High voltage due to DG: High voltages may be caused by reverse power flow.
分布式发电系统引起的高电压：反向功率流可能引起高电压。
As a result, the generating action of the induction machine will cause the power flow to reverse and the kinetic energy of the drive system will be fed back to the supply.
结果，由于感应电动机为发电机，功率流将反向，拖动系统的动能将被反馈回电网。
Reverse power relay a reverse power relay is a relay with a wattmeter movement that senses the direction of power flow.
逆功率继电器逆功率继电器是指带瓦特计的继电器，用来感知电流的方向。
