摘 要: | 建立了包含STATCOM的双机保护系统模型,详细分析了STATCOM在稳态和故障暂态情况下对线路保护产生的谐波影响。仿真结果表明,投入STATCOM会使保护安装处的电压、电流的谐波含量明显放大,并且谐波情况随着STATCOM的安装位置不同而不同,从而引起保护的误动作,严重影响电力系统的安全运行。

Analysis of harmonics and effect with STATCOM in the transmission line protection |

Abstract: | In this paper,A two-generator protect system model with STATCOM is installed.And it detailed analyze the effects of harmonics from STACOM to the line protection in steady and transient state.The results show that inputting STATCOM will large the harmonics of voltage and current,which measured from the location of protection.What's more,the different positions of STATCOM will have different harmonics effect to the line protection.Words from upward can cause the protection false tripping.What the worse,it can seriously affect the normal operation of the power system. |
