The Review of Technology of Power Quality Disturbances Generator

To test the Electric equipment's immunity to voltage disturbances, a special power quality disturbances generator was needed. According to the principles of power quality disturbances generator, they were divided into the following types: the form of arbitrary waveform generator adds amplifier, the combination of transformers in series or parallel mode, regulating transformer tap position, thyristor controlled reactor, AC/DC/AC converter and the other traditional methods in this paper. This paper discusses the main technology characteristics of implementations in detail, describes different kinds of equipment using occasions, summarizes the advantages and disadvantages of all principles and points out the using prospect and promotion of all kinds generators in future.
