Hamburg, 19. April 2021<\/em>\u00a0\u2013 greentech, independent expert for technical consulting and operational management of photovoltaic systems, has recently started offering a high-frequency analysis for PV systems in cooperation with the grid specialist morEnergy. The analysis involves the measurement of currents, voltages and resonances using a high sampling rate up to 150 kilohertz. This offers the possibility to identify hidden and avoidable loads on the respective system components which are connected to the internal or external grid. The analysis of the two Hamburg based companies goes far beyond the usual power quality standard measurements.<\/p>\n

Power quality effects in the super-harmonic range so far complex and difficult to comprehend<\/strong><\/p>\n

Nowadays, modern power electronic systems pulse at frequencies above 2 kHz. Due to net resonances and poorly dimensioned or damaged filters, increased supraharmonic current and voltage levels may occur. \u201cEspecially in high-performing systems, components such as filters, cables or transformers often heat up dramatically, which leads to faster ageing,\u00a0 defects in the components and ultimately a failure of the system,\u201d explains Dr.-Ing. Michael Jordan, CTO and Co-Founder of morEnergy. \u201cUp to now, the normative regulations have not dealt sufficiently with power quality effects in the super-harmonic frequency range, as they are complex and difficult to understand,\u201d the expert in measurement technology says. \u201cThis is why we developed a new type of measuring device that covers precisely this range. We are pleased to be able to offer this application to the PV industry in co-operation with greentech.\u201d<\/p>\n

Better network transparency reduces repair costs and yield losses \u00a0<\/strong><\/p>\n

The special analysis by greentech and morEnergy does not only provide plant operators with a comprehensive insight into the grid topography \u2013 it also reduces maintenance costs and yield losses. \u201cTogether with morEnergy as an expert partner on the subject of grid effects and grid monitoring, we are able to take the subject of power quality of PV plants to the next level,\u201d says Greentech Managing Director J\u00f6rn Carstensen. Greentech is responsible for carrying out the measurements on-site and accompanying the customer from the initial contact, through the analysis, up to the development of measures to eliminate sources of interference. \u201cWe are convinced that we are able to offer our customers real added\u00a0Wealth Accelerators<\/a>\u00a0<\/span>value in terms of the longevity, yield security and transparency of their plant.\u201d<\/p>\n

morEnergy<\/strong><\/a>\u00a0is an innovative engineering company for power grids and renewable energies based in Hamburg. The company\u2019s unique selling point is the determination of grid impedance. For this purpose, the grid specialists developed measuring devices for the low and medium voltage level. These devices do not only measure the power quality \u2013 they further determine the network topography up to the 500 kHz range if required. This achieves an unprecedented level of detail. Figuratively speaking, it makes the current 2D representation become a 3D real-time image of the electrical network.<\/p>\n
