GOOSE Messaging over Substation Network

2017-08-25 19:11:07 | 日記
 

 

Background

 

Advances in remote communications have improved the quality and reliability of power distribution infastructure. Embracing these innovations, utilites have created intelligent substations based on high-capacity 4G LTE, rugged sensors and ethernet switches and intelligent grid hardware such as RTUs, advanced meters and reclosers. The intelligent substation allows utilities to: respond to changing loads, manage brownout and blackouts or even contain grid-wide collapse events with real-time remote monitoring and controls.

A large European utility decided to embrace these advances in smart-grid technology, but to build the smart-grid they faced real challenges: they needed to connect thousands of primary substations and hundreds of thousands of secondary substations to a smart-grid data center. This would require remote field communications devices that would fit the needs of their project with industrial wireless 3G or 4G networking.

In this project, the customer faced the following requirements:

Remote GOOSE Messaging routing between substations,

 Multiple Ethernet ports and two serial ports for multiple field devices,

 4G LTE backup to a Ethernet primary connection,

 DLMS/COSEM for AMI, 

 IEC 101 to IEC 104 conversion to support communication between serial field devices and the data center operating with Ethernet.


Solution 


Featuring five Ethernet ports and two serial ports, 4G LTE and a robust industrial desing, the InRouter915 exceeds the customer’s requirements. Multiple field RTU devices can connect to the InRouter 915's Ethernet ports to provide the network connection to the remote data center for remote data acquistion and controls. To provide intercommunication between smart-meters and the electronic counters (AMM) the IR915 creates a virtual serial network between the router's serial port by converting the serial data to Ethernet and routing the data over a secure encrypted tunnel.

The most demanding and significant of the requirements is GOOSE messaging communication between the secondary and primary substations. Utilizing low-latency 4G LTE and L2TPv3 tunneling, the InRouter915 provides a virtual local network to simulate a local Ethernet connection.

Teaching Robots to Teach Robots

2017-08-23 20:07:49 | 日記

 

There are two ways to teach a robot to do something: Demonstrate the task and make it replicate it, or program the task directly into its software. The first method usually means the robot is limited to performing a very specific task and isn’t able to transfer its skill to different situations, while the second method is usually time-consuming and requires skilled programmers to carry it out.

But what if it was possible to combine these two techniques? Researchers at the Massachusetts Institute of Technology (MIT) have developed a system that bridges both methods, enabling robots to transfer skills and knowledge amongst themselves. While it may sound like the beginning of a robot takeover, the new approach may prove useful in urgent situations, such as bomb disposal and disaster response.

The C-LEARN technique—described by the researchers in a paper recently accepted to the IEEE International conference on Robotics and Automation (ICRA)—involves providing a robot with a knowledge base of information of how to perform a task. A 3D interface is then used to show the robot a single demonstration of a specific task, allowing it to understand the motions it is being taught in the real world.

“This approach is actually very similar to how humans learn in terms of seeing how something’s done and connecting it to what we already know about the world,” said Claudia Pérez-D’Arpino, a PhD student who has written about the C-LEARN technique. “We can’t magically learn from a single demonstration, so we take new information and match it to previous knowledge about our environment.”

The teaching approach is similar to how humans learn. MIT CSAIL

“Having a knowledge base is fairly common, but what’s not common is integrating it with learning from demonstration,” said Dmitry Berenson, an assistant professor of computer science at the University of Michigan, who was not involved in the research.

“That’s very helpful, because if you are dealing with the same objects over and over again, you don’t want to then have to start from scratch to teach the robot every new task.”

A robot is therefore able to figure out how to perform a task even if there are obstacles in the way, as it does not simply learn one specific way to perform the action.

“It’s good for the field that we’re moving away from directly imitating motion, towards actually trying to infer the principles behind the motion,” Berenson said. “By using these learned constraints in a motion planner, we can make systems that are far more flexible than those which just try to mimic what’s being demonstrated.”
