| Abstract: | This paper introduces the SSE520 type frequency-voltage emergency control relay,which based on single chip microcomputer.According to the power shortage of the system,it can shed load as fast as the drop of the frequency and voltage,and the amount of the load shedding can keep pace with the development of the power shortage.This paper puts emphasis upon the procession of the control and execution of the frequency-voltage control relay,and mentions the precept of the output of the signals. |
