【Abstract】 A new solution of phase and frequency measurement for use with a hydro turbine governor is proposed. It uses Am9513A based Industrial PC card to measure two signals of unit frequency, one signal of power system frequency and the phase shift between them. Redundancy of unit frequency signals is beneficial for fault tolerance and improves the reliability of the governor. The hardware design and interrupt routine programming are also described.更多还原
