对福建首条高速电气化铁路温福线牵引用电谐波、负序、有功、无功等主要电能质量指标进行深入分析,认为高速电气化铁路采用交直交型电力机车比传统的交直型电力机车虽对电能有所改善,但仍存在谐波超标及无功倒送现象,给电网安全稳定经济运行带来隐患,应引起高度重视并积极解决。
The paper analyzes the main power quality indexes of harmonic, negative sequence, active power and reactive power of the first high-speed electrified railway in Fujian Province, and concludes that the high-speed electrified railway adopts the AC-DC type electric locomotive as compared with the traditional AC / DC electric locomotive However, there are still some problems such as excessive harmonics and reactive power transfer, which bring hidden dangers to the safe, stable and economic operation of the power grid. Therefore, it should be given high priority and actively solved.
