中文摘要 | 在上都电厂4号机上进行了附加励磁阻尼控制(SEDC)提高次同步扭振阻尼的现场试验,介绍了试验的基本原理、运行环境、主要内容和试验数据分析。试验结果表明:采用励磁注入法可安全、可靠地激发轴系次同步扭振并精确测定其特征频率,SEDC能有效改善各扭振模态的阻尼且不会对励磁系统常规调节功能(自动电压调节器/电力系统稳定器)造成不利影响。作为中国第1次以现场试验方式实证SEDC提高次同步扭振模态阻尼的效果,为自主研发和应用SEDC抑制次同步振荡/谐振奠定了基础。; A field test was conducted on the number 4 turbine-generator at Shangdu Power Plant to validate the effectiveness of supplementary excitation damping control (SEDC) for torsional damping enhancement. The principle, operating-condition, procedures and results of the test are presented. The test results indicate that torsional oscillation can be successfully and safely excited by injecting subsynchronous signals into the generator exciter regulator, and that SEDC greatly improves the torsional damping without interfering the AVR/PSS function. This is the first time in China that a practical SEDC has been developed and its effectiveness in improving torsional damping has been verified in the real system. It represents an important step toward application of SEDC for the purpose of SSO/SSR mitigation in China. |
