电力系统间谐波检测方法现状与发展趋势
Current Status and Development Trend of Power System Harmonic Detection Method
As a special harmonic,inter-harmonics exist in the power system widely,and have impacts on the power quality seriously,so it is very important to measure the inter-harmonic exactly.Inter-harmonics have certain difficulties in the process of real-time detection as a result of its non-linear,randomness,distribution,instability and so on,so it is very important to choose the appropriate detection method.The source and hazards of the inter-harmonics in kinds of different frequency range were introduced firstly in this paper,and various methods of detect inter-harmonics were summarized particularly,meanwhile the advantages and disadvantages of these methods were discussed in detail for selecting appropriate method in testing process.Furthermore,both the deficiency of the existing methods were pointed out and the trend of the development of inter-harmonics was discussed in this paper.
