| Abstract: | The presence of harmonics serious threats the stability and reliability of the power system, having a certain impact on the safety operation of urban rail transit. The paper introduces the working principle of the 24-pulse rectifier set and the connection type of transformer, analyzes the harmonic characteristics. It describes the principles for active filter and harmonic current detecting methods, control algorithm. Finally, a simulation model is created to study the compensation function of the non-characteristic subharmonics of the active filter on the 24-pulse rectifier set. |
