ATSC dynamic reactive power compensation device and its effect on improving the power quality

摘要

A method of the thyristor rapid switched capacitors is presented in this paper, which breaks through the bondage of the conventional methods. In addition, a novel algorithm of two time reactive power has been presented, with which reactive power can be calculated fast. Meanwhile, with microcomputer synchronous phase lock technology, quick switching without transition can be realized, dynamic reactive compensation for impact load can be achieved, and the total response time is shorter than 16ms. This technology not only can compensate reactive current dynamically but also can improve the voltage waveform to a certain extent. In the end, the type test waveforms and the users' field test waveforms are given to show the validity and effectiveness of this technology. This method is an effective way to improve power quality.
