Power Quality Monitoring

▼Chapter 5SoftwareGridVisSoftware for grid visualisationThe GridVis software for programming and grid visualisation,which is part of the standard delivery package ofall power meters, enables a simple and complete parameterisationof the power analysers. Customer specificvisualisation of the energy supply is possible with thetopology view. The individual measurement instrumentcan also be operated online using the mouse, if the correspondingdevice supports this feature. Measurementdata can be directly recorded on the PC in online graphs.Furthermore, GridVis offers convenient opportunitiesfor presentation and analysis of historical data from thedatabase. The automatic ring buffer download and integrateddata management has a particular positive effectin medium and large sized projects as data can be storedin various database formats. With the graphical programming,user specific programs can be created for themeasurement instruments families UMG 604, UMG605, UMG 508 and UMG 511.▼Main featuresThe GridVis grid visualisation software enables the following: Visualisation of measurement values Automatic ring buffer readout from the connected measurement instruments Storage of the data in a database Graphical presentation of online measurement values Configurable topology overview with freely selectable register levels Configuration of the measuring instruments Graphical programming of user programs or programming with Jasic ® source code Parameterisation, visualisation, data management and analysis Measurement data analysisApplicationsThe GridVis software has a multitude of applications:The development of extensive energy management systemsVisualisation of energy supplies with the help of a topology viewDocumentation of power quality for freely definable periods of timeAnalysis of the root causes of faultsCost centre management i.e. simple and precise electricity cost calculationStabilisation of energy supply through the alarm function when limit values are exceeded e.g. overvoltage or short-term interruptionImprovement of power quality e.g. harmonic analysis for fault detectionLoad profile analysis e.g. consumption prognosis for electricity contract negotiations149
