Testing Technology of Multi-harmonic Characteristic Parameters and Its Application for UHVDC Dry-type Smoothing Reactors
摘要
Abstract
The various harmonic characteristic parameters have direct relation with the safety and stability of ultra-high voltage direct current (UHVDC) dry-type smoothing reactors.In order to determine the various harmonic characteristic parameters and estimate the performance of its operating conditions accurately,we put forward theoretical analysis and simulation results.The equivalent measuring principle in low current is verified and the current harmonic spectrum of UHVDC dry-type smoothing reactors under the double 12 pulse converter operating conditions are obtained.Then the measurement system and calculation process of the harmonic characteristic parameters are provided in this paper,and the characteristic parameters of a ±800 kV dry-type smoothing reactor are measured.The results show that,when power factor accuracy is 0.05％,and both voltage and current accuracy are 0.03％,the uncertainty of harmonic reactance test result is 0.11％ calculatedat 95％ confidence level.The measurement system proposed in this paper can be used to measure characteric parameters of dry-type smoothing reactor accurately.All ressearch results are benificial for the product design,performance test,and evaluation on UHVDC dry-type smoothing reactor.关键词
