Complete Head-to-Toe Embedded Computing Solutions

Two minds are better than one. Adding locally intelligent nodes can create networks of surpassing efficiency and reliability. However, the exacting demands of power substation operations entail higher requirements for successful solutions. Power substations need powerful controllers with multiple serial ports for legacy device connectivity, and must also perform a multitude of front-end tasks, such as data acquisition, numerical computing, data distribution, and remote device monitoring and management. Moxa's Real Industrial Grade embedded computers provide head-to-toe embedded computing solutions for every level of the power substation.

System Requirements

• Embedded computers with high performance x86-based CPUs to act as protocol gateways, and to perform front-end computing and data acquisition tasks 
• A gateway that is capable of handling multiple devices with a variety of different protocols
• Onsite protection against strong EMI/EMS
• Multiple built-in Ethernet ports for network redundancy to ensure system non-stop operations
• Quick system response

Moxa Solution

Moxa's embedded computers provide a solution for all components of the bay-level substation. Moxa's DA-681 is an IEC 61850-3 certified x86-based rackmount embedded computer that acts as a protocol gateway. The DA-681 can reliably manage multiple devices running different protocols, such as IEDs, RTUs, and protection monitoring devices. Another x86-based embedded computer, the DA-682, is a front-end communication gateway that is able to perform protocol conversions, as well as front-end computing and data acquisition tasks.
 
At the substation layer, engineers and operators from the remote dispatch control center can retrieve data and monitor their systems with a telecontrol computer. Before implementing Moxa's solution, the substation control center had four different parallel systems—the protection management server, SCADA host, five-point prevention system, and a data logger server. By using Moxa's DA-710 x86-based embedded computer, all of the systems were integrated into one central management system. The DA-710 features a high performance CPU, and its 4 modular slots can handle multiple tasks. The DA-710 also functions as a substation back-end host to ensure availability for personnel at the remote dispatch control center.

Maximizing Energy Efficiency with Embedded Computers

The move from using traditional coal-fired power plants to renewable energy sources is well underway and is expected to accelerate considerably over the next decade. In particular, solar power has been recognized as a viable alternative, and in recent years a number of regions in both North America and Europe have enacted so-called FiT (Feed-in Tariff) legislation that allows individuals to sell solar generated power to their local power utility. Although industry experts expect this trend to continue, we should also see the introduction of a number of large-scale solar power plants that sell power to consumers through existing power grids. Moxa's embedded computers are expected to play a vital role at all levels of solar power plant operation.

System Requirements

• Real-time, web-based communication to monitor solar array performance, battery load, and energy generated and saved
• Front-end communication computer for remote monitoring, data acquisition, data logging, and protocol conversion
• Ability to handle multiple devices using different protocols for data communication
• Quick system response
• Onsite defense against strong EMI/EMS fields
• Meets IEC 61850-3 certification for power substation applications
• Multiple built-in Ethernet ports for establishing network redundancy to ensure system reliability and continuous operation

Moxa Solution

IA260—Moxa's RISC-based IA260 embedded computer is ideal for collecting and storing power usage data from subscribers. When installed in an apartment complex or even in individual units, the IA260 can be programmed to perform front-end computing and data acquisition tasks. The IA260 connects to power meters over an RS-485 connection, and data is transmitted to a central control center via Ethernet. Subscribers can access and check the billing system over the Internet.
 
W406 and UC-8410—The main task performed by Moxa's W406 RISC-based EDGE wireless embedded computer and UC-8410 RISC-based embedded computer is data acquisition. These embedded computers store power usage data, perform front-end data acquisition and processing, and then transmit the data to centralized servers.
 
DA-681—The DA-681 series x86-based embedded computer acts as a protocol gateway that handles multiple devices running different protocols for front-end computing and protocol conversion.
 
DA-682—The DA-682 x86-based embedded computer serves as an embedded backbone host and central controller for data analysis, data processing, and transmitting data back to the control center.

Solar Power Station Applications
 

All solar power stations include three major devices-a power inverter, a PLC, and meters. The power inverter converts the energy generated by the plant to power for end-users, and the PLC controls the base's sun tracking system. Although some inverters and meters are serial devices, these days PLCs are often Ethernet devices, and consequently the station needs to connect both serial and Ethernet devices to the Ethernet backbone network or the control center.
 
Power generation systems must be stable and reliable, which is why Ethernet redundancy in the Ethernet backbone is essential. In addition, solar farms are normally located in wide open locations such as deserts, which means that the devices should be able to endure wide variations in temperature.

Moxa Solution

With the NPort® S8000, you can connect all of your Ethernet and serial devices to the control center easily and economically with a single device. The NPort® S8000 is a compact and rugged all-in-one Ethernet switch and serial device server.
 
The NPort® S8000 provides Ethernet redundancy and ring structure to increase the reliability and availability of your system. Not only does the NPort® S8000 supports the standard STP/RSTP ring protocol but it also supports Moxa's proprietary Turbo Ring protocol, which has the world's fastest recovery time of under 20 millseconds.
 
With the NPort® S8000's dual power inputs and complete hardware protection, your network's stability is ensured. Aside from being certified to meet the UL508 international safety standards, the hardware is also fully equipped with surge protection for serial, Ethernet, and power to guard against voltage spikes.
