Publication number: 20250118963Abstract: The present disclosure provides a control method for suppressing an overvoltage of the receiving-end F/HMMC under the fault at the receiving-end alternating-current (AC) system of the hybrid high-voltage direct-current (HVDC) transmission system. After a short-circuit fault occurs in a receiving-end alternating-current (AC) system of the hybrid HVDC transmission system, an AC voltage drop is generated, and the effective voltage of the receiving-end AC bus at the current time is measured. Because the hybrid modular multilevel converter (MMC) has a capability of actively decreasing the DC voltage for operation, on a premise of ensuring that its output current is always within a rated current range, a control manner of setting the reference DC voltage and making the reference DC voltage not greater than the effective voltage of the AC bus enables receiving-end power to be sent out, thereby suppressing an overvoltage of the receiving-end F/HMMC.Type: ApplicationFiled: July 26, 2022Publication date: April 10, 2025Applicant: ZHEJIANG UNIVERSITYInventors: Zheng XU, Nan ZHANG, Zheren ZHANG

Patent number: 12260338Abstract: A transformer-based neural network includes at least one mask attention network (MAN). The MAN computes an original attention data structure that expresses influence between pairs of data items in a sequence of data items. The MAN then modifies the original data structure by mask values in a mask data structure, to produce a modified attention data structure. Compared to the original attention data structure, the modified attention data structure better accounts for the influence of neighboring data items in the sequence of data items, given a particular data item under consideration. The mask data structure used by the MAN can have static and/or machine-trained mask values. In one implementation, the transformer-based neural network includes at least one MAN in combination with at least one other attention network that does not use a mask data structure, and at least one feed-forward neural network.Type: GrantFiled: August 27, 2020Date of Patent: March 25, 2025Assignee: Microsoft Technology Licensing, LLCInventors: Jian Jiao, Yeyun Gong, Nan Duan, Ruofei Zhang, Ming Zhou
