摘要

在过去几年中，拉脱维亚的工业和家庭部门有所增长。工业和家庭部门主要在拉脱维亚首都里加附近发展。这导致了20kV电网的扩张，因此似乎有必要建立新的20kV电网。在人口密集地区新建20kV电缆网。此外，自2011年以来，位于人口稠密地区的现有架空线路将改为电缆线路。电缆长度的增加导致接地故障电容电流的增大。本文的主要目的是展示分布式补偿在拉脱维亚20kV电网中的应用。

Concepts and Practical Application for Distributed Compensation of Earth Fault Current in Latvia's 20 kV Networks

Over the last years industry and home sector has grown in Latvia. Industry and home sector developed mostly around Riga - capital of Latvia. This caused an expansion of the 20 kV networks therefore appear necessity to build new 20kV networks. The new 20kV network in densely populated areas is built as cable network. Besides since 2011 existing overhead lines which are located in densely populated areas is going to change to cable lines. Increasing of cable lengths brings increment of earth fault capacitive current. Main aim of this article is show distributed compensation application in Latvia's 20kV networks.
