This paper presents a design approach to an embedded monitoring system found in distributed renewable energy power systems. The grid connected distributed power system, delivers energy to the consumers located on the micro-grid, operating at distribution voltage levels, and also delivering the remaining surplus energy to the main distribution grid. The aim of this paper is to present the development...
This paper describes logic and circuit design features of a heterogeneous tri-cluster deca-core CPU complex incorporated into a 10nm FinFET mobile SoC for smartphone applications. Similar to Helio X20 [1], the Deca-Core compute function contains three separate clusters of ARMv8a CPUs. The high-performance (HP) cluster is updated to incorporate the most power-efficient out-of-order Cortex-A73 CPU,...
A system for monitoring patients for the cold sweat symptom and giving instant signal if they break into sweat has been proposed in this work. A method was devised to create such a system for indicating profuse perspiration by continuous monitoring of Galvanic Skin Resistance. For this purpose a circuit was designed, an algorithm was created and certain steps were followed towards achieving the goal...
The design and implementation studies of a remote monitoring system are presented in this study. The proposed design is improved in terms of smart metering infrastructure based on current, voltage, and power measurements. The communication among the photovoltaic (PV) panels and host PC is performed by designed ZigBee transceiver system. Sensing circuits are very important devices to measure for both...
This paper describes the operation and calibration modes for an experimental monitoring system of a photovoltaic (PV) plant with greater emphasis on the Maximum Power Point Tracker (MPPT). In order to optimize the energy production and therefore the economic convenience, it is very important that MPPT device works properly and that the measurement of PV electrical quantities is not affected by excessive...
Secure operation of power systems requires proper monitoring of the system operating conditions. PMU (Phasor measurement units) are the device which uses synchronized signals from the Geometric Positioning Satellite System(GPS) satellites and provide the phasors information of voltage and currents at a given substation. To avoid redundant use of PMUs, the optimal locations for the Phasor measurement...
oscilloscope is used to measure the voltage ripple in PLTP Darajat, but experienced problems because the oscilloscope can not measurred simultaneously as many as 40 points measuring. In this paper, we will show the results of the design and implementation of the PLC to measure the ripple voltage total of 40 measuring points simultaneously. This research was implemented in geothermal power plants Darajat...
This paper presents the design of a solar powered energizer and on-line fence voltage monitoring system for electric fences. The fence voltage is continuously monitored and transmitted to the Central Monitoring System. Transmission of signal from the fence lines to the central monitoring system is by using Zig-Bee wireless network. If the fence voltage is reduced below the rated value, that fence...
In this paper, we present the new French Cloud management software called Compatible One. Compatible One is an open source cloud services broker i.e. a cloud service management software with brokering capabilities. Compatible One can provision, deploy and manage any type of cloud services, these services being provided by heterogeneous service providers selected according to Service Level Agreement...
Degradation cause by ageing is one of the major problems in the power system equipment such as transformer and machine. A continuous assessment method is the new method on assessing the condition of equipment that had gained an interest lately compared to the traditional time-based maintenance. One of these methods is known as condition-based monitoring. This predictive maintenance with the aid of...
The paper presents the results of the correct on-line evaluation of the current technical condition of the electrical equipment in high voltage substations owned and operated by Romanian Power Grid Company — CNTEE Transelectrica SA, using intelligent monitoring systems. The paper describes parts of the intelligent systems dedicated to on-line monitoring of all primary equipment used in the 400/110...
Operational parameters that may be observed by battery monitoring equipment used in stationary applications and the relative value of such observations are discussed in this guide. Although a list of commercially available systems is not given, a means for establishing specifications for the desired parameters to be monitored is provided.
This paper considers electrical power as a product which should cover certain quality norms. The voltage characteristics limits according to the standard EN 50160 are accepted as quality norms. The article discusses the approaches to the monitoring and inspection of the electrical power quality. On that aim, two configurations for remote control of the power quality analysers by a computer were tested...
There are many manufacturers around the world providing power quality (PQ) monitoring and digital fault recording (DFR) solutions. Different monitoring requirements, monitoring practices, and new standardization make for a diverse range of available solutions. The first section of the paper will summarize the requirements and challenges of a modern PQ and DFR monitoring system. The second section...
Power quality (PQ) has become a non-negligible issue for DNOs. More and more sites are being monitored permanently throughout their networks covering almost all voltage levels. Due to the continuously increasing number of measurement sites, certain issues become more and more evident. PQ analyzers usually run only in combination with proprietary software and data transfer methods. The interoperability...
This paper discusses a project of monitoring a university campus grid using a network of smart meters. The aspects of hardware, software, and monitoring are provided. Some aspects of the benefits of this monitoring in terms of power quality, grid efficiency, and health monitoring are discussed in the paper.
Increased global interest in environmental issues has led to demands for power consumption reduction of home electronics. Home energy management systems (HEMS) achieve this by monitoring and controlling the power consumption of home electronics. To reduce power consumption adequately, we need to flexibly customize HEMS based on user policies. However, conventional HEMS are completely systematized...
It's necessary to measure each monomer cell voltage of the fuelcell stack in order to ensure fuelcell stack to operate normally. Therefore, a host computer monitoring management software for fuelcell voltage polling measurement based on virtual instrument programming software LabVIEW8.5 was developed. The host computer monitoring management software could show fuelcell's operation voltage to user...
In actual oil-producing wells, most oil-pumping units are running in awful circumstance, and their location is irregularly, so the electric power control for the oil-pumping units is difficulty. The electric power correlate data of the oil-pumping units will cost much time for the professional to collect. Based on the analysis of actuality, an electric power control system design is introduced according...
This article presents a software developed for analysis of phenomena related to the power quality (PQ) in industrial systems, as variation of voltage, harmonic distortion and imbalance voltage, where the results are conveniently visualized in an user-friendly interface. This software intends to replace, in most situations, measurements made by traditional meters of PQ (equipment of high cost and rare...
