摘要:

摘要:发电厂厂用电系统中越来越多采用电子开关型设备,不可避免的引入谐波污染。综合考虑发电厂中4种电子开关型谐波源,分别对其进行了理论研究与仿真分析,并通过对某发电厂6kV厂用电母线进行整体仿真分析谐波源对母线的影响。结果表明,一般情况下厂用电谐波源由于容量较小且多具备自身滤波措施,不会对母线产生较大影响。实际测量结果验证了理论与仿真的正确性。

Abstract:With more and more electronic switches were applied in plant auxiliary power system, harmonic pollution was inevitably produced. Took four kinds of electronic switch type harmonic source into consideration, theoretical research and simulation analyze was taken. The effect of harmonic source to busbar was simulating analyzed based on a power plant’s 6kV plant auxiliary power system. The result indicated that due to small capacity and selffiltering, harmonic source will not affect busbar.Test verify proved the theory and simulation.
