Improving Reliability and Energy Efficiency of Three Parallel Pumps by Selecting Trade-Off Operating Points
نویسندگان
چکیده
Reliability, along with energy efficiency, is an important characteristic of pump units in various applications. In practical applications, it to strike a balance between reliability and efficiency. These indicators strongly depend on the applied control method unit. This study analyzes trade-off for regulating system three parallel pumps equipped only one frequency converter (multi-pump single-drive system). A typical operating cycle pumping variable flow rate requirements considered. The proposed compared traditional regulation, when change point achieved by changing rotation speed, maximum reliability. It shown that makes possible ensure sufficient multi-pump operation without significant increase consumption.

Optimal Trade-off Between Energy Efficiency and Average Delay
In wireless networks consisting of sensors and mobile devices, battery power is a severe resource constraint. Energyefficient communication techniques are therefore crucial to the long-term survivability of the network. In communication theory, it is well known that for a bandlimited additive white Gaussian noise (AWGN) channel with bandwidth W and onesided noise spectral level N0, the minimum ...

Energy consumption by computer systems has emerged as an important concern, both at the level of individual devices (limited battery capacity in mobile systems) and at the societal level (the production of Green House Gases). In multicore architectures, applications may be executed on a variable number of cores and these cores may operate at different frequencies. The performance and energy cos...

متن کاملImproving Energy-Efficiency of Static Schedules by Core Consolidation and Switching Off Unused Cores
We demonstrate how static, energy-efficient schedules for independent, parallelizable tasks on parallel machines can be improved by modeling idle power if the static power consumption of a core comprises a notable fraction of the core’s total power, which more and more often is the case. The improvement is achieved by optimally packing cores when deciding about core allocation, mapping and DVFS...
