Abstract

The invention discloses an electric power quality detection system of a power electronic transformer and relates to electric power quality detection of a power grid. The electric power quality detection system comprises the power electronic transformer (PET), a power electronic load (PEL) and a background control system. With the adoption of the detection system disclosed by the invention, output characteristics of the power electronic transformers with different technical optimized schemes and different control strategies can be detected, and particularly output electric power quality parameters can be detected; and the problem of output electric power quality detection of the power electronic transformer can be effectively solved and the product yield of the power electronic transformer is improved.

Description

technical field [0001] The invention relates to a power quality detection system, in particular to a power quality detection system for an electronic power transformer. Background technique [0002] In recent years, with the development of high-power electronic components and their control technology, a new type of transformer-electronic power transformer PET (Power Electronic Transformer), which realizes voltage conversion and energy transfer in power systems through electronic power conversion technology, is increasingly used Applied to power systems, compared with traditional power transformers, electronic power transformers have the advantages of small size, light weight, small no-load loss, and no need for insulating oil. At the same time, it can also play the role of power quality controller, and it is a new type of transformer with multiple functions. [0003] After an electronic power transformer is produced, in addition to the routine test, the current test of the ...
