摘要/Abstract

摘要： 当实际输电线路长度不足半波长时,需要通过人工调谐补偿。调谐网络类型需要详细论证。针对3种调谐网络,首先探索其分别适用于何种补偿方式;其次探讨适合于各调谐网络的安装和分布形式;最后对比各调谐线路过电压情况。研究表明：电容型在分散式补偿时无功过剩,PI型和T型在分散式安装方式下的过电压水平要高于集中式,线路侧补偿时的过电压水平较低。即电容型适宜采用分散式;PI型和T型调谐网络更适宜采用集中式;3种调谐网络中适宜采用安装在线路侧的集中式安置。

Abstract: When the actual length of transmission line is less than the half wavelength, the manual tuned compensation is needed. However, detailed analysis is needed to determine the appropriate tuned network types. Firstly, based on the existing three types of tuned networks, their respective suitable modes for compensation are investigated. In addition, the installation and distribution mode suitable for each tuned network is discussed. Finally, the overvoltage of each tuned transmission lines is comparatively analyzed. The results show that the reactive power is surplus when distributed compensation is used for capacitor-type tuned network; For PI and T type, the overvoltage level under distributed installation is higher than that under centralized mode, and the overvoltage level is low when line side compensation is used. Therefore, it can be concluded that the C type tuned network is suitable for the distributed compensation, while the PI and T type tuned networks are more suitable for centralized compensation; the three types of tuned networks are suitable for centralized installation on the line side.

Key words: half-wave-length AC transmission, tuned network, compensation mode, installation position, distribution mode, overvoltage
