Intelligent Electronic Devices (IED) enable smart grid automation, SCADA integration, IEC 61850 interoperability, and substation protection, control, monitoring, and metering across T&D networks with digital relays, PLCs, reclosers, and smart meters.
The Important Points
IEDs are smart substation devices for protection, control, monitoring, metering, and SCADA using IEC 61850 communications.
- Functions: protection, control, monitoring, metering, communication
- Supports SCADA via IEC 61850 and legacy protocols
- Two-way communication enables active T&D automation
- Devices: digital relays, PLCs, reclosers, smart meters
- Deployed in substations, GIS, and harsh remote sites
New report reveals that the global intelligent electronic devices market to grow at a CAGR of 4.72 percent over the period 2015 and 2019.
The intelligent electronic devices IED plays a significant role in automating substations and efficient monitoring of power delivery systems. IED is used in the power system to define devices that have electrical protection and monitoring functionalities with an advanced intelligent control system and can perform two-way communication with SCADA devices and related systems.
Moreover, an IED has IEC 61580 protocol to communicate directly with the SCADA system that make it a unique device for active control in T&D and distribution automation of power delivery systems to the users. The major functions performed by IED are protection, monitoring, control, metering, and communication.
This report covers the present scenario and the growth prospects of the global intelligent electronic device market for the period 2015 and 2019. To calculate the market size, the report considers revenue generated through the sales of various intelligent electronic devices such as a digital relay, PLC, load tap controller, recloser, and smart meters across regions. The report includes a discussion of the key vendors operating in this market.
Smart grid investment worldwide is estimated to reach around $200 billion by 2015. The rapid development of smart grids has fostered the growth of several technologies, which includes smart meters, digital relays, load tap controllers and PLC. Smart Grids comprise various smart grid applications such as smart meters, supervisory control, data acquisition systems, and IT networks, which hold a sizeable market share in the Smart Grid market worldwide, which is witnessing rapid growth.
According to the report, increasing urbanization and industrialization are demanding intelligent GIS that require less space and are more suitable for harsh environments such as deserts and sea coasts where they can be remotely controlled and monitored. IEDs such as digital protective relays, load tap controllers, PLC and smart meters are most suitable for controlling and monitoring substations and industrial control systems in utilities.
