TESLA – Basic PMU Functionality
• Stream up to 12 phasors with existing PMU products
– New 4000 products and firmware-upgraded products can
stream up to 24 phasors
– Drag and drop PMU phasors
• Individual phase quantities, three-phase positive,
negative or zero sequence, or summated phasors
• Via Ethernet, serial port, or modem, up to 60 frames per
second (developing 120 fps)
• Complies with IEEE C37.118 (Level 0 and Level 1)
• Wide range frequency response (55 Hz – 65 Hz)
• Excellent time synchronization accuracy (+/- 0.75 µs)
• Extremely easy to configure and use
31
TESLA – Advanced PMU Functionality
• Synchronized sampling with IRIG signal (1 PPS)
– One sample insured to be within 0.75µs of UTC pulse
32
TESLA – Advanced PMU Functionality
• DSR – Dynamic PMU Recording in Swing Domain
– Triggered PMU magnitude and angle record
– Used for slow time-varying events
– Record at 1 sample/cycle
– 10 second to 15 minute record with automatic extension
– Extend up to 30 minutes under multiple trigger conditions
– Benefits
• Very valuable because PMU data record is triggered by and
associated with an event, and all related data is recorded
• Recorded data is identical to streamed data, so the DSR
effectively acts as a local PMU recorder – first level of
redundancy
33
TESLA – Advanced PMU Functionality
• LTR – Dynamic PMU Long Term Recording
– Long term PMU magnitude, angle, and frequency record
– User can define up to 60 trends
– Record sample rate – 10 to 3600 seconds
– Maintain log for 90 days
– Configure to overwrite or stop when full
– Configure trend-full output contact
– Benefits
• Capture long term variances
• LTR effectively acts as a local PMU recorder – second level
of redundancy
34
TESLA – Advanced PMU Functionality
• CDR – Continuous PMU Recording
– Record up to 36 channels at 6 to 60 frames per second
– Records stored locally on 4G flash memory
– Exceeds NERC CDR standards (PRC-002-1)
• Record anywhere from 3 to 140 days, depending upon config
– Automatic data overwrite
– User selectable range of data can be retrieved
– Effectively acts as a local PDC – third level of redundancy
– Provides for delayed recovery of post-event data
– Record and stream PMU data at different rates
35
TESLA – Advanced PMU Functionality
• Advanced Communications (4000 products)
– Stream PMU data simultaneously to two PDCs
– Supports data via two Ethernet ports (copper/optical)
– Each port has a unique MAC address
• Allows for unique routing and security
• Supports completely redundant communication paths
37
PMU Products – Activities and Plans
• CIP – Critical Infrastructure Protection
– Implement SSH and SSL for end-to-end accountability
– Implement password requirements per NERC requirements
– Utilize certificates for further authentication
– Developing comprehensive CIP solution via third party
security vendor – ASAT Solutions
38
PMU Products – Activities and Plans
• Active participant in PSRC C37.118.1/2

42
ERLPhase PMU Solutions
Benefits and Advantages
• Dedicated non-relay functionality
– Relays provide a limited local-element solution as opposed
to a system solution
– Primary role of relays is to protect an element
– Many electromechanical relays still in use
– Relay recording ability is often limited
– Relay-based recording station or system-wide analysis can
require piecing together multiple device records, and often
the use of additional processor or data storage hardware
– TESLA provides centralized, aligned, integrated PMU data
– System wide analysis capability
43
ERLPhase PMU Solutions
Benefits and Advantages
• Dedicated non-relay functionality
– Security issues
• Protection engineers often prefer that the protective relays
not be interrogated or modified for recording or data
gathering purposes
• Additional “openings” for remote record access increases
security risk and exposure
• Malicious modifications can cause serious consequences
