Professor Dr Ernst
Ulrich von Weizsäcker |
VGB CONGRESS 2021 – 100 plusDon't miss the keynote by Professor Dr. Ernst Ulrich von Weizsäcker"Come on! What we have to change to survive" This is the gripping and encouraging title of this year's keynote speech at the VGB Congress in Essen, Germany. Today's world with climate change as the biggest challenge of our time needs a new enlightenment. Many thought patterns still originate from a time when the world was empty, mankind small and nature immeasurable. The biologist, environmental politician and bestselling author Prof. Dr. Ernst Ulrich von Weizsäcker is one of the 100 most influential thinkers of our times. He has been co-president of the Club of Rome since 2012. The list of his awards and titles is impressive: Grand Cross of the Order of Merit of the Federal Republic of Germany, German Environmental Prize, Theodor Heuss Prize, three honorary doctorates, former chairman of the Environment Committee of the German Bundestag, head of the California Environmental University. His lectures are exciting, his energy is contagious. We expect an exciting talk around the topics of climate change, resource conservation and energy efficiency. Don’t miss it! |

Flexibility – Analysis of the effect on power plantsThe operating regime of conventional thermal power plants has changed due to the increased use of renewable energies such as wind power and photovoltaics. The resulting increase in power generation capacity in the power grid also leads to increased downtimes and reduced operating times under full load for the conventional power plants. As a result, these power plants are subject to increased flexible operation. A joined project group consisting of members of the committees TC "Materials & Quality Assurance" and TG "Performance Indicators" examined the question whether the changed operating mode has also led to an increased lifetime consumption of components of the plants. To clarify this question, all relevant data of the components of boiler, turbine and generator, which are part of the VGB database system KISSY, were considered. The results were published in an article in the VGB POWERTECH Journal. The German-language article appeared in issue 1/2 | 2021 and the English-language article in issue 4 | 2021.

New record: 36 percent minimum load reached at the Maithon power plant in IndiaFrom 20 to 28 July 2021, a German-Indian team coordinated by the VGB conducted flexibility test runs at the Maithon power plant. The investigations were carried out in the 525 MW unit 2 of the power plant which is situated in the state of Jharkhand and operated by Tata Power. The record value of 190 MW minimum load was achieved. Further tests with regard to load ramps and coal distribution provided valuable input in order to derive measures for permanent flexible operation.

SO The tests were preceded by months of preparation. An online coal flow measurement and variable orifices were installed on one of the nine coal mills. The aim was to include information on the distribution of coal when evaluating the operating data – particularly with regard to the combustion process – and to test options for equalizing the coal flow. Since the German part of the team could not be present on site due to the corona-related travel restrictions, it was also necessary to set up a remote connection to the power plant control system. In the end, the collaboration worked extremely well despite the distance – everyone involved praised the professional and committed cooperation. |

VGB PowerTech Journal 6 (2021): IT management, Flexibility Editorial Digitalization as a technological enabler for the future energy system Some topics:
VGB-S-401-00-2020-05-EN - VGB-Standard for the Water in Nuclear Power Plants with Light-Water Reactors Part 1: PWR; Part 2: BWR - Now available as eBook!This VGB-Standard shall be the common basis for the operation of the plants. It provides the framework for operating manuals or chemical manuals, but is in no way intended to replace them. The task of these manuals is, among other things, to consider plant-specific features and to make specifications that go beyond this VGB-Standard. This VGB-Standard describes the water-chemical specification for the safe operation of light-water reactors based on the material concept of the SIEMENS/KWU and comparable plants. |
VGB provides energy-related reading material in the home officeAs a consequence of the corona restrictions, a large number of employees in the power industry currently work at home, and thus unfortunately without access to the printed edition of our VGB PowerTech Journal. What could be more obvious than to quickly use the possibilities of digitalisation? In anticipation of an ongoing project to further digitalize publications, VGB offers an online edition of the VGB PowerTech Journal, starting with issue 1/2019.  In order to not only give the existing readership access to our energy and power plant technology information and specialist articles, but also to gain new readership, access is activated for the period of corona-related restrictions via our website. VGB is looking forward to receiving feedback on this offer. |
