METHODS AND APPARATUS FOR THE SENSING, COLLECTING, TRANSMISSION, STORAGE, AND DISSEMINATION OF HIGH-RESOLUTION POWER GRID ELECTRICAL MEASUREMENT DATA

Provided is a sensor network and method for monitoring electric power systems, collecting high-resolution data, and securely feeding it into an advanced time-series database. An apparatus for monitoring a power grid by collecting high-resolution electrical measurement data comprises an operative pair of signal analysers, the operative pair comprising: a micro-synchrophasor configured to operate in the frequency-domain to process an electrical signal and collect a first set of data points; and a power quality monitor configured to operate in the time-domain to process the electrical signal and collect a second set of data points; wherein the apparatus is configured to apply the same synchronised timestamp to the collected first and second sets of data points. A method for monitoring a power grid and collecting high-resolution electrical measurement data comprises the steps of collecting () a first set of data points using a micro-synchrophasor operating in the frequency-domain, collecting () a second set of data points using a power quality monitor operating in the time-domain, and applying () a synchronised timestamp to the collected first and second sets of data points.
