摘要
随着电力电子技术的迅速发展,电力系统中出现了大量的非线性负荷,它们在吸收基波功率的同时,产生大量的谐波注入电力系统。电气化铁道牵引负荷就是电力系统中较大的非线性负荷,是电力系统最主要的谐波源之一。本文对宁夏电网电铁负荷发展及谐波和负序分量的测试过程进行了分析总结,对目前遍布宁夏电网的宝中、包兰电气化铁道中的15个电气化铁道牵引站进行了大量细致的测试工作,并对测试数据进行了统计分析,充分验证和掌握了电铁负荷对宁夏电网电能质量的影响情况。
Analyzes the development of electrified railway load in Ningxia Power Grid and the test process of harmonic wave and negative sequence component,does lots of test on 15 electrified railway traction substation among Bao-zhong and Bao-lan electrified railway which spread over Ningxia Power Grid, makes statistics analysis on test data, verifies and master the impaction of electrified railway load on the quality of electric energy in Ningxia Power Grid.
