Transmission & Distribution
Location: China
Project Introduction:
Generally, power substation systems include control, signal, measurement, protection, automation and remote handling equipment. Power substation systems are used to compile the data from these various devices and send the information to the central control station. Due to the different communication/ device/ protocol requests, the system must support various I/O inputs and integrate all information for the control center.
System Requirements:
Our customer was looking to improve their substation management and conversion control, allowing them to have more accurate information reading, as well as implement the following functions:
- Isolation and Surgeprotection to reduce heavy noise/electronic interference from the field
- A reliable system that can work in harsh environment
- Multiple Ethernet ports for data backup/communication
- Needs to meet IEC-61850 protocol requirements
- Compact and stable OS for application program development
- Real time synchronized watch to work with other power systems
- Stackable, due to cabin space limitations
Project Implementation:
| UNO-4678 |
Intel Celeron M UNO with 3 x LAN, 8 x COM, PC/104 |

System Description:
- Power stations operate 24/7, sometimes miles away from their target customers. Control centers need to monitor power status, make related adjustments, and respond to safety & efficiency needs. The main functions of the many devices used to handle these needs are:
- Measuring signals in field devices
- Transferring different data/protocols from devices and delivering them to the control center
- Analyzing device data and executing related controls
- Keeping allsystems in synchronization with eachother
- Remotelymonitoring all devices and data from the control center
- UNO-4678 is used to integrate these devices, deliver information/commands between devices and the control centers. When the power station is running there are many critical working issues from the field, which, if not responded to, can cause serious damage for the system and devices.
Conclusion:
After the implementation of the new system, the following benefits were realized:
- Build-inoptical isolated and surge protection
- Fanless, cable-less & diskless design
- Equipped with 3 x LANports, easy to switch data backup & communication with the control center
- Equipped with an industrial CompactFlash card
- Supports WinCE 5.0, easy to develop application programs for protocol transfer/conversion
- 1U Rack mount platform with robust and compact chassis design
