摘要
阐述了高次谐波对石化电网发、供电系统的危害和造成的不良后果,通过对大庆石化公司热电厂6kV系统不同运行方式下谐波数据的测量,查找出电压高次谐波出现的原因,提出了消减系统高次谐波干扰的措施,保证了电力系统的可靠平稳运行。
The hazards and bad consequence caused by high subharmonic to petrochemical electrical network were expounded.The cause for the occurrence of voltage high subharmonic was identified by harmonic data measurement made to the 6 kV system of Daqing Chemical Company Thermal Power Plant under different operation modes,and measures for reducing disturbance of system high subharmonic was put forward,and thus the reliable and smooth operation of the power system is ensured.
