摘　　要：在科技高速发展的现代,电力用户对电力要求越来越高。由于电力电网中的变压器、电动机等感性负载产生感性无功,大量的开关器件导致电网中存在大量的谐波,给电网带来了极大的危害。为解决谐波和无功给电力电网带来的危害,采用FPGA与单片机相结合的数字化系统对谐波进行高速检测并生成抑制信号,控制IPM处在整流和逆变两种状态进行谐波抑制和无功补偿。With the rapid development of science and technology, users have need for electricity increasingly. As the transformer, electric motor in power grid can produce inductive toad and the power switching devices are placed to be in a lot of harmonics, these do great harm to the power grid. This paper uses FPGA and MCU for rapidly detecting harmonics, generating inhibitory signals and then controlling IPM in the rectifying and contravariant two states to suppress the harmonics and compensate the reactive power.
