iba AG presents new module for power quality measurement
Acquiring energy quality parameters according to IEC standard and detecting causes for grid interference with ibaPQU-S
Electrical power quality assured –the central module unit ibaPQU-S(firmenpresse) - The new "ibaPQU-S" module unit of iba AG based in Germany offers new possibilities for measuring power quality according to the standards and determining the causes for unwanted events in the power grid. Grid interferences due to the increased use of power-electronic systems are an especially disturbing factor. They "pollute" the network with currents that deviate essentially from the sinusoidal shape due to the switching principle of the used IGBTs or thyristors. The highly fluctuating supply of electrical energy due to the increasingly decentralized energy generation additionally aggravates the impairment of power quality in the supply grid. A bad network quality and stability can damage sensitive electronic devices, cause unwanted plant downtimes by protective shut-downs or lead to unnecessarily high energy costs. The ibaPQU-S module provides a perfect measuring solution. In combination with the ibaPDA process data recording it constantly monitors the grid quality and contributes to enhancing it.
The iba power quality measurement system is particularly relevant in plants like steel- or rolling mills or paper machines which are all large energy consumers. But also the operators of HVDC systems or systems for reactive power compensation belong to the target group. In case the iba system is already in use as transient fault recorder, the measurement of power quality parameters can simply be added to the TFR functionality.
Cause analysis: Power quality measurement combined with plant and process data
The ibaPQU-S module unit is a central component of a measurement system which samples net-synchronously raw values like current, voltage and frequency and calculates internally in compliance with standards the characteristic values that are relevant for the grid quality: RMS- and peak values, flicker, crest factor as well as harmonics and interharmonics, phase shift or harmonic distortions. Hence, power flows and events, which influence the grid quality and the whole grid dynamics, can be analyzed. The ibaPQU-S is suited for DC networks, for networks with 50 Hz or 60 Hz and for the railway network with 16.7 Hz.
One important feature of the ibaPQU-S module is the easy integration into a superimposed process and plant monitoring system. The calculated network quality parameters are transmitted via a fiber optic connection to the "ibaPDA" process data acquisition system. There, the time-synchronous process values are aligned by resampling with the net-synchronous power quality values. Thus, measurement values of current, voltage and frequency can be analyzed along with the general plant and process data. In case of fault events, alarm messages can be issued. "With ibaPQU-S, the relation between the operational state of the system and specific changes in the network can be detected. This forms the basis for a root-cause analysis for grid interferences due to the production process", explains Dr. Andreas Quick, head of the product management at iba AG.
Net-synchronous measurement according to the IEC standard
The net-synchronous sampling with ibaPQU-S determines the characteristic values of the standard EN 50160 based on the provisions provided by the standard IEC 61000-4-30 according to class A. Thus, the module can be used for contract-related measurements for accounting purposes.
