Intelligent electronic devices (IEDs) that are being deployed in substations today provide essential information, including operational and non-operational, required by many multiple users within the facility/utility. IED is any system that integrates one or more processors capable of receiving or transmitting data/control to or from an external entity (e.g., electronic multifunction meters, digital relays, controllers).
IEDs are the main components of substation integration and automation technologies. Automation includes the implementation of substation and feeder operating functions and software fluctuating from:
- Supervisory Control and Data Acquisition (SCADA)
- Alarm processing
- Automated volt/var control,
In order to maximize capital asset management and boost operating and maintenance (O&M) efficiency improvements with minimal human interference. You may also learn How To Fix [pii_email_37f47c404649338129d6] Error Code Easily.
Utilities are faced with the task of developing an uniform integration architecture which meets their unique requirements, can collect the wanted operational and non-operational data and deliver this information to those who have requirements to inspect the data. It’s important for any Extreme Networks Maintenance to provide real ongoing consultation that can ensure proactive integration of upgrades as older models fail. And how are the utilities meeting this task?
Common Substation Integration and Automation Technical Issues
- System Responsibilities
The system must connect with all IEDs in the substation, which involves polling of IEDs for readings and reminders of events. Data from all IEDs must be sent to the service provider in order to store the data or sent to a suitable place for the storage of substation data. The system handles data and control requests from users and data warehouses. The framework must isolate the proprietary features of the supplier by offering a standardized interface to the IEDs. In other words, regardless of the IED supplier, there should be a common interface.
- System Architecture
The various types of data and control which the system is supposed to enable depend on the selection of IEDs and devices in the system. This needs to be discussed on a substation-by-substation basis. The key requirement is to obtain analogue readings in such a way as to provide an accurate depiction of their concepts.
- Substation Host Processor
The sponsor substation must be based on industry standards and guidelines, improved networking capabilities, such as Ethernet, Telnet, UNIX, Windows 2000 or Linux, Debian, etc. It should also support an open architecture without patented frameworks or services.
An sector accepted relational database (RDB) backed with the important structured query language (SQL) capabilities and innovation computing must be facilitated. The RDB vendor must have redundancy facilities to sustain a reusable or backup database repository.
- Communication Interfaces
You will find interfaces to substation IEDs for acquiring data, decide the operating status of each IED, promote all communication protocols used among IEDs, and support the development of established standard protocols.
A line interface/process to the Energy Management System (EMS) would enable system operators to track and control each substation as well as the EMS to collect data from the substation integration and automation change at various different times. An interface to the distributor management system with about the same specifications as the EMS interface could exist.
- Protocol Fundamentals
The communication protocol enables communication processes between the two machines. Devices should have a similar protocol (and variant) in place. Any discrepancies in protocols can result in errors in communication.
The integration and automation architecture of substations must enable equipment from different suppliers to interact (interoperate) utilizing industry-standard protocols. The utility has the choice to select the right equipment for each application, given that the suppliers have built their devices to achieve maximum protocol compatibility.
Take Decisions Keeping The Future In Mind
Looking to the future, the time between both the present reality and the future projections seems to be diminishing. When a PC purchased today becomes redundant in six months by a new design with double the output at a lower cost, how could you preserve the advances in infrastructure, which that you are making today?
Obviously, there really is no way you could catch pace with all technological innovations in all fields on a continual basis. You have to be dependent on someone else to keep you updated, and from whom you are getting the information is important. With each order, you must analyze not only the current goods of the supplier but rather its future product creation strategies.
- Will the retailer constantly refine and update the products?
- Is the producer releasing new goods in order to fulfil potential needs?
- Do current goods have a conversion route to improved and future innovations?
Choosing the right supplier would ensure that you remain informed about recent and potential innovations and developments in the market and that you have access to new technology with the least effect on your current activity.
