Research of Scheme of Dynamic Reactive Power Compensation of Mine Hoist

  • Aiming at the problems of impact of reactive power and high-order harmonic wave pollution caused by mine hoist to power grid,the paper proposed a scheme of TSC type dynamic reactive power compensation of mine hoist taking characteristics of hoist load of one coal mine of Jiaozuo coal mine group as sample.It analyzed influence of mine hoist load on power grid and harmonic current produced by mine hoist load,and introduced design and implementation of the scheme in details.The simulation result showed that the scheme of TSC type dynamic reactive power compensation can satisfy the requests of dynamic compensation basically,and can enhance power factor of net side and reduce input of harmonic wave to high-voltage power grid as well as reduce distortion rate of harmonic voltage and harmonic current.
