Abstract

Increasing unplanned energy demand increase has led to network congestion, increases power losses and poor voltage profile. To decrease these effects of an unmanaged power system, distribution network reconfiguration provides an effective solution. This paper deals with improving the power losses and poor voltage profile of the Phulchowk Distribution and Consumer Services (DCS) via the implementation of an optimum reconfiguration approach. A Genetic Algorithm (GA) is developed for the optimization. Further, it tries to answer to what extent can we improve the distribution system without overhauling the entire network. The developed simulation algorithm is firstly put into work on the IEEE 33 bus system to better its voltage profile and the poor power losses. The effectiveness of the developed system is validated as it reduced the voltage drop by 5.66% and the power loss by 25.96%. With the solution validated, the algorithm is further implemented in the case of Pulchowk DCS. After reconfiguring the system in different individual cases, optimum network reconfiguration is selected that improved the voltage profile by 3.85%, and the active and reactive power losses by 44.29% and 45.54% respectively from the base case scenario.

Abstract

In an electric power system, electricity is generated by the power plant and then channeled to a transmission line and then distributed to consumers, in the process of distributing electrical energy, the system does not always work in normal conditions, sometimes the system can experience disturbances such as one-phase, two-phase, and three-phase disturbances. This interference can disrupt the electrical system and can damage equipment if left unchecked, therefore it is necessary to install a protection device that can decide the interference so as not to damage other equipment when a disturbance occurs. Here the protection device used is a circuit breaker. In a fault condition, the circuit breaker must be able to separate the points of the fault so as not to damage other electrical equipment. In this case, to determine the capacity of the best protection device for the system, a short circuit fault simulation is performed. To simplify the calculation process here the author uses the help of ETAP software (Electrical Transient Analysis Program).

Abstract

Every year the number of climbers increase, there are at least 70,000 climbers including researchers. The increase in the number of climbers will certainly increase the mortality risk of hypothermia. At least 18 people died from hypothermia in 2014 to 2015. The risk of hypothermia can be reduced by handling such as providing warmth to the patient. Warmth can be created by using a tool that produces the right heat, easy and safe to use, easy to carry and also affordable. This is the basis for researches to conduct research on designing heating products in tents as an effort to prevent hypothermia. This research uses the QFD (Quality Function Deployment) method in processing the results of the consumer’s voice, design the product concept, screening and selecting concept and analysis the final product design. Based on the data collection and processing that has been carried out, there are 10 criteria for consumer needs and interests for product, including practical tools to carry, safe to use, can warm the body to have additional functions as cellphone chargers. While the alternative concept chosen in the form of cylindrical tube, using a Li-ion battery, and a frame made of polypropilene plastic. From the chosen concept, then a heating lamp model is designed in the display when used and stored.
