“…The purpose of deploying WAMS is to handle data collection, sharing coordinated control actions at a high granularity and over a wide area, which makes the grid more efficient and reliable [44]. While the concept of WAMS was proposed in 1980s and the first demonstration project was launched in 1995 in the US, WAMS finds its commercial deployment only over the last decade due to the trend of Smart Grid [45].…”

Abstract--This paper provides a solution to estimate synchrophasors with high accuracy at off-nominal frequencies using a nominal frequency clock. The sampling rate is fixed, while the amplitude of the sampled values is altered to generate a sequence of samples whose sampling frequency is synchronized to the power system frequency. The re-computation of the synchronized samples is done by cubic spline interpolation. The algorithm requires knowledge of the fundamental frequency of the power system which is estimated based on the phase angle difference between two phasors. The performance of the algorithm has been tested by simulation, through different scenarios, following the test conditions described in the IEEE Standard C37.118.1-2014a. The test cases include: steady-state with off-nominal frequencies, harmonic distortions, amplitude and phase modulations, positive and negative ramps of frequency, and frequency jump. The simulation results show the technique's capability in efficiently dealing with harmonics and off-nominal frequencies under static and dynamic conditions.

“…The automation process substation is oriented by the IEC 61850 standard [Tc5], which covers almost all aspects of Substation Automation System (SAS), providing new communication specifications to provide interoperability and flexibility in the operation of communication networks. However, this process of modernization has caused that the communication network management, in power substations, has become complex due to the large number of elements that comprise it (Intelligent Electronic Devices -IED: such as Breakers, switches, Protection and Control; Merging Units -MU, Network Switches, IEEE 1588 Master Clock), where each device executes functions with different requirements of connectivity, delay, bandwidth provisioning, synchronization and security [Hua+15].…”

Family ... an special group of people who love, respect and support each other.-Valentina Leal Dedicated to all my family, you know what I mean. Those people that, with or without blood-bond, are caring, supporting and loving you all the time, no matter what. A B S T R A C T Today, the communications network has become an essential element to the operation of any type of organization or infrastructure, such is the case of the electrical power substations. Such networks in particular, demand high levels of availability and reliability, as the substation is a key element in the chain of energy generation and distribution. However, although recent network modernization introduced new features that allow optimizing the operation of the substation, the variety of devices present in such environment (Intelligent Electronic Devices (IEDs), Merging Units (MUs), Network Switches, IEEE 1588 Master Clock) and the huge set of application-level protocols (Sampled Measured Values (SV), Generic Object Oriented Substation Event (GOOSE), Manufacturing Message Specification protocol (MMS), Precision Time Protocol (PTP), among others), increase the management complexity. Nevertheless, in recent years, data networks have been permeated by two major trends aiming to facilitate the administration of complex networks: Software Defined Networking (SDN) and virtualization technologies, which make the network management more flexible and enable the rapid development and deployment of network services. This thesis proposes a set of contributions to solve the research challenges around of the current operation of a power substation communication network that have not been tackled by the research community. To do that, it performs a comprehensive review of the appropriation of SDN as an enabler in the management and operation of the power substations communication networks. The first research challenge we identified in this work is that, to the best of our knowledge, there are not research works proposing a complete architecture for the management of the communications networks of the power substation; also existing works do not introduce the virtualization technologies as an enabler in this environment. They only present how the application of SDN concepts may improve the performance of different communication tasks in power substations. This thesis introduces a novel architecture called Smart Solution for Substation Networks (S3N), which presents a different way to represent the interaction among all elements involved in the operation of the power substation, taking the communications network as the central point and the SDN paradigm as a key element of its formulation. The second challenge found in this work is that there is no unique criterion to define the structure of th...
