Smart substations are increasing in their popularity and as more system integrators are winning bids to update outdated substations, Advantech is helping to meet their needs with a range of Industrial PCs designed specifically for them. IEC-61850 is the specific standard for smart substations and defines the Ethernet protocol to be used for data communication and defines how devices in the substation communicate with each other. IEC-61850-3 devices need to meet electromagnetic interference (EMI), temperature, and shock/vibration resistance requirements.
The goal was to have a redundant intelligent substation IEC-61850 interface system with a SCADA LDMS (Local Display Maintenance System). This enables proper interaction with IED (Intelligent Electronics Devices) for protection and power system automation of utility power substations for NTPC LTD (National Thermal Power Corporation).
Legacy substation automation protocols and architectures provided the basic functionality for power system automation and were designed to accommodate the technical limitations for the available networking technology. Recently with the improvement in networking technology, what can be done has changed dramatically. Advanced communication techniques are used to address data management and simplify the integration of applications.
For this event, the main requirements were the ability to explore IEC 61850 SCL files, act as the MMS client and connect to hundreds of IEDs, simulate hundreds of IEC 61850 MMS servers, monitor & troubleshoot IEC 61850 data, create normal & abnormal system network conditions, measure the performance of IEC 61850 networks or IEDs, and record and and export test results in Excel.
The system integrator provided two of Advantech's UNO-2178 and WebAccess 8.0 SCADA software. The UNO-2178 is a small footprint fanless Embedded Box PC designed to work in temperatures as low as -40C and as high as 70C. The UNO-2178 is equipped with an Intel Atom N450/D510 CPU, Gigabit Ethernet ports, rich I/O, and 2 x mini PCIe slots. It also features WLAN, 3G expansion, and compatibility with Windows 7. They are Energy Star certified with IP40 anti-dust ingress protection. With an additional daughter board, the UNO-2178A supports one PC/104 plug-in card for further expansion making it the ideal solution for system integrators who need a turn-key solution and versatile application development path without breaking the bank or missing time to market deadlines.
Also used is Advantech's EKI-2748 Ethernet Switch which supports Gigabit with Ethernet and SFP/Combo ports. To enhance reliability in an industrial communication network, it's equipped with Advantech's own redundant network protocol, the X-Ring Pro, which provides users with an easy way to establish a redundant Ethernet network with an ultra-high speed recovery time of less than 20ms.
Furthermore, the EKI-2748 also supports advanced network standards to optimize network performance, reducing maintenance cost and secures network safety.
Going beyond SCADA, WebAccess 8.X is also a HTML5 Business Intelligent Dashboard which can be opened from anywhere on any HTML5 compatible browser. The Business Intelligent Dashboard analyses data and helps managers make decisions as to what to do and WebAccess 8.x also provides developers with the tools to design their own widgets and applications. Included is a set of Excel templates so users can build their own reports to help predict the status of equipment. Through HTML5, a limitless number of users, with varying access levels, are able to read information and make changes from wherever they are using either the Internet or Intranet.
