摘要

随着串联电容补偿输电的推广应用

中国电力系统面临着严峻的次同步谐振(SSR)问题。针对SSR问题

文中基于采用电流控制模式的统一潮流控制器(UPFC)

提出了一种UPFC附加阻尼控制抑制SSR的方法;首先选择了附加阻尼控制信号接入UPFC控制器的位置

然后设计了UPFC附加次同步阻尼控制器(SSDC)

并推导了其抑制系统SSR的机理

且所设计的SSDC采用了模态分离控制以达到抑制多模态SSR的目的。最后

综合利用复转矩系数和时域仿真的方法

对所设计的UPFC装置SSDC抑制SSR的有效性进行了分析和仿真。结果表明

所设计的SSDC在有效抑制SSR的同时

不会影响系统和UPFC装置的正常运行。

Abstract

With the widespread application of series compensated capacitors

the power systems are facing the severe problem of subsynchronous resonance(SSR)in China. To solve the SSR problem

a method of supplementary damping control for unified power flow controller(UPFC)is proposed based on the UPFC with current control mode. The positions of supplementary subsynchronous damping signal accessing to UPFC controller are chosen at first. The UPFC supplementary subsynchronous damping controller(SSDC)is designed

and the principle how to damp SSR is deduced as well. Besides

the mode-splitting control is used in the designed SSDC to mitigate the multi-modal SSR. Finally

the complex torque coefficient and time domain simulation are both performed to analyze and verify the effectiveness of damping SSR with the designed SSDC. Meanwhile

the simulation results also suggest that the designed SSDCs have none negative effect on the performance of UPFC and the system. This work is supported by State Grid Corporation of China(No. SGRI-DL-71-14-002).
