The Application of Series Active Filter for Improvement of Power Quality in Networks of Oil Enterprises

Dependences of indicators of quality of electric energy on a configuration of the consecutive filter in the conditions of parameters of the feeding network and the connected loading of the enterprises of oil production which allow increasing efficiency of compensation of the highest harmonics in power supply systems of various configurations are revealed. A control system for a sequential active filter using phase transformations and variable frequency pulse-width modulation of IGBT control pulses has been developed. The analysis of the efficiency of correction of the level of non-sinusoidal voltage curves on the results of simulation of sequential active filter in the conditions of oil production.
