巴慕达净化器在那修大型分布式电站

　　With the increase in the penetration rate of large distributed power stations such as photovoltaic, wind energy (10 kV ~ 35 kV),The interaction of harmonics generated by the distributed power station system consisting of multi-inverter is also more complicated.Harmonics of distributed power stations output exhibit high frequency, wide frequency domain.The figure shows the relationship between the typical distributed power station resonance amplification and harmonics, and the transmission distance.Harmonics in the process of transmission network propagation,Influence of distributed capacitance in transmission wires and background harmonic voltages,The resonance of current and voltage will occur.There are two kinds of governance programs to suppress the string parallel resonance problem of broadband harmonics in the transmission network.That is: change the transmission network parameters,The purpose of eliminating resonance 巴慕达加湿器售后服务 is achieved by a parallel reactor; installing high pressure mixed active filtering device.Reduce the harmonic current content flowing into the grid.
