Synchronization measurement is very useful for power systems on phase measurement, fault location detection and others. This paper describes the concept of a frequency generator module to be used on synchronized acquisition systems. The frequency generator is modeled using a Numeric Controlled Oscillator (NCO) and a PI controller feeding back with phase error of one pulse per second (1-pps) output...
Power grid advances in the last years allowed new distributed applications developments. In this context, time synchronization is a very important issue, as many applications need to achieve high synchronization accuracy. The IEEE 1588–2008 standard [2] defines the second version of PTP, designed to achieve clock accuracy in the sub-microsecond range. In these scenarios Ethernet network redundancy...
With the growth in the number of PMUs in the electrical system, the discussion and understanding of performance requirements required in IEEE standard C37.118.1-2011 and its addendum IEEE C37.118.1a-2014 is of fundamental importance for the future specification, operation and maintenance of future interconnected power grids. This paper presents an analysis of two different algorithms for calculating...
