Drinking, cooking, and many other activities need the use of water on a daily basis; however, large amount is lost in enterprises public utilities. In light this, we came up with plan to cut down waste. Our goal automate delivery, detect theft, avoid waste, determine pH TDS values using PLC-controlled system. The level can be determined by utilizing laser based liquid Sensor. leakage detected v...

The operation of a distribution system in the presence of distributed generation systems has someadvantages and challenges. Optimal sizing and siting of DG systems has economic, technical, andenvironmental benefits in distribution systems. Improper selection of DG systems can reduce theseadvantages or even result in deterioration in the normal operation of the distribution system. DGallocation ...

Background and purpose: Heterotrophic plate count (HPC) is commonly used to assess the general microbiological quality of drinking water. HPC must be less than 500 colonies per milliliter in drinking water. The aim of this study was to compare the heterotrophic bacteria of bottled water and drinking water distribution system and their relationship with water quality parameters. Materials and m...

Abstract: One of the equipment that can help improve distribution system status today and reduce the cost of fault time is remote control switches (RCS). Finding the optimal location and number of these switches in the distribution system can be modeled with various objective functions as a nonlinear optimization problem to improve system reliability and cost. In this article, a particle swarm ...

In this paper, the methodology of aircraft air distribution system has been analyzed theoretically and experimentally. To achieve that, ducting pressure loss and air flow throw gaspers calculations has been done for cabin ducts in according to exact location of individual air distribution system in the cabin. The length of gasper air flow was compared with the distance between gasper outlet and...

In this paper, a distributed method for reactive power management in a distribution system has been presented. The proposed method focuses on the voltage rise where the distribution systems are equipped with a considerable number of photovoltaic units. This paper proposes the alternating direction method of multipliers (ADMMs) approach for solving the optimal voltage control problem in a distri...

In methods presented to calculate the voltage collapse point, the transmission system is usually the only part of the power system that is completely modeled. Distribution systems are often replaced by aggregate load models because the use of the detailed model of distribution systems in voltage stability analysis not only increases the computation time, but also decreases the probability of co...
