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。
When a small system is in on-load operation in the early stage of black start, unit paralleling may fail due to reverse power protection.
黑启动初始阶段，小系统空载运行的情况下，由于逆功率保护而往往发生机组并车失败问题。
Now, supercritical or super-supercritical firepower generator units are constructed in many places, in order to reverse power tense situation promptly.
现在很多地方均在建设超临界或超超临界的大型燃煤火力发电机组，以便迅速扭转电力紧张局面。
If one set stops and reverse power protection is not provided, the set still running will drive the set that has stopped. The generator on the set that has stopped will act as a motor.
如果一台发电机组没有运转，并且没有逆功率继电器保护，运转的机组就会驱动这个机组，这台机组上的发电机则变成电动机运行。
