Distribution grid monitoring

A method, comprising:

• determining, by a field-programmable gate array (FPGA) configured to monitor a power grid and via a bootloader of the FPGA, whether a configuration of the FPGA requires updating, the configuration comprising one or more digital signal processor (DSP) applications (apps);
• updating, by the FPGA when required, the configuration of the FPGA;
• obtaining, by the FPGA, grid metrics of theft power grid measured using one or more sensors, the grid metrics comprising at least a voltage and a current of one or more measured phases of the power grid;
• determining, by the FPGA, a global positioning satellite (GPS)-based time using a GPS module;
• synchronizing, by the FPGA, zero crossing events of the grid metrics to the GPS-based time;
• processing, by the FPGA according to the one or more DSP apps, the grid metrics;
• and
• sharing, by the FPGA and via a communication interface, the processed grid metrics and synchronized zero crossing events.

A tangible, non-transitory, computer-readable medium storing program instructions that cause a computer to execute a process, the process, when executed by a processor of a device configured to monitor a power grid, operable to:

• determining, via a bootloader, whether a configuration of a field-programmable gate array (FPGA) of the device requires updating, the configuration comprising one or more digital signal processor (DSP) applications (apps);
• updating, when required, the configuration of the FPGA;
• obtaining grid metrics of a power grid using one or more sensors, the grid metrics comprising at least a voltage and a current of one or more measured phases of the power grid;
• determining a global positioning satellite (GPS)-based time using a GPS module;
• synchronizing zero crossing events of the grid metrics to the GPS-based time;
• processing, according to the one or more DSP apps, the grid metrics;
• and
• sharing, via a communication interface, the processed grid metrics and synchronized zero crossing events.
