Patent number: 9774216Abstract: To control a power state of a power system properly according to a communication state. A system for controlling a power system includes a plurality of sensor devices configured to output measurement data; a first control apparatus configured to estimate a first power state of the power system by using the measurement data obtained by the plurality of sensor devices, calculate a first controlled variable according to the estimated first power state, and output the calculated first controlled variable; and at least a second control apparatus configured to execute a predetermined control operation according to either the first controlled variable calculated in the first control apparatus, or a second controlled apparatus calculated in the second control apparatus. When it is not able to obtain part of the measurement data, the first control apparatus estimates the first power state by using predetermined measurement data among the obtained measurement data.Type: GrantFiled: July 10, 2012Date of Patent: September 26, 2017Assignee: Hitachi, Ltd.Inventors: Kenichiro Yamane, Kunihiko Tsunedomi, Noriyuki Uchiyama, Yasushi Tomita, Tsukasa Onishi, Masatoshi Kumagai

Patent number: 9722665Abstract: Methods of operating a communication node are provided. A method of operating a communication node may include transmitting a first power line communication signal from the communication node to a sensor device that is at or adjacent an electric grid device. The method may include receiving from the sensor device a second power line communication signal that is responsive to the first power line communication signal, at the communication node. Moreover, the method may include determining a distance between the communication node and the electric grid device by measuring an electrical parameter of the second power line communication signal, at the communication node. Related communication nodes are also described.Type: GrantFiled: May 6, 2014Date of Patent: August 1, 2017Assignee: DUKE ENERGY CORPORATIONInventors: Raiford Smith, Stuart Laval, Jason Handley

Patent number: 9714972Abstract: A power distribution unit including a base, at least one socket, at least one detecting unit and a management unit is provided. The socket is disposed at the base and has at least one power end and a ground end. The detecting unit is disposed at the base. When a plug is disposed at the socket, the detecting unit outputs an alarm signal if the plug is electrically connected to the power end of the socket but the plug is not electrically connected to the ground end of the socket. The management unit is electrically connected to the detecting unit and performs a predetermined operation in response to the alarm signal.Type: GrantFiled: November 2, 2015Date of Patent: July 25, 2017Assignee: International Business Machines CorporationInventors: Wei T. Chen, Yulianti Darmanto, Cheng-Hao Lin, Y. K. Liu, Claire H W Tsai

Patent number: 9685823Abstract: A system that includes a controller configured to receive data corresponding to at least a portion of a power system and one or more sensor measurements from one or more sensors in the power system. The controller may then generate a model of the power system based on at least a portion of the data and at least a portion of the sensor measurements such that the model may include one or more model measurements that correspond to the sensor measurements. After generating the model of the power system, the controller may determine one or more correction factors for the sensor measurements based on at least a portion of the sensor measurements and the model measurements, apply the correction factors to the sensor measurements to generate corrected sensor measurements, and determine one or more properties of the power system based on the corrected sensor measurements.Type: GrantFiled: March 30, 2012Date of Patent: June 20, 2017Assignee: General Electric CompanyInventors: Charles Brendan O'Sullivan, Michael Anthony McCormack

Patent number: 9673661Abstract: A transfer switch selectively couples at least two power sources to a load. The load may be a home, business, or vehicle. A current transformer is coupled to the output of the transfer switch and generates a load measurement signal that is proportional to the current or power output from the transfer switch. A controller receives the load measurement signal and a switch setting describing the operation of the switch. The controller generates data for a status message for display based on the load measurement signal and the switch setting. The status message may describe the power consumption of the load or indicate when an error has occurred.Type: GrantFiled: October 24, 2013Date of Patent: June 6, 2017Assignee: Kohler, Co.Inventor: Gregory Guse
