysis of steady-state operations of long-distance AC transmission line with determination of the maximum transmitted power at various control parameters of SVC, TCSC and generator PSS is carried out. Investigation of small-signal stability of long-distance transmission line is performed in wide range of operating conditions from zero to surge impedance loading. Simultaneous coordination of control system parameters is proposed under consideration to ensure maximum oscillation damping. It is noted that application of controlled compensation devices and correct adjustment of control system make it possible to increase the stability characteristics of the power system significantly.
