BACKGROUND: The power system, built on century-old technology and approaches, was designed to deliver electricity from large, remote power plants across significant distances to the cities and towns where electricity is used. For that reason, there is great need for an effective Protection and Control of the System to complete the chain of Generation, Transmission and Distribution to the users. FIG 1:1 ELEMENTS OF POWER SYSTEM INTERCONNECT MODULE METHODOLOGY: We shall use the devices; PCS-9881 and PCS-9882 Ethernet switch, RCS-9698G/H Communication Gateway, RCS-9700 automation system, RCS-9785 GPS Synchronization Clock and RCS-9794A/B Protocol Converter and the Automation Architecture module to achieve the maximum Protection and Control of he Substation and the 2x132kV HV Transmission lines from the Bay extension to the Substation. PCS-9881 and PCS-9882 Ethernet switch PCS-9881 and PCS-9882 Ethernet switch is intended for interconnection of 10/100/1000M adaptive Ethernet devices using twisted wire/Fiber optical connection in substation automation system. It adopts industrial level components and chips to ensure the reliable and high-speed data exchange, which makes it a compensation of insufficient application of commercial switch in a substation automation system. PCS-9881 and PCS-9882 are fully compatible with IEC 61850 and GOOSE communication in a digital substation automation system with distributed

The power system is installed within 5 electrical substations with emergency equipment, generators, medium voltage panels and transformers.This installation makes the power distribution to Petrobras Headquarters UOBS, which currently controls its offshore operation units (oil platform).The power system is divided into the following subsystems:
PCM600 IEC 61850 is based on the same concept for Relion protection and control IED, to
This report covers the real-time system design and the different components of the SCADA Energy Management System. Specifically, this report will focus on the General Electric XA/21 SCADA system and how it all fits together and how it provides a solution to end-users and administrators. The XA/21 is a very scalable and customizable system and that will be described at great length in this report (General Electric, 2013).
Sakari’s SK33, a digital switching system, uses components that are freely available in the open market and this is a major positive factor for Nora since other potential partners like NEC and Ericsson required purchase of components developed by parent companies. SK33 is attractive also since it is modular, its software could be upgraded to provide new services, it could interface easily with new equipment in the network, and it could lead to developing new switching systems. Sakari’s networks are easily adaptable, can cater to large exchanges in urban areas and small exchanges for rural needs.
This manual is intended to act as a handbook for commissioning works at substation site. The manual deals
In order to understanding the function of relays, software relay models must be realized and feasible alternative to studying the performance of protective relays. Relay models have been long used in a variety of tasks, such as designing new relaying algorithms, optimizing relay settings. Electric power utilities use compute-based relay models to confirm how the relay would perform during systems disturbances and normal operating conditions and to make the necessary corrective adjustment on the relay settings. [3][4]. One of the world-wide recognized, powerful analysis software package, is a MATLAB/SIMULINK, which has the capability for modeling, simulating and analyzing dynamic systems using SimPowerSystems toolbox, in side Simulink package, different parts of a system such as three phase transformer, three phase load, distributed parameters line, circuit breaker, etc can
Present power system is in need of a high level of redundancy and reliable protection devices along with the periodic maintenance to keep the system healthy. In these circumstances, there is a need for an efficient protection
Automation Business & Control & Relay panel Business were the other two business verticals of ERL; design of control and relay panel for the Electrical substation. Those verticals are our internal customers apart from the other Electricity boards. Energy meters are very critical in an electrical system as this is directly linked to the revenue generation of the utility. A minor flaw in the design may leads to huge loss to the Electrical utility. Hence the design validation of Energy meter is very critical in terms of the Business point of view. Also Bureau of Indian standard certification is a Mandatory requirement for selling this product in India. Hence our Management has given emphasis on the design validation to release a successful product in the
First and foremost, I would like to express gratitude to NLDC, Power System Operation Corporation Ltd (POSOCO) for providing me a magnificent opportunity in the form of this dissertation to learn.
Pertaining to the power grid with the connected bodies of the federal government and private sector the widespread accessibility via cyber space automated systems of power plants, distribution systems in its self could be problematic…i.e. could contribute to incapacitating large areas of power grids system via cyber-attacks. Possible consideration would be to isolate communications from standard cyber space via secured lines (buzzle.com 2016). Less debilitating to grid system are attacks as in one on one sabotage on individual power plants or remote distribution and substations that would interrupt local areas. Assuming power plants have adequate security on site will effectively reduce power plant attacks. In regards to distribution and substations in suburban or rural areas all one has to do would be to take a drive through the countryside or down a neighborhood to understand these are soft targets protect only by a chain-link fence.
This program allows you to communicate with plc. If the computer or SCADA application is out of order, the automation system will not be able to function properly. However, since there will be no communication during this period, data and alarm recording can not be performed on the computer.
Base layer is base for smart grid and self-healing control system and this base layer is collection of power grid and its equipment. The Support layer is collection of data and communication. Main function of this layer is to control the transmission of data and communication between different nodes. High speed, bi directional, real time transmission and communication is held by this layer. The application layer is collection of monitoring, decision-making, restoration.
HVDC transmission may also be selected for other technical benefits. HVDC can transfer power between separate AC networks. HVDC powerflow between separate AC systems can be automatically controlled to support either network during transient conditions, but without the risk that a major power system collapse in one network will lead to a collapse in the second. HVDC improves on system controllability, with at least one HVDC link embedded in an AC grid—in the deregulated environment, the controllability feature is particularly useful where control of energy trading is needed.
