| 摘 要： | 针对抑制由HVDC引起的次同步振荡问题,阐述了附加次同步振荡阻尼控制器(SSDC)抑制次同步振荡(SSO)的原理。对SSDC设计中的控制器结构、输入信号的选取、相位补偿和增益调整等方面进行了重点论述,分析了不同方案的优缺点。从工程应用的角度,提出了一种便于工程实现的SSDC设计方案。在此基础上,针对东北-华北联网的高岭背靠背换流站附近绥中发电机组的次同步振荡问题,设计了相应的SSDC。实时数字仿真(RTDS)和实际控制器的闭环试验验证了所设计的SSDC能有效地抑制SSO,并对HVDC的动态特性影响较小。

| Abstract: | Aiming at the SSR problem caused by HVDC,we analyzed the mechanism of mitigating SSO with SSDC,such as controller structure,signal selection,phase compensation and gain adjustment etc.,in the process of SSDC design,and discussed the advantages and disadvantages of each option.From the view of engineering,we also proposed a scheme of SSDC which was easily realized.Based on the proposed scheme,the SSDC for mitigating Suizhong generation SSO,which was close to Gaoling Back-to-Back Converter Station,was designe... |
