This paper presents the optimization of integer program, which combines linear lighting with energy saving as the objective function to manage the illumination. Most illumination usually don't abide by the design limits at the initial time of installation, so this would make the intensity of illumination extremely high. In this paper, an improved method of optimizing the energy-saving objective function...
Today, the so-called ping-pong is from the traditional tennis, originated in the late 19th century England, due to the space and weather restrictions, this exercise is moving from outdoor into indoors, and uses the table as a venue, then, slowly transfer into the current ping-pong. In 1998, the Summer Olympus Games make the exercise as an official item in the game; hence, it becomes a popular sport...
He analysis of electrical quantities is important for the evaluation of power signal. However, there are many different analysis methods for power disturbances in the literature. This circumstance would lead to the difficulty in the design of a low-cost measurement system. In this paper, the design and implementation of a virtual measurement system based on the adaptive neural network (ADALINE) is...
The advancements in technology cause the development of science and technique upwardly, therefore the city become skyscrapers. For convenience and saving time, people invented the elevator. The elevator was invented in 1880, until now the functions was exactly the same state. Nowadays still have not the remaining weight display function at the entrance of elevator, so this paper propose by using PIC...
The synchronized measurement is important to the applications in power system. With the obtained power information, the conditions of power system can be easily realized, such as power quality, transient stability, and efficiency of energy usage, etc. In this paper, the design of phasor measurement unit for power system monitoring based on neural network is proposed. Through the experiment, the performance...
In this paper, an educational platform to improve the test and the evaluation of the experimental data in electric machine laboratory is developed. The system is complement to the course taught of electric machines to undergraduate students. Our proposed system can automatically acquire the experimental data from data acquisition device on the personal computer and transfer the data through interface...
Course testing has long been regarded by teachers as one of the best means to objectively evaluate whether students have achieved the instructional goal or objective set up by teachers. The purpose of course testing is to help teachers understand the degree to which students have mastered a course. Students' test scores on a course may serve as a referential index whereby teachers can modify their...
For the development of smart grid, the effective detection of power quality events is a very important task for the power system monitoring. Voltage sags, interruptions, and voltage swells which usually produce large losses in commercial and industrial consumers are the main events in power systems due to the sensitivity of equipments to these voltage variations. In this paper, a simple rule-based...
This paper presents an efficient method for placement of shunt capacitor in a harmonic polluted power system. The planning problem is formulated as an unconstrained optimization problem. In the approach also considers probabilistic characteristics of voltage, current and impedance of fundamental and harmonics in a power system. The objective function is the total system power loss. The shunt capacitor...
Pollution of noise, frequency deviation and harmonics may make operating problem of devices in power systems. An extended real model of Kalman filter which is suitable for harmonics estimation of power system is proposed in this paper. Not only the frequency deviation is observed, but also the result is with a better accuracy, even if the power signals are influenced by noise. Finally, the performance...
