“…Each zone has one or more protection devices associated with it, such as a wind turbine protection relay, step-up transformer protection relay, feeder protection relay, bus protection relay, and distance relay for the transmission line [22]. We considered three types of IEDs: a breaker IED, merging unit (MU) IED, and protection and control (P&C) IED [23][24][25][26]. Based on IEC 61850, the function of a MU IED is to acquire the voltage and current signals from the field CT and PT.…”

“…For MU-IEDs, we assumed that the sampling frequency of the voltage and current data was 6400 Hz for a 50 Hz power system, and each piece of sampling data was represented by 2 bytes [27]. Considering the 3-phase voltage and current measurement, the MU-IEDs send updated values of 76,800 bytes/s to the P&C server at the local control center [25]. Moreover, the CB-IED sends a status value of 16 bytes/s to the P&C server.…”

As we move toward increasing the grid integration of large-scale wind farms (WFs), reliable monitoring, protection, and control are needed to ensure grid stability. WFs are considered to be large and complex cyber physical systems owing to coupling between the electric power system and information and communication technologies (ICT). In this study, we proposed a framework for a cyber physical wind energy system (CPWES), which consists of four layers: a WF power system layer, data acquisition and monitoring layer, communication network layer, and application layer. We performed detailed network modeling for the WF system, including the wind turbines, meteorological mast (met-mast), and substation based on IEC 61400-25 and IEC 61850 standards. Network parameters and configuration were based on a real WF (Korean Southwest offshore project). The simulation results of the end-to-end delay were obtained for different WF applications, and they were compared with the timing requirements of the IEC 1646 standard. The proposed architecture represents a reference model for WF systems, and it can be used to enable the design of future CPWESs.

Wind energy is getting a considerable attention worldwide from the fraternity of the power system engineers as clean and green energy that can help reduce the carbon content and limit dependence on conventional fossil fuels. This has lead to the development of offshore wind farms in last few years. Real time monitoring and control of offshore wind farm require high speed, reliable, fault resilient, and cost effective communication infrastructure. The availability and reliability of wind energy mainly depend on resilient communication network. This can be achieved through a combination of redundancy and Quality of Service (QoS). In this paper, we have proposed fault resilient architecture of the medium scale offshore wind farm and simulated different fault scenarios based on IEC 61400-25 standard in OPNET. The wind farm communication is based on Transmission Control Protocol and Internet Protocol. The performance has been analysed with respect to QoS in terms of latency, traffic drop, and traffic congestion. V C 2013 AIP Publishing LLC [http://dx.

A highly reliable and deterministic communication network is required to guarantee the protection switch control and data acquisition of International Thermonuclear Experimental Reactor (ITER) pulsed power electrical network (PPEN) substation. This study aims at quantitatively assessing the availability indices and evaluating the end to end (ETE) time delay performance of PPEN communication network. The overall architecture of PPEN communication network is first introduced. Theoretical analysis of PPEN communication network under unrepairable and repairable condition are then examined and sensitivity analysis are carried out to find out the best way to improve the availability. Subsequently, OPNET modeler is used to simulate the message communication in PPEN communication network and time delay test was taken to prove the correctness of simulation model. The results indicate that PPEN communication network's availability indices meet ITER's requirement and the ETE time delay conforms to IEC 61850.
