Patent number: 11923687Abstract: A bipole power transmission scheme with two independent converts, two power feed and one return conduit. During operation of the bipole power transmission scheme under abnormal conditions, when a return conduit is faulty and unable to provide a return current path, each converter controller is programmed to monitor the first power feed in the first transmission conduit and the second power feed in the second transmission conduit and, if the first power feed in the first transmission conduit and the second power feed in the second transmission conduit differ from one another, at least one converter controller modifies the power infeed from its corresponding power source to reduce the difference between the first power feed and the second power feed.Type: GrantFiled: March 16, 2021Date of Patent: March 5, 2024Assignee: General Electric Technology GmbHInventors: Mita Babu Narayanan, Omar Jasim

Patent number: 9881430Abstract: A system includes plural, different sensors configured to be operably connected to a first vehicle. The sensors obtain status data indicative of a state of a cooling system of the first vehicle. The system includes a digital twin system having processors configured to modify the status data having sampling rates or resolutions that differ such that the status data that is modified has a common sampling rate resolution as that of other data. The processors create a digital twin matrix of the status data. The digital twin matrix is indicative of the state of the cooling system. The processors also determine a health score of the cooling system or simulate operation of the cooling system based on the digital twin matrix. The digital twin system is configured to change or control actual operation of the cooling system based on the health score or the operation that is simulated.Type: GrantFiled: February 22, 2017Date of Patent: January 30, 2018Assignee: General Electric CompanyInventors: Tapan Shah, Suresh Govindappa, Paul Nistler, Babu Narayanan
