Latest Patents

One of his latest patents is titled "Method, memory media and apparatus for detection of grid disconnect." This invention outlines a phase shift procedure for detecting a disconnect of a power grid from a feeder connected to a load and a distributed generator. The procedure compares the current phase shift of the output voltage of the distributed generator with a predetermined threshold. If the phase shift exceeds this threshold, a command is issued to disconnect the distributed generator from the feeder. To extend the range of detection, this phase shift procedure is employed when a power mismatch between the distributed generator and the load exceeds a threshold. Additionally, under or over frequency and voltage procedures are utilized when the power mismatch does not exceed the threshold.

Another significant patent is "Anti-islanding protection systems for synchronous machine based distributed generators." This system provides anti-islanding protection for synchronous machine-based distributed generators. It includes a frequency sensor that generates a generator frequency signal, a bandpass filter for filtering this signal, and a governor controller that uses the filtered frequency signal to generate a power feedback signal. The system also incorporates a voltage sensor that generates a generator terminal voltage signal and a feedback power calculator for generating a reactive feedback power signal.
