Fig. 13/91 SIMEAS Q

Description SIMEAS Q is a compact, cost-effective power quality recorder and has been developed to provide full-area monitoring of power quality according to EN 50160 and IEC 61000 standards. The increasing use of non-linear energy consumers or unbalanced loads has a huge impact on the network quality of the electrical power supply. Many electrical devices in the industry need a proper power supply for accurate operation. A poor quality of the power supply affects the operational reliability inside a network of different consumers and can lead to a costexpensive loss of the availability of different devices, for example NC machines. Therefore a coverage acquisition und evaluation of the quality of energy supply is necessary. SIMEAS Q devices are installed at various measuring points in order to record a series of measurements of the required values for an analysis of the network quality. In addition to all relevant measured variables, the SIMEAS Q can also record system disturbances, always when an upward or downward limit value violation has occurred. The recorded values can be called up and evaluated using a PC.

SIMEAS Q is available in 3 device versions with the following communication interfaces: – RS232 – RS485 – PROFlBUS-DP Furthermore the device version SIMEAS Q with PROFIBUS-DP interface opens up another area of application. Together with programmable control systems (PLCs), it can be used as a “sensor” for electrical measured variables. The basic task of data transmission and archiving for several SIMEAS Q devices is automatically managed by the “SICARO Q Manager” software installed on the PC, whereby the data transmission route between the individual SIMEAS Q devices and the PC can be achieved in a number of ways. The SICARO PQ is a software product for evaluating measured values with respect to international standards, e.g. EN 50160 or IEC 61000 or according to definable compatibility levels. For analysis with SICARO PQ, the measured values are automatically first fetched and stored by SICARO Q Manager software. SICARO PQ automatically accesses the stored measured values and automatically initiates event analysis and reporting and the output in the form of HTML, print or report file.

Connection Different connection methods or system configurations are possible, depending on the application and existing infrastructure. One is to use a central PC as the master. It is then possible to set up a system for measured-value acquisition and evaluation using the SICARO Q-Manager software. For long distances individual devices or the complete RS485 bus with Ethernet converter may be used. An other possibility is to link up to a PLC system where the SIMEAS Q is connected to the central master as a slave. The PROFIBUS interface, implemented and certified according to standard EN 50170 Volume 2, enables fast adaptation to a PLC systems. That way, measured values acquired with the SIMEAS Q can be used for control tasks.

Detailed information on how to retrieve measurement data from SIMEAS Q via PROFIBUS is available to everyone in the SIMEAS Q user description1). The open communication interface permits data transmission between SIMEAS Q units and all types of PROFIBUS-DP Masters, such as programmable controllers or personal computers (with integrated PROFIBUS-DP hardware). Function blocks are available for the SIMATIC S7-300 and S7-400 PLC systems, with an internal or external DP interface1). They permit fast configuration of customer-specific PLC programs for applications combining SIMEAS Q with these PLC systems. Functions Recording of measured values is possible in two modes, which can be used simultaneously.

• Continuous recording • Recording in the case of a limit value violation In “continuous recording“ mode, the SIMEAS Q can record measured quantities as defined in the standards (e.g. EN 50160). Acquisition of maximum and minimum values of measured quantities within the measurement period (averaging time) is also possible.

Fig. 13/93 SIMATIC S7 PLC as the master station with various PROFIBUS-DP slaves

“Recording in the case of limit value violation” means that measurement data are recorded when the average measured value violates one or more defined upper or lower limits (thresholds). When a limit value is violated, the current time and date information and the mean value since the last limit value violation of that measured quantity are stored in the memory. This type of recording is primarily used for recording voltage dips. To record voltage dips, the lowest possible averaging time of 10 ms is selected. During measurement, the SIMEAS Q compares the rms values = 10 ms with the set thresholds and is thus able to record very short voltage dips. Relay outputs The SIMEAS Q is fitted with 2 relay outputs (opto-relays). One of the following functions can be assigned to these outputs:

• Energy metering pulse per settable energy value for: − Active energy, energy import − Active energy, energy export − Reactive energy, capacitive − Reactive energy, inductive − Apparent energy • Indication active power import (contact open) or active power export (contact closed) • Limit power factor (PF (cos ϕ)) (contact closed for as long as PF is lower than a settable limit value) • Pulses an voltage dips (contact closed for 500 ms if violation of the threshold below rated voltage detected) The relay outputs enable the SIMEAS Q to be used for acquisition of measured values and for energy metering.

Software The SIMEAS Q PAR software and SICARO Q Manager software can be downloaded free of charge via the Internet at www.powerquality.de or www.simeas.com. If SIMEAS Q units are connected to a PLC system as slaves, only the SIMEAS Q PAR software is required to set the SIMEAS Q parameters. To configure the SIMEAS Q, a cable is required to connect the PC. A separate parameterization package is available for this, containing the parameterization software and the connecting cable required for the respective unit version.

SIMEAS Q PAR configuration software The SIMEAS Q PAR parameterization software is executable under the Windows 2000/XP operating systems. The software allows you to define the device address, so that each device is uniquely identified and to configure the SIMEAS Q for the communication protocol to be used (RS232, RS485 or PROFIBUS DP) in order to prepare it for the measurement task. SICARO Q Manager – software for measured-value acquisition The SICARO Q Manager software, executable under the Windows 2000 / XP operating systems, is a software product for configuring a system with several SIMEAS Q units and for gathering the measured values from the SIMEAS Q units, displaying them, storing them in PQ archives and making them available for further processing. • Functional scope − Graphic configuration of a system structure with the connected SIMEAS Q units. − Automatic transmission and storage of the measurement data from the connected units. − Display of retrieved measurement data. The display takes the form of rotary dial instruments, bar charts and numerical values.

Software SICARO PQ - the analyzing tool The SICARO PQ software, executable under the Windows 2000 / XP operating systems, is a software product for evaluating measured values based on international standards, e.g. EN 50160 or IEC 61000 or according to customer-specific compatibility levels. For analysis with SICARO PQ, the transmitted measured values first have to be archived using the SICARO Q Manager software. The archived data are then the data source for the analysis software. For evaluation and reporting, the reference levels have to be applied and a reporting template has to be selected. Evaluation procedure • Manual selection of data archive • Manual selection of measured quantities and time range • With selected settings for analysing reports (quality profiles) by using of functional task scheduler it is possible to create automatic jobs for printing reports or creating reports in HTML format.
