Automatic control and other means to achieve power generation and load demand power balance. In the event of an accident, the balance can not be controlled by these means
High frequency means high frequency, the rated frequency of the power system is 50Hz, the maximum range of 49.8~50.2Hz, under normal circumstances, the power dispatching department will be developed through the power generation plan
That response to the power parameters is high frequency, this requires high cycle splitting device, tripping the corresponding circuit breaker, to remove the part of power grid connected or separated from the original into two or more power, get rid of the accident or the narrow scope of the accident to
