This paper present the design and implementation of a pilot smart grid in the colombian distribution network. This smart grid consists in a low voltage system connected to the existing electricity distribution network, which consider distributed generators and control, supervision and communications systems. These elements allow to provide electric power generation under the scheme of smart grid,...
Aiming at the features of environmental information monitoring, a multi-parameter monitoring system is designed based on low-power ZigBee wireless communication technology to improve overall the level of system automation and monitoring. By wireless sensor networks the data is collected and processed real-time and at the receiving end the data is received, saved and displayed to achieve temperature...
Companies are involved in a high competition for reducing the cost of production in order to maintain their market shares. Since the costs of maintenance contribute a substantial portion of the production costs, companies must budget maintenance effectively. Machine deterioration prognosis can decrease the costs of maintenance by minimizing the loss of production due to machine breakdown and avoiding...
There has been a growing interest in using the soft computing techniques for distributed data processing in monitoring systems during last years; wireless sensor network is an example which can be utilized to record and process the environmental conditions in transportation systems. In this paper, by using knowledge based soft computing techniques, the reliability of the sensory records is evaluated...
Exact estimation of battery state of charge (SOC) is important for a monitoring system, which is the basis of a energy management system (EMS) in electric vehicles. This paper presents a combined method for estimating the battery SOC for electric vehicles. Diagonal recurrent neural network (DRNN) and Kalman filter (KF) were used to estimate battery SOC respectively. Then the two methods were combined...
Wind energy is the renewable energy source with a higher growing rate in the last decades and can be considered a hope in the future as a clean and sustainable energy. With the huge proliferation of wind farms, as an alternative to the traditional fossil power generation, the economic issues dictate the necessity of monitoring systems to optimize availability and profits. Tools to detect the onset...
In Fast Breeder Reactor (FBR), shutdown system is envisaged by Safety and Control Rod Acceleration Movement by using (SCRAM) signals. These SCRAM signals are realized with redundant triplicate sensors, which are made available at different locations of reactor. In this case sensors should be in healthy condition to run the reactor in trouble free manner. To know the health status of sensors a monitoring...
Until now, a number of cutting tools and cutting methods have been developed for improving the machining processes, however they have some difficulties resulting from tool wear and failure. This study considers on-line monitoring of tool wear and failure in metal cutting processes. The proposed on-line monitoring system consists of two parts: the one is the on-line data acquisition system with sensors...
The paper proposes a monitoring system, which helps to regulate the proportion of air and fuel in vehicles to increase combustion engine efficiency and to reduce the amount of harmful gases thus emitted. A human operator generally performs the task of opening or closing the valve of fuel injection pump of locomotive engines to control amount of air going inside the combustion chamber. An artificial...
The paper analyzed the character, the origin and the danger of impulse interfere in the coal mine monitoring system. The impulse interfere in monitoring system has characters of sparse, shortness, and high amplitude. According to those characters, the adaptive denoising method based on FOCUSS was proposed to eliminate the impulse interfere. In the experiment, according to the procedures proposed by...
