Abstract: Aiming at the problems of dynamic response time detection and harmonic suppression or filtering function verification in the two key tests of reactive power compensation device, the methods, equipment, waveform diagram and test data of the experiment for dynamic response time detection test and harmonic suppression or filtering function verification were studied,a comprehensive detection device and control method was proposed to meet the requirements of test. The dynamic response time of reactive power compensation device and the verification of harmonic suppression or filtering function were satisfied.The load current was realized by digital inverter by programming,and the energy feedback technology was used to save energy loss. The results indicate that the device can load current generation and has the advantage of voltage stability,small harmonics,flexible regulation of voltage and frequency.
Key words: reactive power compensation; dynamic response; suppression of harmonics or filtering
