  • Patent number: 11954210
    Abstract: A hierarchical health index evaluation method for an intelligent substation includes: obtaining a basic health index of a device based on static information and dynamic information of the device; obtaining a device correlation based on a communication connection relationship between the device and another device, and correcting the basic health index of the device based on the device correlation to obtain a health index of the device; obtaining a layer-based health index of a layer based on a device health index and a device importance weight of the layer; obtaining a whole-station health index of an intelligent substation based on a layer-based health index of each layer and a sum of device importance weights of each layer; and regulating the intelligent substation based on a health index of each device in the intelligent substation, the layer-based health index of each layer, and the whole-station health index.

  • Publication number: 20240106140
    Abstract: A stacked I/O connector with surface mountable tails and a printed circuit board (PCB) configured to receive the connector. The connector may avoid terminal deformations or scratches when the connector is mounted to the PCB. The PCB may include solder pads on a single surface or both surfaces. The sold pads may be configured for the tails of the connector to be attached with a surface mount soldering technique. As a result, the connector has high density and high speed, requires, requires a smaller mounting area on a PCB, relaxes the limitations in routing PCB traces, and reduces the electrical performance deterioration caused by PCB trace routing limitations. The connector may have row-oriented terminal subassemblies, holes in the connector housing and other features to facilitate reliable manufacture and operation of the connector.
