摘要

随着输电线路负荷的不断增加,出现了电压不稳定和功率损耗增加的问题。本文研究了静态同步补偿器(STATCOM)在降低输电系统功率损耗和提高电压稳定性方面的作用。为了验证STATCOM在这方面的能力,在DIgSILENT PowerFactory v15上建立了IEEE 14总线测试系统的比例模型。采用Newton Raphson算法对系统中有无STATCOM两种情况下的潮流进行了研究,并给出了四种不同情况下的仿真结果。结果表明,系统弱母线的新电压分布得到了充分改善,在正常负荷下加入STATCOM后,系统有功和无功损耗分别降低了17.73%和24.80%。

Investigating the effect of Static Synchronous Compensator (STATCOM) for voltage enhancement and transmission line losses mitigation
There has been a problem of voltage instability and increased power loss on transmission lines due to the ever increasing load growth. This work investigates the effect of Static Synchronous Compensator (STATCOM) to mitigate power losses and enhance voltage stability of a transmission system. To validate the capacity of STATCOM in this direction, a scaled model of IEEE 14 bus test system was built on DIgSILENT PowerFactory v15. A power flow study using the Newton Raphson algorithms was adopted with and without STATCOM incorporated into the power system while considering four different scenarios, the simulation results are presented and discussed. It is noted that there was sufficient improvement in the new voltage profile obtained for the weak buses of the system, the active and reactive power losses was mitigated by 17.73% and 24.80% respectively when STATCOM was incorporated at normal load.
