基于IGBT的一种新型柔性交流输电系统静止同步补偿装置

New Static Synchronization Compensation System of Flexible Alternating Current Transmission System Based on IGBT

传统的静止无功补偿装置存在诸多缺点,而采用最新型的高度通用的静止同步补偿器(SSC),可以满足新的电力市场需要。SSC是一种并联型无功补偿装置,能发出或吸收无功功率,以控制电力系统中的特定参数。通过对SSC的结构、原理、伏安特性以及优点进行分析,为该装置的应用提供技术支持。分析表明,所有FACTS装置对加强暂态稳定性的作用比高起始励磁系统好,SSC要比现行采用的SVC性能更好。

The traditional static idle work compensation system has many shortcomings,but the adoption of newest highly general static synchronous compensator （SSC） can satisfy the new electric power market requirements. SSC is a kind of parallel idle work compensation system. It can send out or absorb the reactive power to control the specific parameters in the electrical power system. Through analysis of the SSC structure,the principle,and the voltage-current characteristics as well as its merits,we can provide technical support for the application of this equipment. The analysis indicates that all FACTS installments can strengthen the stability of transient state and the effect is better than that of high initial field system,and the function of SSC is better than the current SVC.
