A System Level Low Power Static Real-Time Scheduling Algorithm of Mixed Tasks and Its Application to FTU

FTU (feeder terminal unit) is an important device of distribution automation system, always working in bad environment. Its power dissipation and related thermal issues affect the lifetime of circuit component. When blackout in power grid comes forth, FTU will be working normally powered by the battery. Reducing the power of FTU can increase the normally working time and then increase the power grid's reliability. Traditionally, studies on energy reduction techniques of FTU have been conducted in the circuit design. Based on these previous studies, a system level low power static real-time scheduling algorithm of mixed tasks is proposed for FTU in this paper. The simulation experiment shows that this algorithm can decrease the FTU power consumption effectively
