Conventional electricity network is designed to be integrated with the latest technology, to be more economical, so you have to pay attention to the effect of carbon emissions, conservation and energy efficiency. The concern is application of the concept of smart grid digital technology and application of new components in the power sector to improve reliability, reduce costs, improve efficiency. In this paper discusses the necessary components to build a smart grid. Currently the smart grid concept has been applied to the electricity grid and energy management to shows the economic benefits that can be obtained.
Energy Management OverviewIn the project energy management, high performance, distributed, mission critical, control capability to monitor, control, and optimize the operation with low cost is goal for all companies. In this case we know that as Energy management System (EMS). As part of control system, SCADA has main role on this project. There are four items to be considered as below:
1. Real-time SCADA ApplicationsSCADA can be used in applications that require ease of monitoring as well as control, with a variety of interfaces and communication media available today (eg, computer, PDA, Touch Screen, TCP / IP, wireless, etc.). In the Real-time systems SCADA application is able to provide data control, including alarms / events, tagging, historian of data, data link, sequence control, and warehouse load applications that are used to monitor the performance of the control system.
2. Generation Dispatch and Control (GDC)GDC is usually used in factories and located within a more limited area because it can provide the functionality needed for sending and closed-loop digital control of several generators in the same time. GDC SCADA using high-speed communications media, such as local area network (LAN) to support the interchange schedule, dynamic schedule (load or generation in an out of the area), unintentional exchange of payback, time error correction, and security constraints of the transmission network.
3. Energy Scheduling and AccountingSCADA is the biggest part of a system control center in the process of energy scheduling, control production costs, scheduling interchange, exchange accounting deliberately, and adaptive weather forecasting demand. The data from the field which is has a function RTU that convey signals from the field to the control center. The data entry in the field is then translated by the SCADA Server that consists of several servers such as ADM, COM, and server2 applications such as Energy Management System.
4. Transmission Security ManagementTSM is the latest application that is able to analyze and optimize the use of the transmission network in a way that is reliable and safe. This strongly supports the SCADA functions as a reputable control system.
ConclusionElectric power SCADA systems application used to conduct electrical energy management. The function such as network application (state estimator, bus scheduling, online short circuit calculation, contingency evaluation), scheduling application (load forecast, hydrothermal coordination), power application (load frequency control, Interchange transaction scheduler) would be more reliable and can improve the efficiency in terms of cost and energy distribution. From my explanation above, the task of SCADA engineers are developing the SCADA system to be applied in real time systems. Duties include survey data, the database Input (topology substation) and drawing single line diagrams, Point-to-point, and to hand the stage over to the Customer.
