Harmonic Suppression of 220kV Gong Ping power station

摘要

The harmonic in 220kV Gong Ping power station is much higher above the standard because of the load of the electric railway traction substation. The measure of the harmonic suppression is put forwarded, that is reasonably choosing the design parameter of the capacitor-series reactance branch, so that the reactive power compensation and the suppression of the harmonic are both satisfied. Through calculation and analysis, the project is proved to be fit for suppersing the harmonic and satisfying the output of reactive power.
