Publication number: 20220349924Abstract: The present invention disclosed a method for calculating an oscillation damping ratio of a power grid, and relates to the field of power system operation and control. When a power system oscillates, an oscillation period, two oscillation extreme points, and an oscillation direct current component start to be detected. Then an oscillation decay time constant is calculated according to the two oscillation extreme points and the oscillation direct current component. The oscillation damping ratio is calculated through the oscillation decay time constant and the oscillation period. Compared with a conventional fitting method, the conventional fitting method cannot calculate and analyze the oscillation damping ratio in a cast that a complete oscillation waveform is not obtained. The method proposed by the present inventive patent may complete the calculation of the oscillation damping ratio in a case of obtaining 2 pieces of data, so as to accelerate the speed of calculation.Type: ApplicationFiled: September 4, 2020Publication date: November 3, 2022Inventors: Yihui ZHANG, Libin WEN, Guangshi LIU, Qian DOU, Dongshan HUANG, Xiaoming WANG, Zhiyuan SUN, Guangling LU, Mingpo LI, Mosi LIU, Hao QIU, Xiaoyin QIU, Zhiyang YAO, Wei ZHANG

Publication number: 20210089170Abstract: A two dimensional touch sensor panel can be thermoformed or curved by another process to a three-dimensional touch sensor panel, and the three-dimensional touch sensor panel can be laminated to a three-dimension surface having a highly curved or spherical shape. In some examples, thermoforming a two-dimensional touch sensor panel into a three-dimensional touch sensor panel can result in strain of the touch electrodes, and can result in non-uniform three-dimensional touch electrodes (distortion of the two-dimensional touch electrode pattern). The strain can be a function of the curved touch-sensitive surface and/or process related mechanical strain from thermoforming. In some examples, a three-dimensional touch sensor panel can be formed with uniform area touch electrodes using a two-dimensional touch sensor panel pattern with non-uniform area touch electrodes in accordance with the strain pattern expected for a given curved surface and thermoforming technique.Type: ApplicationFiled: July 24, 2020Publication date: March 25, 2021Inventors: Supratik DATTA, Karan JAIN, Zhiyuan SUN, Ho Hyung LEE, Da YU, Wei LIN, Nathan K.
