| 中文摘要: |
| 高压直流输电系统中的换流器是一种电力电子装置，具有非线性特性，易受直流输电系统运行方式、换流变压器的联结组别、换流器单元接线方式等因素的影响，在工作过程中会产生不同类型的谐波，引发谐波不稳，严重危害电力系统的安全、优质、经济运行。因此，对换流器产生的谐波要进行准确分析，通过滤波装置的合理配置，有效处理谐波对供电系统、用户和周围电气环境造成的危害，才能保证高压直流输电系统的正常运行。 |
| 英文摘要: |
| The converter in a HVDC transmission system, an electronic power device with nonlinear characteristics which is susceptible to such factors as DC transmission system's operational mode, connection group and converter connection unit, may generate different types of harmonics, thus causing harmonic instability and seriously harming safe, high quality and economical operation of the power system. Therefore, harmonics produced by the inverter must be analyzed accurately. Normal operation of HVDC transmission systems can only be guaranteed when the filtering device is rationally allocated, and hazards in power supply systems, users and surrounding electrical environments caused by harmonics are treated effectively. |
