摘要
随着我国电网向大机组、大电网、高电压和远距离输电发展,电力系统的稳定问题变得日益突出。为改善系统电压稳定和故障后系统的暂态稳定性,将两种动态补偿装置--静止无功补偿器(SVC)和静止同步补偿器(STATCOM)应用于电力系统中,以实时动态方式向系统提供无功补偿。利用MATLAB/SIMULINK平台建立了补偿系统仿真模型,验证了SVC、STATCOM对维持电力系统稳定性的作用,并对两者进行了比较,指出STATCOM具有更广阔的应用前景。
With the development of large unit,large power , high voltage and long - distance on the power system, the power system stability issues become increasingly prominent. Two new types of dynamic compensator of static var compensator（SVC） and static synchronous compensator （STATCOM） is used in the power system to im- prove voltage stability and transient stability after fault though providing real - time dynamic reactive power compen- sation. SVC and STATCOM maintaining the stability of the power system is verified through the MATLAB/SIMU- LINK building compensation system models. It is pointed out that STATCOM has a wide application prospect by comparison.
