LabVIEW contains a comprehensive set of tools for acquiring, analysing, displaying, and storing data, as well as tools to help you troubleshoot the code you write. The LabVIEW is a programming environment based on G language (graphic language) core intended mainly to develop applications for data control and acquisition, their analysis and results presentation. In order to improve quality evaluation of energy to industrial consumers, we proposed a specialized software developed in LabVIEW that allows reading of measured data obtained from a network analyzer (in this case CHAUVIN ARNOUX - CA 8352), processing data to create a clear picture about the quality of electric energy in an industrial consumer. Based on these considerations and according to present laws of energy efficiency the industrial consumers are obliged to carry out an energy balance once every four years.
According to the standard of performance for the electricity supply utility with regulated tariffs the supplier has the obligation to meet the parameters of electric energy quality. The values accepted for most quality indicators are standardized by energy standards and prescriptions. The quality indicators are determined at the limiting points between the electric wiring of the supplier and of the consumer which constitute the load: - primary quality indicators (power supply frequency variations, voltage variations, dips, power failure, temporary surges, transients) are given by the production, transport and distribution of electric energy - secondary indicators (harmonics, interharmonics, voltage fluctuations, unbalances) are given by the disruptive operation of industrial consumers. The quality of electric energy – is assessed using quality indicators for specific electrical quantities, voltage, frequency and respectively for the electricity supply utility in terms of the duration of power failure. Quality indicators of electric energy, depending on the place of occurrence of disturbances are indicators of primary and secondary quality indicators. An incident in the facilities of a manufacturer or a consumer may lead to a transient that would affect all consumers connected at the same power supply points. An incident in any of these grids can lead to an interruption in the supply and/or dips that - depending on the structure of the grid - can produce effects on consumers and producers connected in a same power supply points and even further. The operation of industrial users can be accompanied by the input of significant disturbances in the electric power supply network in the form of voltage fluctuations, voltage dips and swells, unbalance which can translate into a reduction in the quality of electricity supplied to the consumers connected in the network. Introduction The quality of the electric energy is influenced by the activity of the manufacturer, the transmission and distribution provider, the supplier as well as the electric power consumer activity.

Using the software application developed in LabVIEW, full quality analysis of electric energy can be done at the user's premises.ġ. The software application enables creation of customized reports with varying ease of use and flexibility. Based on the data obtained from the measurements and using the interface created in LabVIEW, it was possible to carry out the analysis of the average hourly consumption, the power factor, the wave forms of the current and voltage, the analysis of the current and voltage harmonics. A software application was made to allow reading of files and processing them (creation of data tables and charts). The data processing was achieved using LabVIEW software in terms of the two types of quality indicators.
Transients occur at this limiting point, with negative effects on the consumer, as well as on the electric power supply network. The measurements were carried in the power supply point where the quality of the electric energy is influenced by the activity of the manufacturer, the transmission and distribution provider, the supplier as well as the electric power consumer activity. This paper presents a case study for monitoring the quality of electric energy in an industrial manufacturer of technical rubber and reclaimed rubber products.
