Introducing ERL I/O Expansion IED for standalone digital input/output expansion

ERLPhase introduces the ERL I/O Expansion IED, a stand-alone digital input/output expansion IED that supports 128 physical digital inputs (DIs), 15 output contacts, 128 subscription virtual channels for record triggering and 15 subscription virtual channels for output contact controls. The ERL I/O Expansion IED uses IEC 61850 GOOSE (Generic Object Oriented Substation Event) station bus (8-1) enabled protocol to publish and subscribe the binary input/output messages with ERL Devices and other IEDs supporting IEC 61850 GOOSE subscriptions.

Digital input statuses are communicated to multiple IED's in the network and to SCADA, which expands access to such information without costs to add additional IED's, and reduces the problems associated with having multiple IED's communicate with each other. In the event of a loss in the GPS time source, the I/O Expansion IED generates and provides 1pps unmodulated IRIG-B signal across up to 5 connected IED's, thereby ensuring time synchronization across these IED's.

TESLA 4000 power system recorder has provision for up to 256 virtual inputs to receive and record the time and status of events contained in IEC 61850 GOOSE messages. Connect two ERL I/O IED's with one TESLA 4000 to get 256 additional status inputs. Learn more at our website ERL I/O Expansion IED product page.

An Insight into IEC 61850 Protocol Implementation
Dr. Krish Narendra, PhD

On January 25, 2011, Dr. Krish Narendra presented at a luncheon meeting for the Winnipeg section of the IEEE Power & Energy Society.

Many publications and free online tutorials describe the IEC 61850 standard protocol, but very few implementation details have been published. This presentation included implementation details of the IEC 61850 protocol (both station bus 8-1, and process bus 9-2) with ERLPhase new generation relay and recording systems. It covered a brief introduction to the 61850 standards, logical node descriptions, GOOSE and Sampled Value publishing and subscriptions. An update on work being done to transmit Phasor Measurement Unit (PMU) data using the 61850 protocol was also discussed.

ERLPhase Power Technologies Announces S-PRO Sub-Harmonic Protection Relay

S-PRO Sub-Harmonic Protection Relay Winnipeg, Canada, Jan 25, 2011 – ERLPhase Power Technologies, a provider of easy-to-use protection relays and digital fault recorders, today announced the S-PRO Sub-Harmonic Protection Relay. Solutions, like the S-PRO, that help control harmonic oscillations are especially valuable in wind farm applications.

"The S-PRO was installed at a wind farm substation in Trimont, Minnesota to detect subharmonic oscillations occurring at adjacent wind farms connected to the series compensated line," said Pratap Mysore, Consulting Engineer at Xcel Energy. "In tests so far, the unit has performed well and the relay has been designed well to detect and protect against sustained harmonics from the wind turbines."

Since wind farms are generally located far away from load centers, power flow is increased using series capacitors to compensate for transmission line reactance. Unfortunately series capacitors can interact with the wind system, creating undamped sub-harmonic current oscillations that can cause serious damage to wind turbine controllers and also to conventional generators. The wind turbine's own mechanical system interactions (tower-to-blade) can also generate sub-harmonics, which are detrimental to induction generators, transformers, and may cause resonance at the point of common coupling in the electrical grid. By isolating the healthy grid from sub-harmonic generation sources, damage to the electrical interconnection can be prevented.

The S-PRO 4000 relay provides real-time processing of voltage and current signals with sub-harmonic monitoring at 1 Hz intervals between 5 and 25 Hz (5 Hz, 6 Hz, 7 Hz… 23 Hz, 24 Hz and 25 Hz). It protects the grid from sub-harmonic oscillations at the point-of-common-coupling every 1 second, with additional user-configurable delays. Like all ERLPhase relays, the S-PRO is easy-to-use with intuitive settings and analysis software. The S-PRO has already been installed with a lead customer and will begin full production shipment in Q1 2011.

"Our sub-harmonic protection relay (S-PRO) is the first advanced microprocessor-based relay with 10 second high speed recording capability. It can also be used for detecting Sub Synchronous Resonance (SSR) frequencies," commented Krish Narendra, Vice President of Technology and Quality at ERLPhase.

ERLPhase has a history of pioneering innovative protection and monitoring solutions including transformer loss-of-life monitoring in the T-PRO Transformer Protection Relay, dynamic swing recording in the L-PRO Transmission Line Protection Relay, the use of low impedance current inputs in the B-PRO Bus Protection Relay, and dynamic swing record capture with cross triggering in the TESLA Power System Recorder. All these innovations now find wide spread industry application.
