Software GridVis

 

 

The GridVis software is part of the standard package supplied with the UMG 604 power analyser and the UMG 103 universal measuring instrument.

This software can be used to present the measurement values as actual values online and a graphic presentation of the values read from the measurement value memory is possible.

The topology overview guarantees a quick overview of the complete electricity network. The GridVis software also serves the purpose of parameterisation of the measurement instruments. Furthermore, the creation of customer-specific programs is possible using our own developed program language, Jasic®, or the user-friendly graphic programming periphery.

Software for grid visualisation

The GridVis programming and grid visualisation software, which is part of the UMG 604 and UMG 103 standard delivery package, enables a simple and complete parameterisation of the UMG 604 and UMG 103 power analysers. Customer specific visualisation of the energy supply is possible with the topology view. The individual measurement instrument can also be operated online using the mouse. Measurement data can be directly recorded on the PC using the online presentation. Furthermore, the GridVis offers convenient opportunities for presentation and analysis of historical data from the database.

The automatic ring buffer down load and integrated data management has a particularly positive effect in medium and large sized projects as data can be stored in various database formats. In addition to the UMG 604 and UMG 103, the UMG 507, UMG 96S and UMG 510 instruments are also successively integrated into the software. User programs can be freely programmed for the UMG 604 with the graphic programming.

Characteristic feature

The GridVis grid visualisation software enables the following:

  • Visualisation of measurement values

  • Automatic ring buffer readout from the instruments

  • Storage of the data in a database

  • Graphic presentation of online measurement values

  • Configurable topology overview with freely selectable register levels

  • Configuration of the measuring instruments

  • Graphic programming of user programs or programming with the Jasic® source code

  • Parameterisation, visualisation, data management and analysis

Applications

The GridVis software has a multitude of applications:

  • The development of extensive energy management systems

  • Visualisation of energy supplies with the help of a topology view

  • Documentation of the power quality for freely definable period of time

  • Analysis of the causes of faults

  • Cost centre management i.e. simple and precise electricity cost calculation

  • Stabilisation of energy supply through the alarm function when limit values are exceeded e.g. overvoltage or short-term interruption

  • Improvement of power quality e.g. harmonic analysis for fault detection

  • Load profile analysis e.g. consumption prognosis for electricity contract negotiations

Programming and configuration

The UMG 604 power analysers are completely parameterised with the help of the GridVis software. The instruments can be given any name and the CT and PT values can be set. Trigger values for the measurement of events and transients, as well as the measurement values which are to be stored and their recording intervals are determined. Limit values for the monitoring function of the digital outputs are programmed using the comparator or the pulse value for the digital inputs or outputs is established. The external temperature sensor can be selected. The time server for time synchronisation is also determined. If it is necessary to carry out an update on the measuring instrument, this can conveniently be done in the programming mode without the instrument having to be dismantled or returned to Janitza. The most recent updates for software and instrument firmware is available free of charge at Software.

Unlimited programming options

The Jasic® programming language opens up so many new opportunities because you are no longer tied to just the fixed integrated functions in the instrument. You can expand the instrument to include your own functions. Up to seven freely definable user programs can run at the same time.

The graphic programming option for user programs is a fully new aspect in the field of digital power analysers. These can be used to create user-specific programs such as free programming of inputs and outputs or the issue of reports when a defined limit value is reached. In addition to the user-friendly graphic programming, the user is free to program the source code directly.

Online data

All measurement values are available in the online measurement mode as a line graph or bar chart. The line graphs are permanently updated and the oldest data is deleted after a while. Two scales for measurement data in two units can be created. Any number of measurement data from each unit, including from several measurement instruments, can be observed in the same graph. The colours in the graph can be changed as required.

Topology overview

A device view can be called for up for each UMG604 which is found in the network. It is not only possible to observe the actualdisplay but to control the unit completely by remote control as if you were on site. Furthermore, any jpg document can be assigned e.g. a drawing of buildings or distribution systems. All measurement data for the UMG device can be presented simultaneously online.

Event and transient browser

Freely defined periods of time can be checked with regard to transients and events using the two event and transient browser functions. These functions (compare illustration: transient browser) are especially important for error analysis.

Data storage

The UMG 604 contains a data memory space of 128MB. The measurement data are stored in a SQL database when the memory data are downloaded. The Derby, SQL and MySQL formats are available for saving the data. Storage in a MySQL database or a Microsoft SQL server database is recommended because these are faster than the Derby database. This has a particularly positive effect for larger projects. MySQL can be downloaded free of charge from www.MySQL.org.

Offline data

The data which are saved in the database can be presented as a line graph, bar chart or histogram in the GridVis software. The data are stored in the database according to parameters, year, month and day. The data can, therefore, be selected accordingly. Particularly interesting periods of time can be enlarged with the zoom feature. The graphs can be provided with titles and comments and can be printed out. The display of transients and events also takes place here a the transient or event browser. The flag browser can be used to examine whether measurement data are missing at certain periods of time or whether the data are not reliable.

Licences

The following extension modules are available for the GridVis software as an option:

GridVis licence 1, item number 51.00.117
Graphic programming module – write/read Modbus
This allows the graphic programming of the UMG604 as a Modbus master for reading/writing Modbus units using the graphic programming.

GridVis licence 2, item number 51.00.118
Database driver for the Microsoft SQL-Server
This enables the data exchange between the GridVis and a SQL server. Without this driver, the GridVis software uses the integrated Derby database.

GridVis licence 3, item number 51.00.119
Database driver for the MySQL-Server
This enables the data exchange between the GridVis and a MySQL server. Without this driver, the GridVis software uses the integrated Derby database.

GridVis licence 4, item number 51.00.120
Devices driver for generic Modbus devices
