Among the specificities of this bench, used to validate the manufacture and maintenance of the nuclear power plant\u2019s alternators and turbines: a 4 MW CC motor and thyristor power bridge piloted by a separate regulation system.<\/p>\n<p>So the project\u2019s aims were clear:<\/p>\n<ul>\n<li>Compensate for equipment obsolescence<\/li>\n<li>Retake control of the installation with equipment benefitting from recent technology<\/li>\n<li>Ensure the maintainability of the installation with long-lasting equipment<\/li>\n<\/ul>\n                <\/div>\n                                <\/div>\n<\/section>\n\n<section  class=\"bloc-content -content  \">\n    <div class=\"container\">\n                                            <div class=\"txt-img--content\">\n                    <h4><strong>DV GROUP <\/strong><strong>Solution <\/strong><\/h4>\n<p>In order to respond to this problem, we worked with Siemens to offer a 100% Siemens solution allowing greater coherence in the equipment architecture.

Thanks to the implementation of the master\/slave management of the three variators, the continuity of the trials is ensured, even in the case of dysfunction on one of the power modules, including the master, thereby offering increased availability. In addition, the variators have more secure STO entries. As for monitoring and supervision, this is carried out via two WinCC supervision consoles. These allow the archiving and analysis of data from each rotor balancing session. Thanks to the monitoring of all the data relating to the motor\u2019s piloting and operation, our client is now able to precisely identify the causes of any technical problems which may arise and therefore carry out repairs much more quickly, even identifying signs of fatigue upstream in order to carry out predictive maintenance.<\/p>\n                <\/div>\n                                <\/div>\n<\/section>\n\n<section  class=\"bloc-img\">\n    <div class=\"container\">\n                    <img decoding=\"async\" src=\"https:\/\/dv-group.com\/app\/uploads\/2023\/08\/IMG_5979-copie-2-1-2-scaled.jpg\" alt=\"\">\n            <span class=\"legend\">Remplacement des variateurs et du poste de commande install\u00e9s sur un des plus gros bancs d\u2019\u00e9quilibrage de notre client.<\/span>\n            <\/div>\n<\/section>","protected":false},"excerpt":{"rendered":"","protected":false},"featured_media":2085,"template":"","meta":{"_acf_changed":false,"_seopress_robots_primary_cat":"","_seopress_titles_title":"Retrofitting of an impressive balancing bench","_seopress_titles_desc":"We replaced the drives and control station on a bench used to validate the manufacture and maintenance of alternators for nuclear power stations.","_seopress_robots_index":""},"pays":[207],"category-cs":[426],"secteurs-activites":[417],"solutions":[233],"class_list":["post-10956","etudes-de-cas","type-etudes-de-cas","status-publish","has-post-thumbnail","hentry","pays-frankrijk","category-cs-engineering-nl-2","secteurs-activites-environment-energy-en-nl","solutions-aandrijving"],"acf":[],"publishpress_future_workflow_manual_trigger":{"enabledWorkflows":[]},"_links":{"self":[{"href":"https:\/\/dv-group.com\/nl\/wp-json\/wp\/v2\/etudes-de-cas\/10956","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/dv-group.com\/nl\/wp-json\/wp\/v2\/etudes-de-cas"}],"about":[{"href":"https:\/\/dv-group.com\/nl\/wp-json\/wp\/v2\/types\/etudes-de-cas"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/dv-group.com\/nl\/wp-json\/wp\/v2\/media\/2085"}],"wp:attachment":[{"href":"https:\/\/dv-group.com\/nl\/wp-json\/wp\/v2\/media?parent=10956"}],"wp:term":[{"taxonomy":"pays","embeddable":true,"href":"https:\/\/dv-group.com\/nl\/wp-json\/wp\/v2\/pays?post=10956"},{"taxonomy":"category-cs","embeddable":true,"href":"https:\/\/dv-group.com\/nl\/wp-json\/wp\/v2\/category-cs?post=10956"},{"taxonomy":"secteurs-activites","embeddable":true,"href":"https:\/\/dv-group.com\/nl\/wp-json\/wp\/v2\/secteurs-activites?post=10956"},{"taxonomy":"solutions","embeddable":true,"href":"https:\/\/dv-group.com\/nl\/wp-json\/wp\/v2\/solutions?post=10956"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
