3D BIM for Substations—Driving Efficiency from Design Through Operation and Maintenance

Original Broadcast September 30, 2014

In this webinar, PESTECH will describe their transition to intelligent substation design and its essential role in their corporate BIM strategy. The presentation will illustrate how a substation design process centered on an intelligent 3D model enables asset lifecycle information to become a standard project deliverable, and the means to realize the promise of BIM.

High Availability Networks. Application of IEC6439-3 Protocols for IEC61850 Process Bus implementation

Original Broadcast September 25, 2014

Networks can now be built for the first time with genuinely uninterrupted data communication between sensors, drives and measuring equipment. These new techniques, PRP (Parallel Redundancy Protocol) and HSR  (High-availability Seamless Redundancy), are based on the international IEC62439-3 standard and therefore guarantee future security and interoperability.  To fulfill some applications requirements we need to take an entirely new approach to the question of guaranteed high availability. The basis of this new approach to network redundancy is to have two independent active paths between two devices. The sender uses two independent network interfaces that transmit the same data simultaneously. The redundancy monitoring protocol then makes sure that the recipient uses only the first data packet and discards the second. If only one packet is received, the recipient knows that a failure has occurred on the other path.

This principle is employed by the parallel redundancy protocol (PRP), which is described in the IEC 62439-3 standard. PRP uses two independent networks with any topology and is not limited to ring networks. The two independent parallel networks may be MRP rings, RSTP networks and even networks without any redundancy at all. The principal advantage of PRP is its interruption-free switchovers, which take no time at all to switch over in failure situations and thus offer the highest possible availability. Naturally this applies only provided both networks do not fail simultaneously. High availability seamless redundancy (HSR) is a further development of the PRP approach, although HSR functions primarily as a protocol for creating media redundancy while PRP, as described, creates network redundancy. PRP and HSR are both described in the IEC 62439 3 standard. Unlike PRP, HSR is primarily designed for use in (redundantly coupled) ring topologies.

Understanding Moisture Dynamics in Power Transformers

Original Broadcast September 23, 2014

While the need to measure moisture in power transformers has been well documented and is universally accepted, the understanding of how moisture moves within a transformer under various conditions is less understood.  Please join us for this webcast sponsored by Vaisala.
