Abstract: Apparatuses, systems, and methods for providing security in an intelligent electronic device (IED) are provided. In one aspect of the present disclosure, an IED is provided including at least one processor that receives a communication via a communication interface, the communication including an unencrypted file and a digital signature. The at least one processor decrypts the digital signature to obtain a first value, executes a hash function on the unencrypted file to obtain a second value, determines if the first value and second value match, and updates at least one firmware package stored in at least one memory of the IED with the unencrypted file if it is determined that the first value and the second value match.

Abstract: There is provided an intelligent electronic device for responding to user data and information requests regarding power usage and power quality for any metered point within a power distribution system. The intelligent electronic device includes a first network interface which receives client side information and data requests, which are processed in accordance with a network protocol and forwarded to a network interface via a network socket interface translator which translates management signals to facilitate the eventual data transfer. Protocol routines process the requests by constructing an internal data request in certain cases and forwards the internal data request to a data interface for translation from an internal data request format of the protocol routine format to a native database format. The database receives the translated request, and retrieves the requested data from a measuring unit of the electric power meter, and forwards the data back to the requesting client.

Abstract: A phasor measurement unit (PMU) of the present disclosure measures phasor, i.e., magnitude and phase angle of voltage and current, and related data from a specific location on the electrical gird synchronized to a common time source. The time-synchronized phasor is called a synchrophasor. In a system of the present disclosure, a plurality of PMUs transmit the synchrophasors and related data to a phasor data concentrator (PDC), which aggregates and time-aligns the data for real time and post analysis. The PMU of the present disclosure further functions as a power quality meter determining at least one of symmetrical components' phasor, frequency, rate of change of frequency, high-speed digital inputs, analog fundamental power and/or displacement power factor.
