abstract
Development of Intelligent Electronic Devices (IEDs) brings a leap in the development of substations. Large scale deployment of IEDs creates huge amount of data either recorder continuously or captured when IEDs are triggered by an event such as a fault or disturbance. The power system load increased to the point where the systems operate closer to the limits. The new developments enable much better monitoring to make sure the operation does not bring undesirable consequence. New automated monitoring and signal processing in substation has become a powerful feature necessary to assure the system is reliable and secure. In this paper, the new monitoring and signal processing solution in substation based on synchronized sampling technology and multifunctional IEDs (such as protection, controllers and PMUs) is proposed. To illustrate the above concepts new hardware and software solutions are envisioned. The hardware solution fully supports IEC 61850 protocol and takes cyber security into account. The software solution realizes the automated integration of substation IED data. 2010 IEEE.
