Application using IEC 61850 in Digital Substations
Lower Installation Cost - quickly exchange data over the station LAN without wiring separate links for each relay
Lower Extension Costs - add devices and applications into an existing IEC 61850 system with minimal impact, if any, on existing equipment
Lower Integration Costs – to integrate substation data into the enterprise, use same networking technology widely used across the utility
TESLA 4000 provides support for IEC 61850-9-2LE process bus Sampled Values and IEC 61850-8-1 station bus applications. It implements mapping according to IEC 61850 edition 2 logical nodes and data models.
Use the TESLA 4000 to subscribe sampled values streams from merging units. Apply the Model 4000-SV to publish and subscribe to GOOSE messages from protective relays and switchgear. The Model 4000-SV also supports direct streaming of MMS reports to remote clients, eliminating the need for RTUs. The Model 4000-SV supports the top-down or bottom-up engineering process defined in the IEC 61850-6 standard. Such flexibility permits standardization and interoperability of fault and disturbance recording solutions as the industry moves towards fully digital substations.
Applications
Complete integrated insight of power system health
Performance monitoring of substation IEDs and equipment
Over 1000 user settable triggers capture vital information that could be missed by relays in the system
Information provided for wide area monitoring (WAMS) and analysis
As a PMU, streams up to 36 phasors, 24 analog quantities, and 64 digital statuses simultaneously
Specific Benefits of IEC 61850-Based Fault and Disturbance Recording System
Savings on costly wiring runs from instrument transformers (located in substation yards) to conventional DFRs located in substation control house
Practical elimination of CT saturation by eliminating copper cabling between CTs and DFRs
Absence of open CT secondary improves operational safety
Ease of commissioning, future modification, and expansion
Continuous self-monitoring capability using the IEC 61850 GOOSE repetition mechanism and IEC 61850 Edition 2 LGOS/LSVS logical nodes
Interoperability of DFR systems and protective relaying systems using common measurements available from merging units
