摘　　要：针对矿井提升机负载给电网造成的无功冲击和高次谐波污染等危害,介绍了基于瞬时无功理论的动态无功补偿系统,并利用Matlab/Simulink软件进行建模仿真,分别在负载突变、三相不对称情况下补偿系统无功。结果表明,该静止无功补偿装置能够快速、准确地补偿系统无功功率,抑制系统谐波,维持系统的稳定。Contraposing the hazards of the reactive power impact and the harmonic pollution from the loads of mine hoist to the power grid, a dynamic reactive power compensation system is introduced based on the instantaneous reactive power theory. The model of this system is established and simulated with Matlab/Simulink. The reactive power of the system is compensated in the cases of the load changes and three phase unbalance. The results show that the static var compensator （SVC） can compensate the reactive power of system quickly and precisely, can suppress the harmonic of system and keep system stability.
