SYSTEM AND METHOD FOR SYNCHRONIZING MULTIPLE GENERATORS WITH AN ELECTRICAL POWER DISTRIBUTION SYSTEM
Publication number: 20200293077Abstract: Systems and method for synchronizing power generators with a power grid are provided. One system among various implementations includes a plurality of synchronization modules, wherein each synchronization module corresponds to one power generator. The synchronization modules are configured to output a control signal to adjust a frequency of the respective power generator to correspond with the frequency of the existing power grid. The system also includes a central controller in communication with the plurality of synchronization modules. The central controller is configured to determine a propagation delay with respect to each synchronization module. The propagation delay is a measure of time for a signal to propagate from the respective synchronization module to the central controller. The central controller is further configured to send a control signal to each synchronization module to control when each synchronization module connects the respective power generator to the existing power grid.Type: ApplicationFiled: June 1, 2020Publication date: September 17, 2020Inventors: Frederick B.

Patent number: 8407016Abstract: There is provided herein methods and apparatus for apparatus for controlling the interconnection of an auxiliary AC generator with an electrical system, such as an electrical distribution system, e.g., a utility grid. A measuring circuit measures the frequency of an auxiliary AC generator and the phase angle between one voltage phase of the generator and the correspondent voltage phase of the electric utility's electricity supply lines, i.e., the grid, each of which are averaged and filtered. The measured frequency of the auxiliary AC generator is matched to the frequency of the electrical system and the measured phase angle of the generator is matched to the electric utility's electricity supply lines. Once matching is achieved to within a defined tolerance, interconnecting contactors are closed.Type: GrantFiled: January 25, 2011Date of Patent: March 26, 2013Assignee: Electro Industries/Gauge TechInventors: Frederick B.

Publication number: 20120146808Abstract: Systems and methods are provided for use in an IED that perform high resolution waveform capture to generate multi-rate waveform data in real-time. In one embodiment, high-resolution sampled data is dynamically pre-ordered into separate high resolution and low resolution data streams for presentation and storage. This pre-ordering of data is optimized so as to minimize the amount of data manipulation required to prepare the sampled data for eventual presentation and storage in the IED. Pre-ordering of data facilitates minimum performance impact so that continuous real-time data capture can be achieved.Type: ApplicationFiled: February 16, 2012Publication date: June 14, 2012Applicant: ELECTRO INDUSTRIES/GAUGE TECH.Inventors: Joseph Spanier, Hai Zhu, Frederick B.
