Accurate training on electronic measurements can be obtained while experimenting with real sensors, electronic circuits and equipments. The paper presents an experimental system that allows the study and testing for two ultrasonic sensors, the remote programming for one of them and the monitoring of switching output for each sensor. A programmable logic controller performs the sensor remote programming...
This paper introduces a model for dynamical reliability parameters assessment based on Bayesian methodology, which can be applied, with a good approximation, either for serial, parallel or mixt subsystems configurations. The failure data for component, subcomponent or elements are included in posterior distributions, enabling the extrapolation of failure parameters to similar entities in related systems...
Based on a synthetic analysis of the groundwater thermality in the Upper Pannonian and the geothermal potential of the NW region of Romania, the article presents an analysis of the conversion of geothermal energy into electricity. This analysis was made in terms of the thermodynamic calculations necessary for the design of the geothermal power plants based on Kalina Thermodynamic Cycle, as well as...
The loadbreak cutout control is most often performed from the zonal load dispatcher level. The system presented in this paper performs the remote control and permanent monitoring of some loadbreak cutouts which run on a 20kV power line. The monitoring and control is directly carried out by the zonal load dispatcher. This remote control alternative provides more operativity and safety in decision making...
This paper presents an experimental system that allows the study and testing of two proximity sensors (inductive and capacitive) and their use in an application. The guideline for studying these devices enables students to test the working modes of Turck inductive and capacitive proximity sensors, apply their previously acquired theoretical knowledge about sensors, transducers and electronic circuits...
The paper presents the possibility of using geothermal energy for electricity production at average temperatures. The authors considered two options for their study, namely binary cycles (organic Rankine and Kalina) and the thermoelectric generators. After a comparative study for the proposed solution, was chosen Kalina cycle and was proposed a solution for a geothermal power plant. The advantages...
Protections for generators have been studied by many researchers in recent years. This paper shows how to implement the hydrogenerator loss of excitation protection function using a programmable electronic module organized around a PC/104 central unit. This equipment samples the currents and voltages of all three phases, the homopolar current and homopolar voltage, performs data processing, allows...
Many power quality problems are generated by various electrical events (faults, disturbances, etc.). This paper presents the PC-08/104 equipment for monitoring and analysis of transient electrical events in power systems. It is a programmable electronic module which runs according to the signals provided by the transducers that take over the process parameters. PC-08/104 performs the acquisition of...
