| 摘要: |
| 静止同步补偿器(STATCOM)的主要功能是电压控制,通过在STATCOM加入稳定控制器,则可以阻尼系统功率振荡.在推导出带稳定控制的STATCOM动态方程后,用五阶状态方程描述STATCOM的动态特性.再利用系统状态方程的信息寻找能提高系统阻尼的STATCOM,进一步分析系统中有效的阻尼信号,设计多信号稳定控制器加于STATCOM中以增强系统阻尼.最后,给出一个算例进行验证,算例的特征值分析表明了多信号稳定控制器的有效性,算例的EMTDC时域分析所得的系统参数响应也同时证明了多信号稳定控制器的控制效果. |

| Abstract: |
| The main function of STATCOM is voltage control. Corporated with stabilizer,STATCOM damps system power oscillation. After the dynamic function of STATCOM with stabilizer is deduced, the dynamic characteristics of STATCOM are described with 5 -order state equations. With the information of state equations,the STATCOM,which can improve the damping level of power system, is determined. The effective damping signals are further analyzed and a multi -signal stabilizer is designed. With a simulation example,the effectiveness of the designed multi -signal stabilizer is verified by the Eigenvalue analysis,as well as by the time -domain analysis of EMTDC. |
